Recurring billing

Информация Извините, эта глава доступна только на английском языке.

Recurring billing used to charge money without user interaction. For example to charge subsequent amount of money from user's credit card for monthly subscription.

Информация Recurring billing only works with subsequent Payment Requests for specific user. First Payment Request has to be completed with user interaction described at Payment flow page

Recurring billing consists of three steps:

  1. Payment Request initialization described at Payment flow page
  2. Payment Request authorization with token
  3. Payment Request capturing
Информация After obtaining token, there is no need for new token obtaining each time, unless it has expired and has to be obtained again

Payment Request authorization with token

To authorize payment without user interaction, you have to make an API call to Recurring Billing API using token generated for recurring billing using Payment Request hash after initializing Payment Request

Please visit Recurring Billing API specification page to get list of required parameters as well as endpoint path and examples. Or use any of our libraries, which can be found on Libraries page.

Payment Request capturing

For user to be billed you need to capture Payment Request after authorization. To do so, you have to make an API call to Checkout API using Payment Request hash after initializing Payment Request

Please visit Recurring Billing API specification page to get list of required parameters as well as endpoint path and examples. Or use any of our libraries, which can be found on Libraries page.

Flow example

Step 1

First we need to create new Payment Request which we will automatically authorize and bill

Информация At that point token already has to be issued with first payment with user interaction

    "parameters": null,
    "status": "new",
    "gateway_key": null,
    "token_strategy": null
}

Step 2

Now you have to authorize Payment Request with issued_token for that user

Request
PUT /checkout/rest/v1/payment-requests/PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj/authorize HTTP/1.1
Host: checkout-eu-a.paysera.com

{
    "token": "vLUGdTtnDjQs7Yv0fjYQyYfG60m"
}
Response body
{
    "id": "PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj",
    "payer": {
        "email": "payer@email.com"
    },
    "authorization_url": "https://checkout.paysera.com/PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj",
    "price": {
        "amount": "10.00",
        "currency": "EUR"
    },
    "locale": "en",
    "business_id": "LcKB4rs-pNVLgQKxZTaGzfZRAuiQPuyE",
    "order_id": "12345447",
    "unique_identifier": null,
    "valid_until": null,
    "description": "Payment for goods on order 12345447 on the website https://shop.com.",
    "method_key": "card",
    "method_country": null,
    "accept_url": "https://shop.com/accept-url",
    "cancel_url": "https://shop.com/cancel-url",
    "callback_url": "https://shop.com/callback-url",
    "affiliate_key": null,
    "parameters": null,
    "status": "authorized",
    "gateway_key": "card",
    "token_strategy": null
}

Note, that Payment Request status is authorized, which means that Payment Request can be captured now

Step 3

To bill user, you have to capture authorized Payment Request, to do so, you have to make an API call to Recurring Billing API

Request
PUT /checkout/rest/v1/payment-requests/PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj/capture HTTP/1.1
Host: checkout-eu-a.paysera.com
User-Agent: Paysera WalletApi PHP library
Authorization: MAC id="wkVd93h2uS", ts="1343811600", nonce="nQnNaSNyubfPErjRO55yaaEYo9YZfKHN", mac="7I+B1M4FcfDqTRTc2Bvw+UMfkfKl6XG1J3F9nevp9XU="
Response body
{
    "id": "PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj",
      "payer": {
        "name": "John",
        "surname": "Doe",
        "email": "payer@email.com"
      },
    "authorization_url": "https://checkout.paysera.com/PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj",
    "price": {
        "amount": "10.00",
        "currency": "EUR"
    },
    "locale": "en",
    "business_id": "LcKB4rs-pNVLgQKxZTaGzfZRAuiQPuyE",
    "order_id": "12345447",
    "unique_identifier": null,
    "valid_until": null,
    "description": "Payment for goods on order 12345447 on the website https://shop.com.",
    "method_key": "card",
    "method_country": null,
    "accept_url": "https://shop.com/accept-url",
    "cancel_url": "https://shop.com/cancel-url",
    "callback_url": "https://shop.com/callback-url",
    "affiliate_key": null,
    "parameters": null,
    "status": "captured",
    "gateway_key": "card",
    "token_strategy": null
}

