How to test stored credentials?

[#1]

so with the Vantiv Hosted Payments - Process Transaction endpoint, is there a way to test the PaymentAccountQuery method and get credentials back?

Hi Alex, the PaymentAccountQuery method resides on our Services interface (https://certservices.elementexpress.com/).

I haven't seen any references to multiple end points or namespaces in the Vantiv Express Interface API v2.9.2 document. Maybe I've missed something, but it should really be mentioned in the section for each method, because you will typically implement one method at a time using those pages as the reference.
