URI Whitelist Error

Hi Guys, I’ve installed Amazon Payments on my Shopify store, however when i test the Amazon payment checkout I get this error:

Error Summary
400 Bad Request
The redirect URI you provided has not been whitelisted for your application. Please add your redirect URI in the ‘Allowed Return URLs’ section under ‘Web Settings’ on the Amazon Seller Central App Console for Login with Amazon.

I can’t find the ‘web settings’ anywhere in the sellercentral.amazon.co.uk app. Any ideas how I can correct this error?

Thanks

To resolve the error you’re encountering with Amazon Payments on your Shopify store, you’ll need to follow these steps:

  1. Log in to your Amazon Seller Central account at sellercentral.amazon.co.uk.
  2. From the main dashboard, click on “Apps & Services” in the top menu.
  3. Select “Login with Amazon” from the drop-down menu.
  4. On the Login with Amazon page, click on the “Manage” button for your application.
  5. Under the “Web Settings” section, you should find the “Allowed Return URLs” option.
  6. Add your redirect URI, which is the URL where Amazon Payments will redirect your customers after completing the payment process. Make sure to enter the exact URL used in your Shopify store.
  7. Save your changes.

Once you have added the redirect URI to the “Allowed Return URLs” section, the error you encountered should be resolved. You can then test the Amazon payment checkout again to ensure it’s working correctly.

If you are unable to find the “Web Settings” section or encounter any further issues, I recommend reaching out to Amazon Seller Support for further assistance. They will be able to guide you through the process or provide specific instructions based on any recent changes to the Amazon Seller Central interface.
