Summary

The NextGenPSD2 Framework Version 1.3.12 offers a modern, open, harmonised and interoperable set of Application Programming Interfaces (APIs) as the safest and most efficient way to provide data securely. The NextGenPSD2 Framework reduces XS2A complexity and costs, addresses the problem of multiple competing standards in Europe and, aligned with the goals of the Euro Retail Payments Board, enables European banking customers to benefit from innovative products and services ('Banking as a Service') by granting TPPs safe and secure (authenticated and authorised) access to their bank accounts and financial data.

The possible Approaches are:

  • Redirect SCA Approach
  • OAuth SCA Approach
  • Decoupled SCA Approach
  • Embedded SCA Approach without SCA method
  • Embedded SCA Approach with only one SCA method available
  • Embedded SCA Approach with Selection of a SCA method

Not every message defined in this API definition is necessary for all approaches. Furthermore this API definition does not differ between methods which are mandatory, conditional, or optional. Therefore for a particular implementation of a Berlin Group PSD2 compliant API it is only necessary to support a certain subset of the methods defined in this API definition.

Please have a look at the implementation guidelines if you are not sure which message has to be used for the approach you are going to use.

General Remarks on Data Types

The Berlin Group definition of UTF-8 strings in context of the PSD2 API has to support at least the following characters

a b c d e f g h i j k l m n o p q r s t u v w x y z

A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Payment Initiation Service (PIS)

The component for Payment Initiation Service (PIS) offers the following services:

  • Initiation and update of a payment request
  • Status information of a payment

Payment initiation request

This method is used to initiate a payment at the ASPSP.

Variants of payment initiation requests

This method to initiate a payment initiation at the ASPSP can be sent with either a JSON body.

There are the following payment products:

  • Payment products with payment information in JSON format:
    • sepa-credit-transfers
    • instant-sepa-credit-transfers
    • target-2-payments

Furthermore the request body depends on the payment-service:

  • payments: A single payment initiation request.

Single and multilevel SCA Processes

The payment initiation requests are independent from the need of one or multilevel SCA processing, i.e. independent from the number of authorisations needed for the execution of payments.

But the response messages are specific to either one SCA processing or multilevel SCA processing.

For payment initiation with multilevel SCA, this specification requires an explicit start of the authorisation, i.e. links directly associated with SCA processing like 'scaRedirect' or 'scaOAuth' cannot be contained in the response message of a Payment Initiation Request for a payment, where multiple authorisations are needed. Also if any data is needed for the next action, like selecting an SCA method is not supported in the response, since all starts of the multiple authorisations are fully equal. In these cases, first an authorisation sub-resource has to be generated following the 'startAuthorisation' link.

Value: "payments"

Payment service:

Possible values are:

  • payments
payment-product
required
string
Enum: "sepa-credit-transfers" "instant-sepa-credit-transfers" "target-2-payments"

The addressed payment product endpoint, e.g. for SEPA Credit Transfers (SCT). The ASPSP will publish which of the payment products/endpoints will be supported.

The following payment products are supported:

  • sepa-credit-transfers
  • instant-sepa-credit-transfers

header Parameters
X-Request-ID
required
string <uuid>
Example: 99391c7e-ad88-49ec-a2ad-99ddcb1f7721

ID of the request, unique to the call, as determined by the initiating party.

Digest
string
Example: SHA-256=hl1/Eps8BEQW58FJhDApwJXjGY4nr1ArGDHIT25vq6A=

Is contained if and only if the "Signature" element is contained in the header of the request.

Signature
string
Example: keyId="SN=9FA1,CA=CN=D-TRUST CA 2-1 2015,O=D-Trust GmbH,C=DE",algorithm="rsa-sha256", headers="Digest X-Request-ID PSU-ID TPP-Redirect-URI Date", signature="Base64(RSA-SHA256(signing string))"

A signature of the request by the TPP on application level. This might be mandated by ASPSP.

TPP-Signature-Certificate
string <byte>

The certificate used for signing the request, in base64 encoding. Must be contained if a signature is contained.

PSU-ID
string
Example: PSU-1234

Client ID of the PSU in the ASPSP client interface.

Might be mandated in the ASPSP's documentation.

It might be contained even if an OAuth2 based authentication was performed in a pre-step or an OAuth2 based SCA was performed in an preceding AIS service in the same session. In this case the ASPSP might check whether PSU-ID and token match, according to ASPSP documentation.

PSU-ID-Type
string

Type of the PSU-ID, needed in scenarios where PSUs have several PSU-IDs as access possibility.

In this case, the mean and use are then defined in the ASPSP’s documentation.

PSU-Corporate-ID
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

PSU-Corporate-ID-Type
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

Consent-ID
string (consentId)

This data element may be contained, if the payment initiation transaction is part of a session, i.e. combined AIS/PIS service. This then contains the consentId of the related AIS consent, which was performed prior to this payment initiation.

PSU-IP-Address
required
string <ipv4>
Example: 192.168.8.78

The forwarded IP Address header field consists of the corresponding http request IP Address field between PSU and TPP. If not available, the TPP shall use the IP Address used by the TPP when submitting this request.

