I noticed when I don't include a return url when doing the transaction setup, that the response from process transaction to the hosted payments page includes a type named "args" with what appears to be encoded text. Can you tell me what this is and if it can be used for something? Sample below. Thanks.
The additional args data returned cannot be used, and I believe are only being included when the Embedded tag is set to True (1), but where no ReturnURL value is included. It's obviously not required, but when Embedded is set to True (1), we recommend always using a valid ReturnURL.
