The Acquiring Service Provider(ACQP) can refund a payment by using the refund API or the Alipay+ Partner Workspace. The refund service is only applicable to a transaction that has been successfully paid.

The following table introduces more information about the refund service that is provided by Alipay+:



Refund expiration period

You (the ACQP) can invoke a refund any time after the transaction is successfully paid and before the refund period expires. The refund expiration period is one calendar year, starting from when the initial payment is made. However, if the original payment was successfully canceled, you cannot initiate a refund request. The refund request cannot be revoked once initiated.

Refundable amount

Alipay+ supports full refunds, partial refunds, and multiple partial refunds. For a single transaction, the total amount of multiple partial refunds cannot exceed the original amount paid by the user.

Currency conversion

A transaction is refunded using the same Foreign Exchange Rate as when the transaction is paid.

Fee items and settlement

After a refund succeeds, the interchange fee (also known as the interpartner fee) is refundable, while the service fee is non-refundable. After Alipay+ processes your refund request, the refund is settled in real-time by transferring funds from your credits to the payer's digital wallet or bank card. Refund transactions are included in the clearing and settlement files. Note that the current policies on fee items are subject to adjustment according to Alipay+ Core Rules.

Refund methods

If you want to refund the payment through the refund API, see Call the refund API for instructions. If you want to refund the payment through Alipay+ Partner Workspace, see Refund payment on Alipay+ Partner Workspace for instructions.

Call the refund API

You can call the refund API to refund a payment. You can confirm whether the refund succeeds by the synchronous result returned by Alipay+.

Processing logic

When using the refund API, you need to take the following things into consideration:

  • The parameter refundRequestId is idempotent and must be unique.
  • The value of the refundAmount parameter, or the total value of the refundAmount parameters in multiple partial refund requests, cannot exceed the value of the paymentAmount parameter in the pay API request.
  • You might receive different results from Alipay+, follow the instructions below to handle the result:
