Online Payments?

I just want to know if there is a way to make payments on the Easy Pay system for hotels via the internet. The "payment portal" link on the app and the mobile site will not let me log in, even though I'm entering correct information. No one I've spoken with on the phone has given a straight answer. All I need to know is if it's possible to make payments on the actual website. If so, can someone send me a link? Thanks.

The last time I checked, you have to call the central reservations number to make a payment.
