The 400 code is a generic one for Bad Request, but Amazon usually sends more information in the response itself. If the page in the uri_direct is one you own and can modify, you can try to add code to it to show the message that's sent in the response.

Hi there, Thanks for the post. We recently launched some granular scopes to choose when requesting access to customer accounts for reading content. Older apps created before this feature was implemented can still use the cloud drive:read scope whereas new app developers must use the new scopes. For more information, see here: https://developer.amazon.com/public/apis/experience/cloud-drive/content/getting-started Regards, Jamie

I whitelisted the following url : https://roscasend.go.ro/ and ì used for redirect_uri the following url https://roscasend.go.ro and for that reason I encountered the bad request error. I updated the redirect_uri to be the same as the allowed origin url from the web settings tab of the security profile and it worked.
