(1) For Non-BBPS CC billers (like Amex or SC), you cannot use SBI Unipay and most other apps. You can load Amazon wallet or payzapp wallet using debit cards which give points on Wallet load (like HDFC Millenia) and pay using the bill desk website. Alternatively, you can use cc issuer NEFT/UPI details as well.

In this thread it is mentioned that we can load amazon wallet using HDFC millennia debit card and then pay AMEX bill in bill desk using wallet. But in billdesk I don't see an option to use wallet! I'm using this site - https://www.billdesk.com/pgidsk/pgmerc/amexcard/amex_card.jsp
it only shows, netbanking and UPI as options
Anyone know how to pay amex bill using amazon wallet?