Not, that Payment Request status is captured, which means that Payment Request has been successfully processed and money was charged. You still need to wait for notification and mark it as read, to fully finish flow

Step 4

After payment captured we will send a notification_id in POST body(application/x-www-form-urlencoded format) to callback_url provided (ex. https://shop.com/callback-url will receive notification_id: O2qQQQQ-rWzLgQKxZTamdfZRApsrPuyE) Notification body example: 

notification_id=O2qQQQQ-rWzLgQKxZTamdfZRApsrPuyE

Then you have to either check what inside and mark that notification as read, or mark that notification as read in one call. We suggest you to check first and mark after, but it's up to you.

Request
GET /notification/rest/v1/notifications/O2qQQQQ-rWzLgQKxZTamdfZRApsrPuyE HTTP/1.1

User-Agent: Paysera WalletApi PHP library

Response body
{
  "id": "O2qQQQQ-rWzLgQKxZTamdfZRApsrPuyE",
  "event": "payment_request.captured",
  "status": "new",
  "data": {
    "id": "PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj",
    "payer": {
      "name": "John",
      "surname": "Doe",
      "full_name": "John Doe",
      "email": "payer@email.com",
      "account_number": "123456XXXXXX1234"
    },
    "authorization_url": "https://checkout.paysera.com/PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj",
    "price": {
      "amount": "10.00",
      "currency": "EUR"
    },
    "price_paid": {
      "amount": "10.00",
      "currency": "EUR"
    },
    "locale": "en",
    "business_id": "LcKB4rs-pNVLgQKxZTaGzfZRAuiQPuyE",
    "order_id": "12345446",
    "unique_identifier": null,
    "valid_until": null,
    "description": "Payment for goods on order 12345446 on the website https://shop.com.",
    "method_key": "card",
    "method_country": null,
    "accept_url": "https://shop.com/accept-url",
    "cancel_url": "https://shop.com/cancel-url",
    "callback_url": "https://shop.com/callback-url",
    "affiliate_key": null,
    "parameters": null,
    "status": "captured",
    "gateway_key": "card",
    "token_strategy": null
  }
}

As you can see you get notification data about Payment Request. Status is captured, that means that payment is successfully finished.
We provide additional information about payer such as name, surname, card number if those are available.

After processing data you have to mark notification as read, or callback will be repeated few times until you mark it as read.
To do so you have to make API call to Notification Event API

Request
PUT /notification/rest/v1/notifications/O2qQQQQ-rWzLgQKxZTamdfZRApsrPuyE/read HTTP/1.1
Host: checkout-eu-a.paysera.com

Response body
{
  "id": "O2qQQQQ-rWzLgQKxZTamdfZRApsrPuyE",
  "event": "payment_request.captured",
  "status": "read",
  "data": {
    "id": "PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj",
    "payer": {
      "name": "John",
      "surname": "Doe",
      "full_name": "John Doe",
      "email": "payer@email.com",
      "account_number": "123456XXXXXX1234"
    },
    "authorization_url": "https://checkout.paysera.com/PRAFY24n-UBgSkiRCL-h_CVAAvj4MEkj",
    "price": {
        "amount": "10.00",
        "currency": "EUR"
    },
    "price_paid": {
      "amount": "10.00",
      "currency": "EUR"
    },
    "locale": "en",
    "business_id": "LcKB4rs-pNVLgQKxZTaGzfZRAuiQPuyE",
    "order_id": "12345446",
    "unique_identifier": null,
    "valid_until": null,
    "description": "Payment for goods on order 12345446 on the website https://shop.com.",
    "method_key": "card",
    "method_country": null,
    "accept_url": "https://shop.com/accept-url",
    "cancel_url": "https://shop.com/cancel-url",
    "callback_url": "https://shop.com/callback-url",
    "affiliate_key": null,
    "parameters": null,
    "status": "captured",
    "gateway_key": "card",
    "token_strategy": null
  }
}

As you can see response is almost identical(that's why you can just read it without pre-reading) as when just getting notification data, except that this time status is read, that identifies that no more callbacks about this notification will be sent from our system
