Refund with original split ratio

Split a refund between the balance accounts in your platform, according to the original payment's split ratio.

Limitations The full refund amount is debited from your liable balance account by default if:
  • The payment authorization did not have split instructions.
  • The refund is partial.

Get the TransactionID and the TimeStamp of the original payment. You received these values in the payment response, in the POITransactionID object.

Refund request

Here is an example Terminal API request to split a refund of EUR 620.00 according to the original payment split:

The refund request is routed to the terminal, where the customer can present their card. The payment terminal shows a waiting screen until you receive a response.

Refund response

When you receive the ReversalResponse, check if we received your request. Note the following:

  • Response.Result: Success. This means we received your request. The refund itself will be processed asynchronously.
  • POIData.POITransactionID.TransactionID: the PSP reference for this refund request.
  • PaymentReceipt: the generated receipt data. This includes REFUND REQUESTED.

  • Response.AdditionalResponse with:

    • posOriginalAmountValue: the amount (in minor units) of the original payment.
    • posAuthAmountValue: the refund amount (in minor units) that we will try to get authorized.

    • pspReference: the PSP reference for this refund request.

Troubleshooting

If your request failed, the ReversalResponse contains:

  • Response.Result: Failure

  • AdditionalResponse: this includes a message explaining why the request failed. For example:

    • Original pspReference required for this operation: messages like this tell you how to fix the request so you can try again.
    • Transaction is already voided: this message tells you that we already received a full reversal request for the original transaction.

Webhook

Wait for the CANCEL_OR_REFUND webhook to learn the outcome of the refund request. Refunds are always processed asynchronously.

The following tabs show the webhooks you receive when:

  • The payment amount is deducted from your user's balance account
  • The commission amount is deducted from your liable balance account
  • The transaction fees are deducted from the specified balance account
