OAuthException Application error code 50

    Best answer by José.Deezer

    Hello, this was the decision of the team responsible for management of the API.

    Some users are in breach of the terms and conditions when they sign the contract to use our API, https://developers.deezer.com/termsofuse.

    In other cases, Deezer don’t have visibility on the usage of our API.

    So, based on the findings, some cases we have manage to reinstate the APP ID, but other cases, we left the APP ID deactivated.

    Again, if we have miss judge any case, as said above, we would require evidences how the API is being used, sharing website links or applications, ... 

    Apologies for the less positive news.

    Jason here. I can report the same issue with my app. The login flow does successfully give me a token, but I cannot access the /me/playlists endpoint or any other /me endpoint that requires auth. This issue started over the weekend. I’ve been using the API for ~1 year without issue for about 100 authenticated users. None of my code changed, the error appeared out of the blue.

    `{ type: 'OAuthException', message: 'Application error', code: 50 }`

    Does this information somehow reach the developers?

    Thanks ​@dsander for sharing your case. Already DM you and now let's wait for feedback from our developers.

    If new cases arise on this thread, please DM me with the app_ID of your application and name, to make the process more efficient.

    For context, this could be connected with a batch of unused app_ids we have recently disabled, as we were not getting any calls from those IDs. So we are investigating our cases.

    Again, many thanks for your understanding and hope to have things sorted soon.
