AuthOnly Method

Sends an AuthOnly transaction to the host.

Syntax

 int AuthOnly();

Remarks

An Auth Only transaction is used to verify and reserve the cardholder's open-to-buy funds available at that time. This transaction is NOT added to the open batch. In order to settle (be paid) for this transaction, the merchant must run a Capture transaction using the original ResponsePNRef obtained during this Auth Only transaction. Only then will the transaction be added to the open batch. Typically any funds blocked with a Sale or Auth Only transaction are reserved for approximately seven (7) to ten (10) days. This may vary from issuer to issuer. Sample transactions follow.