TPP-Redirect-Preferred
boolean

If it equals "true", the TPP prefers a redirect over an embedded SCA approach. If it equals "false", the TPP prefers not to be redirected for SCA. The ASPSP will then choose between the Embedded or the Decoupled SCA approach, depending on the parameter TPP-Decoupled-Preferred and the choice of the SCA procedure by the TPP/PSU. If the parameter is not used, the ASPSP will choose the SCA approach to be applied depending on the SCA method chosen by the TPP/PSU.

TPP-Decoupled-Preferred
boolean

If it equals "true", the TPP prefers a decoupled SCA approach. If it equals "false", the TPP prefers not to use the decoupled approach for SCA. The ASPSP will then choose between the embedded or the redirect SCA approach, depending on the choice of the SCA procedure by the TPP/PSU. If the parameter is not used, the ASPSP will choose the SCA approach to be applied depending on the parameter TPP-Redirect-Preferred and the SCA method chosen by the TPP/PSU. The parameter might be ignored by the ASPSP. If both parameters TPP-Redirect-Preferred and TPP-Decoupled-Preferred are present and true, the request is still not rejected, but it is up to the ASPSP, which approach will actually be used.

Remark for Future: TPP-Redirect-Preferred and TPP-Decoupled-Preferred will be revised in future versions, maybe merged. Currently kept separate for downward compatibility.

TPP-Redirect-URI
string <uri>

URI of the TPP, where the transaction flow shall be redirected to after a Redirect.

Mandated for the Redirect SCA Approach, specifically when TPP-Redirect-Preferred equals "true". It is recommended to always use this header field.

Remark for Future: This field might be changed to mandatory in the next version of the specification.

TPP-Nok-Redirect-URI
string <uri>

If this URI is contained, the TPP is asking to redirect the transaction flow to this address instead of the TPP-Redirect-URI in case of a negative result of the redirect SCA method. This might be ignored by the ASPSP.

TPP-Rejection-NoFunds-Preferred
boolean

If it equals "true" then the TPP prefers a rejection of the payment initiation in case the ASPSP is providing an integrated confirmation of funds request an the result of this is that not sufficient funds are available.

If it equals "false" then the TPP prefers that the ASPSP is dealing with the payment initiation like in the ASPSPs online channel, potentially waiting for a certain time period for funds to arrive to initiate the payment.

This parameter might be ignored by the ASPSP.

TPP-Brand-Logging-Information
string

This header might be used by TPPs to inform the ASPSP about the brand used by the TPP towards the PSU. This information is meant for logging entries to enhance communication between ASPSP and PSU or ASPSP and TPP. This header might be ignored by the ASPSP.

TPP-Notification-URI
string

URI for the Endpoint of the TPP-API to which the status of the payment initiation should be sent. This header field may by ignored by the ASPSP.

For security reasons, it shall be ensured that the TPP-Notification-URI as introduced above is secured by the TPP eIDAS QWAC used for identification of the TPP. The following applies:

URIs which are provided by TPPs in TPP-Notification-URI shall comply with the domain secured by the eIDAS QWAC certificate of the TPP in the field CN or SubjectAltName of the certificate. Please note that in case of example-TPP.com as certificate entry TPP- Notification-URI like www.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications or notifications.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications would be compliant.

Wildcard definitions shall be taken into account for compliance checks by the ASPSP. ASPSPs may respond with ASPSP-Notification-Support set to false, if the provided URIs do not comply.

TPP-Notification-Content-Preferred
string

The string has the form

status=X1, ..., Xn

where Xi is one of the constants SCA, PROCESS, LAST and where constants are not repeated. The usage of the constants supports the of following semantics:

SCA: A notification on every change of the scaStatus attribute for all related authorisation processes is preferred by the TPP.

PROCESS: A notification on all changes of consentStatus or transactionStatus attributes is preferred by the TPP. LAST: Only a notification on the last consentStatus or transactionStatus as available in the XS2A interface is preferred by the TPP.

This header field may be ignored, if the ASPSP does not support resource notification services for the related TPP.

Example: 1234

The forwarded IP Port header field consists of the corresponding HTTP request IP Port field between PSU and TPP, if available.

PSU-Accept

Start the authorisation process for a payment initiation

Create an authorisation sub-resource and start the authorisation process. The message might in addition transmit authentication and authorisation related data.

This method is iterated n times for a n times SCA authorisation in a corporate context, each creating an own authorisation sub-endpoint for the corresponding PSU authorising the transaction.

The ASPSP might make the usage of this access method unnecessary in case of only one SCA process needed, since the related authorisation resource might be automatically created by the ASPSP after the submission of the payment data with the first POST payments/{payment-product} call.

The start authorisation process is a process which is needed for creating a new authorisation or cancellation sub-resource.

This applies in the following scenarios:

  • The ASPSP has indicated with a 'startAuthorisation' hyperlink in the preceding Payment initiation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms:

ID of the request, unique to the call, as determined by the initiating party.

