AuthOnly Method
Initiates an authorization-only request transaction.
Syntax
int AuthOnly();
Remarks
This method sends an authorization-only request to the specified Gateway. This transaction is not added to the current open batch, and must be completed later with the Capture method (you may use the Sale method if you wish to authorize and capture in one step).
Note: If the Gateway does not support this method, the class will fails with an error.
Error Handling
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
