Best options for cc payment?

Use Sbi Unipay and Idfc dc if you have

I use  FI account. Fetches 2% CB ( Max 500₹)

And you also get 20% FI coins on debit card spends and 10% coins via UPI spends.

In a year, I redeem around 6.5K-7K worth of coins as Amazon voucher.

Minimum Balance needed is 50K

Other than the debit card cashback for credit card payments, is there any site or app that still gives a flat cashback on credit card payments? I was hearing about Snapay, but I don't find any offers

Has hdfc platinum dc offer ended ?

400 rs every month by paying cc payment 

If you don't want to get into waiting for 60-90 days for Cashback mess, you may also open Jupiter account and pay CC bill via UPI/Debit card and get 5X Jewels ( 1% cashback)

Max Limit is 100₹ for UPI and 150₹ for Debit Card.