PSU-ID
string
Example: PSU-1234

Client ID of the PSU in the ASPSP client interface.

Might be mandated in the ASPSP's documentation.

It might be contained even if an OAuth2 based authentication was performed in a pre-step or an OAuth2 based SCA was performed in an preceding AIS service in the same session. In this case the ASPSP might check whether PSU-ID and token match, according to ASPSP documentation.

PSU-ID-Type
string

Type of the PSU-ID, needed in scenarios where PSUs have several PSU-IDs as access possibility.

In this case, the mean and use are then defined in the ASPSP’s documentation.

PSU-Corporate-ID
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

PSU-Corporate-ID-Type
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

TPP-Redirect-Preferred
boolean

If it equals "true", the TPP prefers a redirect over an embedded SCA approach. If it equals "false", the TPP prefers not to be redirected for SCA. The ASPSP will then choose between the Embedded or the Decoupled SCA approach, depending on the parameter TPP-Decoupled-Preferred and the choice of the SCA procedure by the TPP/PSU. If the parameter is not used, the ASPSP will choose the SCA approach to be applied depending on the SCA method chosen by the TPP/PSU.

TPP-Redirect-URI
string <uri>

URI of the TPP, where the transaction flow shall be redirected to after a Redirect.

Mandated for the Redirect SCA Approach, specifically when TPP-Redirect-Preferred equals "true". It is recommended to always use this header field.

Remark for Future: This field might be changed to mandatory in the next version of the specification.

TPP-Nok-Redirect-URI
string <uri>

If this URI is contained, the TPP is asking to redirect the transaction flow to this address instead of the TPP-Redirect-URI in case of a negative result of the redirect SCA method. This might be ignored by the ASPSP.

TPP-Notification-URI
string

URI for the Endpoint of the TPP-API to which the status of the payment initiation should be sent. This header field may by ignored by the ASPSP.

For security reasons, it shall be ensured that the TPP-Notification-URI as introduced above is secured by the TPP eIDAS QWAC used for identification of the TPP. The following applies:

URIs which are provided by TPPs in TPP-Notification-URI shall comply with the domain secured by the eIDAS QWAC certificate of the TPP in the field CN or SubjectAltName of the certificate. Please note that in case of example-TPP.com as certificate entry TPP- Notification-URI like www.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications or notifications.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications would be compliant.

TPP-Notification-Content-Preferred
string

The string has the form

status=X1, ..., Xn

where Xi is one of the constants SCA, PROCESS, LAST and where constants are not repeated. The usage of the constants supports the of following semantics:

SCA: A notification on every change of the scaStatus attribute for all related authorisation processes is preferred by the TPP.

PROCESS: A notification on all changes of consentStatus or transactionStatus attributes is preferred by the TPP. LAST: Only a notification on the last consentStatus or transactionStatus as available in the XS2A interface is preferred by the TPP.

Update PSU data for payment initiation

This methods updates PSU data on the authorisation resource if needed. It may authorise a payment within the Embedded SCA Approach where needed.

Independently from the SCA Approach it supports e.g. the selection of the authentication method and a non-SCA PSU authentication.

There are several possible update PSU data requests in the context of payment initiation services needed, which depends on the SCA approach:

  • Redirect SCA Approach: A specific update PSU data request is applicable for
    • the selection of authentication methods, before choosing the actual SCA approach.
  • Decoupled SCA Approach: A specific update PSU data request is only applicable for
    • adding the PSU identification, if not provided yet in the payment initiation request or the account information consent request, or if no OAuth2 access token is used, or
    • the selection of authentication methods.
  • Embedded SCA Approach: The Update PSU Data request might be used
    • to add credentials as a first factor authentication data of the PSU and
    • to select the authentication method and
    • transaction authorisation.

The SCA Approach might depend on the chosen SCA method. For that reason, the following possible Update PSU data request can apply to all SCA approaches:

  • Select an SCA method in case of several SCA methods are available for the customer.

There are the following request types on this access path:

  • Update PSU identification
  • Update PSU authentication
  • Select PSU authorization method WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.
  • Transaction authorisation WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.

Start the authorisation process for the cancellation of the addressed payment

Creates an authorisation sub-resource and start the authorisation process of the cancellation of the addressed payment. The message might in addition transmit authentication and authorisation related data.

This method is iterated n times for a n times SCA authorisation in a corporate context, each creating an own authorisation sub-endpoint for the corresponding PSU authorising the cancellation-authorisation.

The ASPSP might make the usage of this access method unnecessary in case of only one SCA process needed, since the related authorisation resource might be automatically created by the ASPSP after the submission of the payment data with the first POST payments/{payment-product} call.

The start authorisation process is a process which is needed for creating a new authorisation or cancellation sub-resource.

This applies in the following scenarios:

  • The ASPSP has indicated with a 'startAuthorisation' hyperlink in the preceding payment initiation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms:
    • 'startAuthorisationWithPsuIdentification'
    • 'startAuthorisationWithPsuAuthentication'
    • 'startAuthorisationWithAuthentciationMethodSelection'
  • The related payment initiation cannot yet be executed since a multilevel SCA is mandated.
  • The ASPSP has indicated with a 'startAuthorisation' hyperlink in the preceding payment cancellation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms as indicated above.
  • The related payment cancellation request cannot be applied yet since a multilevel SCA is mandate for executing the cancellation.

