It seems so stupid that this is not already available.
If you have an ARB subscriber for a service you are offering on a monthly basis, you would of course want to know, often and simply, if that subscriber has paid his last bill before you continue to service him.
But instead of a simple API function, I have to parse through mountains of data and, if I dont want to have to do this everytime someone logs in ( to check if they should be able to), i also now have to create a database table to track this status and when it was last checked.
Please Authorize.net, create a simple API to do this simple check!!!
