To void a pre-auth deposit transaction, the merchant has to post a request using the below parameters. The parameters have to be sent using the same encryption as the previous scenarios. Refer to Encryption section. The void endpoint returns the same EPG response that we use for the status URL. Bear in mind that a transaction is either left in a pending status (pre-authed) or automatically captured depeding on the business rules and logic set within the EPG back office. In other words, this is not determined by an api call but by rules. Send a POST request to the /void endpoint to void a pre-auth transaction.
