# Retry Notification

Your `Notification URL` must response with HTTP status `2xx` to confirm the transaction notification is received. 

If your URL doesn't respond with this status, we'll make 3 attempts to deliver the HTTP Notification. We'll stop retrying once we receive a response from your server or if there's still  no response.
