  • All the parameters marked required must be filled to enable the Generate Hash button.
  • The example listed (like a cookie) in each parameter field is for reference purposed only, so it is suggested to type the values similar to the listed example.
  • Use only the the test card numbers, test UPI handle, test wallet, etc. in API Reference, refer to Test Cards, UPI ID and Wallets.
