Cancel (Void) transaction API is used to cancel (void) the transaction with PG. Usually, this API can get the transaction cancelled (voided) when transaction is still in non-terminal state i.e. PROCESSING, AUTHORIZED, CAPTURED, PROCESSING. It supports cancellation of AUTH, PURCHASE, CAPTURE and REFUND transactions. Based on the transactionUtr provided in the request, checkout will identify which transaction needs to be cancelled.
