Reserves a specified amount against the payment methods stored in the order reference.


The Authorize operation reserves a specified amount against the payment methods stored in the order reference. 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.

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.

This API call is idempotent. If called multiple times, with unchanged parameters (including AuthorizationReferenceId), the same result is produced.

Parameter name Description

  • lowercase a-z
  • uppercase A-Z
  • numbers 0-9
  • dash (-)
  • underscore (_)
Maximum: 32 characters

A description for the transaction that is displayed in emails to the buyer. Appears only when CaptureNow is set to true.

Maximum: 255 characters

The maximum number of minutes allocated for the Authorize operation call to be processed, after which the authorization is automatically declined and you cannot capture funds against the authorization.

Note: In asynchronous mode, the Authorize operation always returns the State as Pending. The authorization remains in this state until it is processed by Amazon. The processing time varies and can be a minute or more. After processing is complete, Amazon notifies you of the final processing status. For more information, see Instant Payment Notification (IPN) in the Amazon Pay and Login with Amazon integration guide.

Valid values: Zero or integer values in multiples of five (5, 10, 15, etc.). Set the value to zero for synchronous mode. Set the value to greater than zero for asynchronous mode.

TransactionTimeout values in synchronous mode:
  • Must be 0
TransactionTimeout values in asynchronous mode:
  • Minimum: 5
  • Maximum: 1440
  • Default: 1440

Indicates whether to directly capture a specified amount against an order reference (without needing to call Capture and without waiting until the order ships). If set to true, specify the SellerAuthorizationNote. The captured amount is disbursed to your account in the next disbursement cycle.

Note: The Amazon Pay policy states that you charge your buyer when you fulfill the items in the order. You should not collect funds before fulfilling the order.

Allowed values:
  • false--To capture the funds specified in this authorization, you must call the Capture operation.
  • true--The specified amount is directly captured. You do not need to call the Capture operation.
Default: false

The description to be shown on the buyer's payment instrument statement if CaptureNow is set to true. The soft descriptor sent to the payment processor is: "AMZ* <soft descriptor specified here>".
