I forgot to authorise or decline one of my PayTo agreements. What happens now?
You will have up to 5 calendar days (or another timeframe determined by the Payee) to authorise or decline a new PayTo agreement or amendment request. If the expiry date and time for the request has passed, the PayTo agreement will change to the status Authorisation Timed Out.
If you are authorising a new request in person, the request will only be visible for up to 5 minutes.
