Is it possible to cancel a UPI transaction

Once you enter your UPI PIN and complete a transaction, it's generally not possible to cancel it. It's like sending a letter – once it's in the mail, you can't get it back!\n\nIf you accidentally sent money to the wrong person, the best thing to do is contact the person you sent it to and politely ask them to send it back. If that doesn't work, you can always reach out to your bank for help. They might be able to guide you on what to do next.
