Integrate directly with our REST APIs from any language:

curl -X POST https://api.paysera.com/merchant-order/integration/v1/orders \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "purchase": {
      "reference": "ORDER-123",
      "amount": 1000,
      "currency": "EUR"
    },
    "redirect_urls": {
      "success_url": "https://your-site.com/success",
      "failure_url": "https://your-site.com/failure",
      "callback_url": "https://your-site.com/webhook"
    }
  }'

Amount Format

All amounts use minor currency units: "1000" = €10.00
