Authorization Reversal

This section provides the information about how to process an authorization reversal.
Reversing an authorization releases the hold on the customer’s payment card funds that the issuing bank placed when processing the authorization.
For a debit card or prepaid card in which only a partial amount was approved, the amount of the reversal must be the amount that was authorized, not the amount that was requested.

Supported Card Types

All supported card types can process reversals.
