Checkout Session
A Checkout Session represents a single active session (or engagement) for a buyer on your website. The Checkout Session can be used to facilitate a one-time charge, multiple charges, or recovery from a declined payment.
The Checkout Session starts in the Open state. In the Open state, you can use the Checkout Session to retrieve checkout details such as shipping address, and set relevant payment details such as total order amount. You can also use the Checkout Session to either charge the buyer immediately, or exchange it for a Charge Permission that can be used to charge the buyer later.
The Checkout Session moves to the Completed state after you call Complete Checkout Session if transaction processing was successful. In the Completed state, you can use the Checkout Session to retrieve references to a Charge Permission and also a Charge if payment authorization was requested.
The Checkout Session moves to the Canceled state after the Checkout Session has been in the Open state for 24 hours or if transaction processing failed. In the Canceled state, you can use the Checkout Session to retrieve why checkout failed.
Note that Amazon Pay permanently deletes Checkout Session objects and any associated information after 30 days.