Update PSU data for payment initiation cancellation

This method updates PSU data on the cancellation authorisation resource if needed. It may authorise a cancellation of the payment within the Embedded SCA Approach where needed.

Independently from the SCA Approach it supports e.g. the selection of the authentication method and a non-SCA PSU authentication.

This methods updates PSU data on the cancellation authorisation resource if needed.

There are several possible update PSU data requests in the context of a cancellation authorisation within the payment initiation services needed, which depends on the SCA approach:

  • Redirect SCA Approach: A specific Update PSU data request is applicable for
    • the selection of authentication methods, before choosing the actual SCA approach.
  • Decoupled SCA Approach: A specific Update PSU data request is only applicable for
    • adding the PSU Identification, if not provided yet in the payment initiation request or the Account Information Consent Request, or if no OAuth2 access token is used, or
    • the selection of authentication methods.
  • Embedded SCA Approach: The Update PSU data request might be used
    • to add credentials as a first factor authentication data of the PSU and
    • to select the authentication method and
    • transaction authorisation.

The SCA approach might depend on the chosen SCA method. For that reason, the following possible update PSU data request can apply to all SCA approaches:

  • Select an SCA method in case of several SCA methods are available for the customer.

There are the following request types on this access path:

  • Update PSU identification
  • Update PSU authentication
  • Select PSU authorization method WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.
  • Transaction Authorisation WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.

Account Information Service (AIS)

The Account Information Service (AIS) offers the following services:

  • Transaction reports for a given account or card account including balances if applicable
  • Balances of a given account or card account
  • A list of available accounts or card account
  • Account details of a given account or card account or of the list of all accessible accounts or card account relative to a granted consent

Read account list

Read the identifiers of the available payment account together with booking balance information, depending on the consent granted.

It is assumed that a consent of the PSU to this access is already given and stored on the ASPSP system. The addressed list of accounts depends then on the PSU ID and the stored consent addressed by consentId, respectively the OAuth2 access token.

Returns all identifiers of the accounts, to which an account access has been granted to through the /consents endpoint by the PSU. In addition, relevant information about the accounts and hyperlinks to corresponding account information resources are provided if a related consent has been already granted.

Remark: Note that the /consents endpoint optionally offers to grant an access on all available payment accounts of a PSU. In this case, this endpoint will deliver the information about all available payment accounts of the PSU at this ASPSP.

Read transaction list of an account

Read transaction reports or transaction lists of a given account addressed by "account-id", depending on the steering parameter "bookingStatus" together with balances.

For a given account, additional parameters are e.g. the attributes "dateFrom" and "dateTo". The ASPSP might add balance information, if transaction lists without balances are not supported.

Authorizations:
NoneBearerAuthOAuth
path Parameters
account-id
required
string (accountId)
Example: qwer3456tzui7890

This identification is denoting the addressed (card) account. The account-id is retrieved by using a "Read Account List" or "Read Card Account list" call. The account-id is the "resourceId" attribute of the account structure. Its value is constant at least throughout the lifecycle of a given consent.

query Parameters
dateFrom
string <date>

Conditional: Starting date (inclusive the date dateFrom) of the transaction list, mandated if no delta access is required and if bookingStatus does not equal "information".

For booked transactions, the relevant date is the booking date.

For pending transactions, the relevant date is the entry date, which may not be transparent neither in this API nor other channels of the ASPSP.

dateTo
string <date>

End date (inclusive the data dateTo) of the transaction list, default is "now" if not given.

Might be ignored if a delta function is used.

For booked transactions, the relevant date is the booking date.

For pending transactions, the relevant date is the entry date, which may not be transparent neither in this API nor other channels of the ASPSP.

entryReferenceFrom
string

This data attribute is indicating that the AISP is in favour to get all transactions after the transaction with identification entryReferenceFrom alternatively to the above defined period. This is a implementation of a delta access. If this data element is contained, the entries "dateFrom" and "dateTo" might be ignored by the ASPSP if a delta report is supported.

Optional if supported by API provider.

bookingStatus
required
string
Enum: "information" "booked" "pending" "both" "all"

Permitted codes are

  • "booked",

Create consent

This method create a consent resource, defining access rights to dedicated accounts of a given PSU-ID. These accounts are addressed explicitly in the method as parameters as a core function.

Side Effects When this consent request is a request where the "recurringIndicator" equals "true", and if it exists already a former consent for recurring access on account information for the addressed PSU, then the former consent automatically expires as soon as the new consent request is authorised by the PSU.

Optional Extension: As an option, an ASPSP might optionally accept a specific access right on the access on all PSD2 related services for all available accounts.

