Voiding a Transaction

POST https://gateway-api.paycertify.com/api/transactions/{transaction_id}/void

A void is only possible after a transaction has been created through auth request. Once that’s done, you should use the transaction ID response field to reference the transaction being voided. A void simply cancels a previously made authorization and releases the authorized balance on the customer’s card.
