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
I have access to my API credentials, and I need to get a LWA client. So, I have registered on
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!
you should create your Login with Amazon application using https://sellercentral.amazon.de instead of the .com site. They are separate accounts.