As another option an ASPSP might optionally also accept a command, where only access rights are inserted without mentioning the addressed account. The relation to accounts is then handled afterwards between PSU and ASPSP. This option is not supported for the Embedded SCA Approach. As a last option, an ASPSP might in addition accept a command with access rights

  • to see the list of available payment accounts or
  • to see the list of available payment accounts with balances.

X-Request-ID
required
string <uuid>
Example: 99391c7e-ad88-49ec-a2ad-99ddcb1f7721

ID of the request, unique to the call, as determined by the initiating party.

Digest
string
Example: SHA-256=hl1/Eps8BEQW58FJhDApwJXjGY4nr1ArGDHIT25vq6A=

Is contained if and only if the "Signature" element is contained in the header of the request.

Signature
string
Example: keyId="SN=9FA1,CA=CN=D-TRUST CA 2-1 2015,O=D-Trust GmbH,C=DE",algorithm="rsa-sha256", headers="Digest X-Request-ID PSU-ID TPP-Redirect-URI Date", signature="Base64(RSA-SHA256(signing string))"

A signature of the request by the TPP on application level. This might be mandated by ASPSP.

TPP-Signature-Certificate
string <byte>

The certificate used for signing the request, in base64 encoding. Must be contained if a signature is contained.

PSU-ID
string
Example: PSU-1234

Client ID of the PSU in the ASPSP client interface.

Might be mandated in the ASPSP's documentation.

It might be contained even if an OAuth2 based authentication was performed in a pre-step or an OAuth2 based SCA was performed in an preceding AIS service in the same session. In this case the ASPSP might check whether PSU-ID and token match, according to ASPSP documentation.

PSU-ID-Type
string

Type of the PSU-ID, needed in scenarios where PSUs have several PSU-IDs as access possibility.

In this case, the mean and use are then defined in the ASPSP’s documentation.

PSU-Corporate-ID
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

PSU-Corporate-ID-Type
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

TPP-Redirect-Preferred
boolean

If it equals "true", the TPP prefers a redirect over an embedded SCA approach. If it equals "false", the TPP prefers not to be redirected for SCA. The ASPSP will then choose between the Embedded or the Decoupled SCA approach, depending on the parameter TPP-Decoupled-Preferred and the choice of the SCA procedure by the TPP/PSU. If the parameter is not used, the ASPSP will choose the SCA approach to be applied depending on the SCA method chosen by the TPP/PSU.

TPP-Decoupled-Preferred
boolean

If it equals "true", the TPP prefers a decoupled SCA approach. If it equals "false", the TPP prefers not to use the decoupled approach for SCA. The ASPSP will then choose between the embedded or the redirect SCA approach, depending on the choice of the SCA procedure by the TPP/PSU. If the parameter is not used, the ASPSP will choose the SCA approach to be applied depending on the parameter TPP-Redirect-Preferred and the SCA method chosen by the TPP/PSU. The parameter might be ignored by the ASPSP. If both parameters TPP-Redirect-Preferred and TPP-Decoupled-Preferred are present and true, the request is still not rejected, but it is up to the ASPSP, which approach will actually be used.

Remark for Future: TPP-Redirect-Preferred and TPP-Decoupled-Preferred will be revised in future versions, maybe merged. Currently kept separate for downward compatibility.

TPP-Redirect-URI
string <uri>

URI of the TPP, where the transaction flow shall be redirected to after a Redirect.

Mandated for the Redirect SCA Approach, specifically when TPP-Redirect-Preferred equals "true". It is recommended to always use this header field.

Remark for Future: This field might be changed to mandatory in the next version of the specification.

TPP-Nok-Redirect-URI
string <uri>

If this URI is contained, the TPP is asking to redirect the transaction flow to this address instead of the TPP-Redirect-URI in case of a negative result of the redirect SCA method. This might be ignored by the ASPSP.

TPP-Brand-Logging-Information
string

This header might be used by TPPs to inform the ASPSP about the brand used by the TPP towards the PSU. This information is meant for logging entries to enhance communication between ASPSP and PSU or ASPSP and TPP. This header might be ignored by the ASPSP.

TPP-Notification-URI
string

URI for the Endpoint of the TPP-API to which the status of the payment initiation should be sent. This header field may by ignored by the ASPSP.

For security reasons, it shall be ensured that the TPP-Notification-URI as introduced above is secured by the TPP eIDAS QWAC used for identification of the TPP. The following applies:

URIs which are provided by TPPs in TPP-Notification-URI shall comply with the domain secured by the eIDAS QWAC certificate of the TPP in the field CN or SubjectAltName of the certificate. Please note that in case of example-TPP.com as certificate entry TPP- Notification-URI like www.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications or notifications.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications would be compliant.

Wildcard definitions shall be taken into account for compliance checks by the ASPSP. ASPSPs may respond with ASPSP-Notification-Support set to false, if the provided URIs do not comply.

TPP-Notification-Content-Preferred
string

The string has the form

status=X1, ..., Xn

where Xi is one of the constants SCA, PROCESS, LAST and where constants are not repeated. The usage of the constants supports the of following semantics:

SCA: A notification on every change of the scaStatus attribute for all related authorisation processes is preferred by the TPP.

