Manage Payments Using Saved Wallet

[Step 4 of 9] After the buyer has successfully completed setup of Saved Wallet, the Complete Checkout Session response will include a ChargePermissionId for a Saved Wallet Charge Permission object that you can use to charge the buyer and manage cancellations.

At the end of this step, you will be able to charge the buyer and manage cancellations.

1. Managing charges and handling declines
2. Managing cancellations
3. Changing the Payment Method
4. Saved Wallet Expiration

1. Managing charges and handling declines

Call Create Charge each time you need to charge the customer. Set CaptureNow to true to capture payment immediately, set it to false to capture later. Note that Amazon Pay limits how much you can charge the buyer for each calendar month, see monthly Saved Wallet charge limits for more info.

If Create Charge returns a 201 response, authorization was either successfully completed or successfully initiated depending on whether canHandlePendingAuthorization was set to true. If Create Charge returns a different HTTP status code, check the request response reasonCode to determine if you should retry Create Charge or ask your buyer to use a different payment method:

If reasonCode is SoftDeclined or ProcessingFailure:
1. Call Get Charge Permission to confirm that the Charge Permission is in a Chargeable state
2. Call Create Charge to charge the buyer
If reasonCode is HardDeclined, ask the buyer to update their payment instrument using the following link: https://payments.amazon.com/jr/your-account/ba/{ChargePermissionId}. Replace {ChargePermissionId} with the buyer's Charge Permission Id. Set up IPNs to receive a notification once the payment instrument has been updated and then:
1. Call Get Charge Permission to confirm that the Charge Permission is in a Chargeable state
2. Call Create Charge to charge the buyer

2. Managing cancellations

Use Close Charge Permission to inform Amazon Pay if a buyer cancels/removes their Saved Wallet. You will no longer be able to charge a buyer unless they consent again to setup Saved Wallet.

Buyers can also close Charge Permissions by signing in to https://pay.amazon.com. Set up IPNs to receive notifications whenever a Charge Permission is closed. To minimize churn, we recommend that you proactively reach out to the subscriber for a new payment method before the next billing cycle.

3. Changing the Payment Method

Buyers can update their payment method on Saved Wallet from https://pay.amazon.com section of the Amazon Pay website. Any subsequent charges are processed using the updated payment method. The payment method associated with any previous charges are not updated. A direct link can also be provided to the buyer to allow easy updates of associated payment method using the following URL: https://payments.amazon.com/jr/your-account/ba/{ChargePermissionId}. Replace {ChargePermissionId} with the buyer's Charge Permission Id.

4. Saved Wallet Expiration

Charge Permissions with a type of paymentMethodOnFile do not have a set expiration and will persist until closed.
