I am trying to use the Express API operations such as TokenCreate and PaymentAccountCreate (XML, not SOAP). However, when I make these requests I get a response code 103 with this message:
The 'https://transaction.elementexpress.com:TokenCreate' element is not declared.
or this message:
The 'https://transaction.elementexpress.com:PaymentAccountCreate' element is not declared.
I attached an example of a request I made, with a few fields blocked out. Any idea what I am doing wrong? Are there any examples for these requests?
