How do I link my bank account to UPI?

To link your bank account to UPI using a UPI-enabled app like Paytm, open the app and go to 'UPI & Payment Settings'. Tap on 'Link Bank Account' or 'Add a Bank Account' and choose your bank from the list. The app will verify your mobile number linked to the bank account via SMS. Once verified, your bank account is linked, and you may be prompted to set up a UPI PIN using your debit card.
