Create an A2A refund


Please note that a new feature called Payment account has been introduced to simplify the refund process.

Here's how you can initiate a refund for a transaction that was previously initiated without a Payment account.

Step 1: Get the Payer's IBAN

Call the following endpoint to obtain the IBAN of the payer:

  "id": "e959dccd632c49d7922a766e946ad9e9",
  "status": "ACSC",
  "user": {
    "name": "Firstname Lastname",
    "external_reference": "AEF142536-890",
    "ip_address": ""
  "sender": {
    "name": "John doe",
    "iban": "FR183490204820028402" // <------ Get this value
  "transactions": [
      "amount": 99.5,
      "currency": "EUR",
      "label": "Payment label",
      "id": "79e61d0c29b1491196bc0c39f27b5bb8",
      "status": "ACSC",
      "beneficiary": {
       		"first_name": "Test",
        	"last_name": "Name",
        	"iban": "FR2310096000301695931368H67"
      "client_reference": "12345678-AZERTY"

Create a payment-request (Amount of refund, label of refund, IBAN of payer retrieved in the previous step, Bank id of the merchant account).

Step 2: Create a Payment Request

Create a payment-request with the following details:

  • Amount of refund
  • Label of refund
  • IBAN of the payer (retrieved in the previous step)
  • Bank ID of the merchant account

Step 3: Redirect to the consent_url

Read the value of the consent_url attribute generated in step 2 and redirect the merchant accordingly.


Contact your Account manager

To access the non-obfuscated IBAN of the payer, please reach out to your Account Manager. If eligible, your Account Manager will grant this capability to your app.