PROCESS: A notification on all changes of consentStatus or transactionStatus attributes is preferred by the TPP. LAST: Only a notification on the last consentStatus or transactionStatus as available in the XS2A interface is preferred by the TPP.

This header field may be ignored, if the ASPSP does not support resource notification services for the related TPP.

Start the authorisation process for a consent

Create an authorisation sub-resource and start the authorisation process of a consent. The message might in addition transmit authentication and authorisation related data.

his method is iterated n times for a n times SCA authorisation in a corporate context, each creating an own authorisation sub-endpoint for the corresponding PSU authorising the consent.

The ASPSP might make the usage of this access method unnecessary, since the related authorisation resource will be automatically created by the ASPSP after the submission of the consent data with the first POST consents call.

The start authorisation process is a process which is needed for creating a new authorisation or cancellation sub-resource.

This applies in the following scenarios:

  • The ASPSP has indicated with an 'startAuthorisation' hyperlink in the preceding Payment initiation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms:
    • 'startAuthorisationWithPsuIdentification',
    • 'startAuthorisationWithPsuAuthentication'
    • 'startAuthorisationWithEncryptedPsuAuthentication'
    • 'startAuthorisationWithAuthentciationMethodSelection'
  • The related payment initiation cannot yet be executed since a multilevel SCA is mandated.
  • The ASPSP has indicated with an 'startAuthorisation' hyperlink in the preceding payment cancellation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms as indicated above.
  • The related payment cancellation request cannot be applied yet since a multilevel SCA is mandate for executing the cancellation.

Update PSU Data for consents

This method update PSU data on the consents resource if needed. It may authorise a consent within the Embedded SCA Approach where needed.

Independently from the SCA Approach it supports e.g. the selection of the authentication method and a non-SCA PSU authentication.

This methods updates PSU data on the cancellation authorisation resource if needed.

There are several possible update PSU data requests in the context of a consent request if needed, which depends on the SCA approach:

  • Redirect SCA Approach: A specific Update PSU data request is applicable for
    • the selection of authentication methods, before choosing the actual SCA approach.
  • Decoupled SCA Approach: A specific update PSU data request is only applicable for
    • adding the PSU Identification, if not provided yet in the payment initiation request or the Account Information Consent Request, or if no OAuth2 access token is used, or
    • the selection of authentication methods.
  • Embedded SCA Approach: The Update PSU data request might be used
    • to add credentials as a first factor authentication data of the PSU and
    • to select the authentication method and
    • transaction authorisation.

The SCA Approach might depend on the chosen SCA method. For that reason, the following possible update PSU data request can apply to all SCA approaches:

  • Select an SCA method in case of several SCA methods are available for the customer.

There are the following request types on this access path:

  • Update PSU identification
  • Update PSU authentication
  • Select PSU authorization method WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.
  • Transaction Authorisation WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.

Common Services

Processes on starting authorisations, update PSU identification or PSU authentication data and explicit authorisation of transactions by using SCA are very similar in PIS and AIS services. The API calls supporting these processes are described in the following independently from the service/endpoint. For reasons of clarity, the endpoints are defined always for the Payment Initiation Service, the payment cancellation, the Account Information Service (Consents) separately. These processes usually are used following a hyperlink of the ASPSP.

Start the authorisation process for a payment initiation

Create an authorisation sub-resource and start the authorisation process. The message might in addition transmit authentication and authorisation related data.

This method is iterated n times for a n times SCA authorisation in a corporate context, each creating an own authorisation sub-endpoint for the corresponding PSU authorising the transaction.

The ASPSP might make the usage of this access method unnecessary in case of only one SCA process needed, since the related authorisation resource might be automatically created by the ASPSP after the submission of the payment data with the first POST payments/{payment-product} call.

The start authorisation process is a process which is needed for creating a new authorisation or cancellation sub-resource.

This applies in the following scenarios:

  • The ASPSP has indicated with a 'startAuthorisation' hyperlink in the preceding Payment initiation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms:
    • 'startAuthorisationWithPsuIdentification'
    • 'startAuthorisationWithPsuAuthentication'
    • 'startAuthorisationWithEncryptedPsuAuthentication'
    • 'startAuthorisationWithAuthentciationMethodSelection'
  • The related payment initiation cannot yet be executed since a multilevel SCA is mandated.
  • The ASPSP has indicated with a 'startAuthorisation' hyperlink in the preceding Payment cancellation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms as indicated above.
  • The related payment cancellation request cannot be applied yet since a multilevel SCA is mandate for executing the cancellation.

ID of the request, unique to the call, as determined by the initiating party.

PSU-ID
string
Example: PSU-1234

Client ID of the PSU in the ASPSP client interface.

Might be mandated in the ASPSP's documentation.

It might be contained even if an OAuth2 based authentication was performed in a pre-step or an OAuth2 based SCA was performed in an preceding AIS service in the same session. In this case the ASPSP might check whether PSU-ID and token match, according to ASPSP documentation.

