Login and pay with Amazon integration issue

Question

So, I'm trying to integrate the Login and Pay with Amazon widget, and I'm encountering some problems.

So, I have my seller account all set up on

https://sellercentral.amazon.de/gp/

I have access to my API credentials, and I need to get a LWA client. So, I have registered on

https://sellercentral.amazon.com/gp/homepage.htm

in order to create an application. I have set up the application, on web settings I have completed the required URL's, and got my client ID.

In the js for the Login and Pay with Amazon widget, I have replaced all the info needed: Client Id, merchant Id etc. But when I try to make a test login, I receive the following error :

400 Bad Request Unknown client_id

The Pay With Amazon documentation is not very clear, and I can't seem to find anywhere a list with the error codes.

If anybody has an idea, let me know. Thanks!

Answer 1

you should create your Login with Amazon application using https://sellercentral.amazon.de instead of the .com site. They are separate accounts.

Answer 2

听起来您好像缺少了这段代码：

window.onAmazonLoginReady = function() { amazon.Login.setClientId('CLIENT_ID'); }
