Adding the Amazon Pay Button Widget

These widgets help to create the Billing Agreement. Detailed instructions on how to set up the widgets on your site can be found here.


Login Widget

The user clicks this button to login to Amazon. After successfully logging in, the next widgets can be rendered.


Address Book and Wallet Widget

The user selects a shipping address which is stored in the Billing Agreement. If you do not want to use this widget, refer to this article for more information. If not, then after the user selects an address from the AddressBook, the Wallet widget can be rendered

With this widget, the user selects a payment method that will be stored in the Billing Agreement. LimeLight will not be able to access information about this payment. Instead, we will use a token that is generated at the end of the user flow to authorize and capture on payment methods.


Repeat Payment Authorization Widget

This is the final widget in the user flow. It collects the user’s consent for recurring payments, and if it is not checked, then recurring payments will not be possible.


Amazon Instant Payment Notification Messages (IPN)

LimeLight has enabled the use of Amazon Pay IPNs to notify you if a payment has been refunded successfully. Follow these steps to take advantage of this feature and start receiving updates regarding refunds. Once enabled, LimeLight will receive the necessary information to update the refund transaction status.
