Reserves a specified amount against the payment methods stored in the billing agreement.


The AuthorizeOnBillingAgreement operation reserves a specified amount against the payment methods stored in the billing agreement. To charge the payment methods, you must either set the CaptureNow request parameter to true or call the Capture operation after you call this operation. An authorization is only valid for a particular time period, which is specified in the response of the operation. At the end of the time period, the authorization expires and a notification is sent to you if you have set up Instant Payment Notifications (IPNs). For more information about Instant Payment Notifications, see Instant Payment Notification (IPN) in the Amazon Pay and Login with Amazon integration guide. You can also query the details about an authorization by calling the GetAuthorizationDetails operation.

Note: This is a convenience operation that creates and confirms an Order Reference object, requests an authorization, and then closes the order reference.

This operation has a maximum request quota of 10 and a restore rate of one request every second in the production environment. It has a maximum request quota of two and a restore rate of one request every two seconds in the sandbox environment. For definitions of throttling terminology and for a complete explanation of throttling, see Throttling: Limits to how often you can submit requests in the Amazon MWS Developer Guide.
