Most Cash App payments are completed instantly and can’t be canceled. To find out for sure, check the activity section of your Cash App to see if the payment receipt is showing a cancel option. If there isn’t one, that means the recipient has already received the money and the payment can't be canceled.
The recipient can refund the payment – instruct them to locate your payment in their Cash App activity, and select the option to Refund.
Requesting a payment back for the same amount is also a simple way to receive the funds back. To request a payment with the Cash App, enter a dollar amount and tap Request.
