Looks like you are passing the application ID as your token. You need to use the client ID to acquire an Oauth token as described here…
Also, has your Application been onboarded to allow access? your application ID would have to be enabled by Amazon Music before you will be able to access the API
Hi, I have the same problem as Jeremy and I think it’s because of what you said of having to enable my application ID by Amazon Music. Could you explain how to do it or where can I find that information?
Thank you
Hi Martha, we are currently limiting our beta for the APIs. you can send a request in using the ‘contact us’ form select Music Developer and Business opportunity. and we will let you know as we expand the beta pool.
