Refund transaction API is used to raise the refund transaction with PG. It supports partial as well as full refund. While doing create transaction, refund configurations need to be provided i.e. PARTIAL or FULL. In case of full refund, no duplicate refund transaction request will be allowed unless previously created refund transaction has failed. Generally, post settlement of the transaction, this API can be used to request for refund of partial amount or full amount. In case of AUTH-CAPTURE transaction, total amount that can be refunded should be equal to less than total captured amount.
Transaction Idempotency
If appUtr is present in the API request, then the refund transaction will be made idempotent. If another refund transaction is requested with the duplicate appUtr, then API will reject the refund transaction.