PSU-ID-Type
string

Type of the PSU-ID, needed in scenarios where PSUs have several PSU-IDs as access possibility.

In this case, the mean and use are then defined in the ASPSP’s documentation.

PSU-Corporate-ID
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

PSU-Corporate-ID-Type
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

TPP-Redirect-Preferred
boolean

If it equals "true", the TPP prefers a redirect over an embedded SCA approach. If it equals "false", the TPP prefers not to be redirected for SCA. The ASPSP will then choose between the Embedded or the Decoupled SCA approach, depending on the parameter TPP-Decoupled-Preferred and the choice of the SCA procedure by the TPP/PSU. If the parameter is not used, the ASPSP will choose the SCA approach to be applied depending on the SCA method chosen by the TPP/PSU.

TPP-Redirect-URI
string <uri>

URI of the TPP, where the transaction flow shall be redirected to after a Redirect.

Mandated for the Redirect SCA Approach, specifically when TPP-Redirect-Preferred equals "true". It is recommended to always use this header field.

Remark for Future: This field might be changed to mandatory in the next version of the specification.

TPP-Nok-Redirect-URI
string <uri>

If this URI is contained, the TPP is asking to redirect the transaction flow to this address instead of the TPP-Redirect-URI in case of a negative result of the redirect SCA method. This might be ignored by the ASPSP.

TPP-Notification-URI
string

URI for the Endpoint of the TPP-API to which the status of the payment initiation should be sent. This header field may by ignored by the ASPSP.

For security reasons, it shall be ensured that the TPP-Notification-URI as introduced above is secured by the TPP eIDAS QWAC used for identification of the TPP. The following applies:

URIs which are provided by TPPs in TPP-Notification-URI shall comply with the domain secured by the eIDAS QWAC certificate of the TPP in the field CN or SubjectAltName of the certificate. Please note that in case of example-TPP.com as certificate entry TPP- Notification-URI like www.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications or notifications.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications would be compliant.

Wildcard definitions shall be taken into account for compliance checks by the ASPSP. ASPSPs may respond with ASPSP-Notification-Support set to false, if the provided URIs do not comply.

TPP-Notification-Content-Preferred
string

The string has the form

status=X1, ..., Xn

where Xi is one of the constants SCA, PROCESS, LAST and where constants are not repeated. The usage of the constants supports the of following semantics:

SCA: A notification on every change of the scaStatus attribute for all related authorisation processes is preferred by the TPP.

PROCESS: A notification on all changes of consentStatus or transactionStatus attributes is preferred by the TPP. LAST: Only a notification on the last consentStatus or transactionStatus as available in the XS2A interface is preferred by the TPP.

This header field may be ignored, if the ASPSP does not support resource notification services for the related TPP.

Independently from the SCA Approach it supports e.g. the selection of the authentication method and a non-SCA PSU authentication.

There are several possible update PSU data requests in the context of payment initiation services needed, which depends on the SCA approach:

  • Redirect SCA Approach: A specific update PSU data request is applicable for
    • the selection of authentication methods, before choosing the actual SCA approach.
  • Decoupled SCA Approach: A specific update PSU data request is only applicable for
    • adding the PSU identification, if not provided yet in the payment initiation request or the account information consent request, or if no OAuth2 access token is used, or
    • the selection of authentication methods.
  • Embedded SCA Approach: The Update PSU Data request might be used
    • to add credentials as a first factor authentication data of the PSU and
    • to select the authentication method and
    • transaction authorisation.

The SCA Approach might depend on the chosen SCA method. For that reason, the following possible Update PSU data request can apply to all SCA approaches:

  • Select an SCA method in case of several SCA methods are available for the customer.

There are the following request types on this access path:

  • Update PSU identification
  • Update PSU authentication
  • Select PSU authorization method WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.
  • Transaction authorisation WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.

Start the authorisation process for the cancellation of the addressed payment

Creates an authorisation sub-resource and start the authorisation process of the cancellation of the addressed payment. The message might in addition transmit authentication and authorisation related data.

This method is iterated n times for a n times SCA authorisation in a corporate context, each creating an own authorisation sub-endpoint for the corresponding PSU authorising the cancellation-authorisation.

The ASPSP might make the usage of this access method unnecessary in case of only one SCA process needed, since the related authorisation resource might be automatically created by the ASPSP after the submission of the payment data with the first POST payments/{payment-product} call.

The start authorisation process is a process which is needed for creating a new authorisation or cancellation sub-resource.

This applies in the following scenarios:

  • The ASPSP has indicated with a 'startAuthorisation' hyperlink in the preceding payment initiation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms:
    • 'startAuthorisationWithPsuIdentification'
    • 'startAuthorisationWithPsuAuthentication'
    • 'startAuthorisationWithAuthentciationMethodSelection'
  • The related payment initiation cannot yet be executed since a multilevel SCA is mandated.
  • The ASPSP has indicated with a 'startAuthorisation' hyperlink in the preceding payment cancellation response that an explicit start of the authorisation process is needed by the TPP. The 'startAuthorisation' hyperlink can transport more information about data which needs to be uploaded by using the extended forms as indicated above.
  • The related payment cancellation request cannot be applied yet since a multilevel SCA is mandate for executing the cancellation.

