Under what circumstances will responses to OnErrorUrl and OnDeclineUrl be used?
Based on the naming convention I would assume that OnDeclineUrl would be used when a credit card is declined, but I have seen some results where OnErrorUrl is used with the parameter: "on=Decline". Is there are logical set of rules that can be used to determine which callback URL will be used?
I have also noticed that the postback parameters to the callback URLs are varied. For example, I have seen responses to OnErrorUrl with the "on" parameter, and others with the "err" parameter. It would be helpful to know under which circumstances the varying parameters will be included, so that I can use the appropriately on my callback pages.
Thank you!
