Credit Card payments on Bill Management

Hi all,

Can someone please help me with the below details?

Is there a list of supported payment service provider which can be used for credit card payment through bill management?

Any documentation/white paper that can help us understand the detailed steps as well as pre-requisites? I have reviewed the document:

PaymentGatewayIntegration.pdf. This document mentions about CyberSource only.

Thanks in advance for the help!