TPP-Redirect-Preferred
boolean

If it equals "true", the TPP prefers a redirect over an embedded SCA approach. If it equals "false", the TPP prefers not to be redirected for SCA. The ASPSP will then choose between the Embedded or the Decoupled SCA approach, depending on the parameter TPP-Decoupled-Preferred and the choice of the SCA procedure by the TPP/PSU. If the parameter is not used, the ASPSP will choose the SCA approach to be applied depending on the SCA method chosen by the TPP/PSU.

TPP-Redirect-URI
string <uri>

URI of the TPP, where the transaction flow shall be redirected to after a Redirect.

Mandated for the Redirect SCA Approach, specifically when TPP-Redirect-Preferred equals "true". It is recommended to always use this header field.

Remark for Future: This field might be changed to mandatory in the next version of the specification.

TPP-Nok-Redirect-URI

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

PSU-Corporate-ID-Type
string

Might be mandated in the ASPSP's documentation. Only used in a corporate context.

TPP-Redirect-Preferred
boolean

If it equals "true", the TPP prefers a redirect over an embedded SCA approach. If it equals "false", the TPP prefers not to be redirected for SCA. The ASPSP will then choose between the Embedded or the Decoupled SCA approach, depending on the parameter TPP-Decoupled-Preferred and the choice of the SCA procedure by the TPP/PSU. If the parameter is not used, the ASPSP will choose the SCA approach to be applied depending on the SCA method chosen by the TPP/PSU.

TPP-Redirect-URI
string <uri>

URI of the TPP, where the transaction flow shall be redirected to after a Redirect.

Mandated for the Redirect SCA Approach, specifically when TPP-Redirect-Preferred equals "true". It is recommended to always use this header field.

Remark for Future: This field might be changed to mandatory in the next version of the specification.

TPP-Nok-Redirect-URI
string <uri>

If this URI is contained, the TPP is asking to redirect the transaction flow to this address instead of the TPP-Redirect-URI in case of a negative result of the redirect SCA method. This might be ignored by the ASPSP.

TPP-Notification-URI
string

URI for the Endpoint of the TPP-API to which the status of the payment initiation should be sent. This header field may by ignored by the ASPSP.

For security reasons, it shall be ensured that the TPP-Notification-URI as introduced above is secured by the TPP eIDAS QWAC used for identification of the TPP. The following applies:

URIs which are provided by TPPs in TPP-Notification-URI shall comply with the domain secured by the eIDAS QWAC certificate of the TPP in the field CN or SubjectAltName of the certificate. Please note that in case of example-TPP.com as certificate entry TPP- Notification-URI like www.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications or notifications.example-TPP.com/xs2a-client/v1/ASPSPidentifcation/mytransaction- id/notifications would be compliant.

Wildcard definitions shall be taken into account for compliance checks by the ASPSP. ASPSPs may respond with ASPSP-Notification-Support set to false, if the provided URIs do not comply.

TPP-Notification-Content-Preferred
string

The string has the form

status=X1, ..., Xn

where Xi is one of the constants SCA, PROCESS, LAST and where constants are not repeated. The usage of the constants supports the of following semantics:

SCA: A notification on every change of the scaStatus attribute for all related authorisation processes is preferred by the TPP.

PROCESS: A notification on all changes of consentStatus or transactionStatus attributes is preferred by the TPP. LAST: Only a notification on the last consentStatus or transactionStatus as available in the XS2A interface is preferred by the TPP.

This header field may be ignored, if the ASPSP does not support resource notification services for the related TPP.

Update PSU Data for consents

This method update PSU data on the consents resource if needed. It may authorise a consent within the Embedded SCA Approach where needed.

Independently from the SCA Approach it supports e.g. the selection of the authentication method and a non-SCA PSU authentication.

This methods updates PSU data on the cancellation authorisation resource if needed.

There are several possible update PSU data requests in the context of a consent request if needed, which depends on the SCA approach:

  • Redirect SCA Approach: A specific Update PSU data request is applicable for
    • the selection of authentication methods, before choosing the actual SCA approach.
  • Decoupled SCA Approach: A specific update PSU data request is only applicable for
    • adding the PSU Identification, if not provided yet in the payment initiation request or the Account Information Consent Request, or if no OAuth2 access token is used, or
    • the selection of authentication methods.
  • Embedded SCA Approach: The Update PSU data request might be used
    • to add credentials as a first factor authentication data of the PSU and
    • to select the authentication method and
    • transaction authorisation.

The SCA Approach might depend on the chosen SCA method. For that reason, the following possible update PSU data request can apply to all SCA approaches:

  • Select an SCA method in case of several SCA methods are available for the customer.

There are the following request types on this access path:

  • Update PSU identification
  • Update PSU authentication
  • Select PSU authorization method WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.
  • Transaction Authorisation WARNING: This method needs a reduced header, therefore many optional elements are not present. Maybe in a later version the access path will change.
