Please don't test your biller setup with E-Pay Company's test account—it won't work correctly.
Setting up on E-Pay Company's Website
Register for an E-Pay Company account. Record your Affiliate ID.
Note: E-Pay Company provided a NATS setup document.
Go to the E-Paycompany Admin, find the Pay System Settings, and click the Set Websites link. Enter the following URL into the Control URL field.

Replace linkdomain with your linkdomain.
You can enter two URLS in the Control URL field. One URL is the Postback URL you just entered; the other is a redirect to your members area. Separate the URLS with a pipe character ("|"). Do not put spaces between the two URLS and the pipe.
Record the Site ID of every site you setup.
