Method: setAcquirerReferenceNumberForRefundNotification

Notifies Google of the Acquirer Reference Number (ARN) for a refund.

The acquirerReferenceNumber value is unique for this refundRequestId and cannot be changed by a subsequent call to this method. If a new request is made with a different ARN for the same refundRequestId an HTTP 400 will be returned.

This is used to inform Google for the ARN for this refund. This is an identifier that is shared between the issuer, merchant, network and processor. It typically is known to the processor a few days after the refund request was made. Providing this value for a refund helps Google correctly handle requests involving the refund.

If the echo is successful, the endpoint will return an HTTP 200 and the response will be of type [EchoResponse][google.standardpayments.flows.diagnostic.v1.EchoResponse].

If the endpoint encounters an error while processing the request, the endpoint will return HTTP 4xx or 5xx and the HTTP body will either be of type ErrorResponse or contain a generic error (e.g. a message similar to "There was an error. Please try again later.").

The generic error is used in situations where an ErrorResponse with a clear description could be used to help an attacker understand the payment integrator account identifier of other integrators. In these situations, where either the signing key doesn't match, the payment integrator identifier was not found, or the encryption key was unknown, this method will return a generic error. If the request signature could be verified, additional information regarding the error will be returned in an ErrorResponse.

An example request looks like:


{
  "requestHeader": {
    "protocolVersion": {
      "major": 1,
      "minor": 0,
      "revision": 0
    },
    "requestId": "b7256a33-864d-40cb-84be-7ad2482cf25a",
    "requestTimestamp": "1482797086000"
  },
  "paymentIntegratorAccountId": "SpeedyPaymentsIndia_INR",
  "refundRequestId": "G18FCDTLD5B0SR4",
  "acquirerReferenceNumber": "74896130957836587146723"
}

An example response looks like:
