View source for X-Payments:Capture, Void and Refund via the X-Payment Order State tab when using X-Payments with Magento

If your store's workflow does not involve invoicing, or you are dealing with an X-Payments order that has previously been edited using Magento's default Edit feature, you can perform Capture, Void and Refund operations via the X-Payment Order State section of the order details (The section can be accessed by clicking the '''X-Payment Order State''' tab in the '''Order View''' menu). The specific operations available to you depend on the current order state, and you can only see the buttons for the operations that you can perform. If necessary, you can edit the amount on which the operation is performed by editing the contents of the iput field in the Actions column of the table.

'''Important''': If you have already performed a Capture, Void or Refund operation on an order via the X-Payment Order State section, you should not attempt to do any further payment related operations on this order using the online options of the invoice (like Invoice: Cancel, Invoice: Capture Online or Invoice: Credit Memo→Refund Online), as it may cause the following problems:
* Sending a duplicate request for the current transaction;
* Requesting a transaction for an unavailable amount (For example, by doing Invoice: Credit Memo→Refund Online you may be requesting a refund for an amount exceeding the amount that you have captured originally via the '''Order(s) state''' block in the X-Payment Order State section).
The opposite is also true: If you have used on a certain order a payment related operation based on an online option of the invoice (Invoice: Cancel, Invoice: Capture Online or Invoice: Credit Memo→Refund Online), do not attempt to perform any further payment related operations on this order via the X-Payment Order State section, as it is likely to cause similar problems.
