Together with 'Approve' and 'Decline' responses, a payment gateway may return 'AuthCall' response. Possibility of the latter response depends upon your personal arrangements with processing center. In Parallels Business Automation - Standard, the Authorize.Net Plug-in supports this. Parallels Business Automation - Standard Dummy payment Plug-in (that can be used for trial purposes) can be directly set to 'Always Auth Call' as a transaction-result response, so you can try, how it will work (in this case, you can submit an arbitrary authorization code).
The figure below shows you the details of the Waiting for Auth Call Order (the Dummy payment plug-in was selected) and where you can find and submit the needed authorization codes..
The list of 'Waiting for Auth Call' Orders may include both renewal and new Orders that were suspended by a payment gateway "Auth Call' response. 'Auth Call' means that in order to finish a transaction, you need to look in Order details and found the Authorization code. Thus, to finish transaction, click on Order ID. Look in Transaction Details section (see the figure above) for authorization code. If needed, look in the Transaction log to get the transaction reference number.
Call to Online Processing Center and submit your authorization code. After this, you will be provided with another authorization code from Online Processing Center. Type this or paste code in Authorization Code textbox and click the Submit Code button. After this, a transaction will be finished.
In general, buttons below the 'Waiting for Auth Call' Order details allow doing the following:
Note: Not all plug-ins support the AuthReversal transactions, i.e., cancelling the transaction on the Preauth stage (when the amount was reserved and the transaction was suspended till authorization). If a plug-in used to pay a document does not support the AuthReversal transactions then both the Decline Transaction and Decline transaction and Cancel Order buttons will not be shown.
If a transaction was finished successfully, a charged Order will move to 'Waiting for Processing' list and you can allow creation of appropriate Subscription, i.e., provide services to a customer.
