Can anyone please upload a video tutorial for this, as I am unable to perform it.

1. Try booking a flight via smartbuy. Reach the payment page (same-thing works with cash conversion)
2. View source of that page.
You need to confirm resubmission.
Search for JS function ‘getcustomerpoints()’. Copy it. Replace the variable for reward redemption (response.points_percentage) to your dummy variable. Give it value of 2 so rewards essentially doubles.
3. Paste the updated function in the console. Run getcustomerpoints()
4. Now when you move sliders it will show updated value. You can generate OTP. Transaction details would show up in Network tab.
5. It will reduce the amount by 2x, but HDFC has clearly mentioned they can charge the card in case of discrepancy.
(also, not sure for how long this will be valid now)
Have fun!?
