How to cancel a UPI payment in Paytm?

It is generally not possible to cancel a successful UPI payment once you have entered your UPI PIN. UPI transactions are designed for instant fund transfers and are irreversible. If you have sent money to the wrong person, you should contact the recipient and request a refund. If they refuse, immediately contact your bank's customer support or use the help section in the Paytm app to report the issue. For recurring payments, you can cancel future debits by managing your UPI Autopay mandates in the app settings.
