For Allowed JavaScript origins (field)

In this field, you’ll enter the full URL of your live website where Amazon Pay buttons or checkout might be used. This is a security measure that allows Amazon Pay to work only on authorized domains.

Make sure to use https:// (Amazon Pay requires a secure site)

Do not include any slashes at the end (e.g., /)

Allowed Return URLs (field)

The Allowed Return URLs field tells Amazon Pay where to send the customer after they complete or cancel a transaction. This should point to your store’s checkout success or order confirmation page.

Important Notes:
