How do I cancel a PayPal order or authorization?
If you need to cancel a PayPal order or authorization on your account, please contact the merchant directly. An order or authorization is an agreement between you and the merchant to purchase an item for a set amount, and PayPal doesn't have the ability to cancel that agreemeent.
Orders and authorizations typically expire in 30 days.
Authorizations can also be placed for a future purchase, for example a hotel stay or reservation. This type of authorization would not be processed until you arrive.
