SoundCloud Public API

First create app credentials via Get an API key. For user-delegated access, send the user to https://secure.soundcloud.com/authorize with your client_id, registered redirect_uri, response_type=code, PKCE code_challenge, code_challenge_method=S256, and state, then exchange the returned code at https://secure.soundcloud.com/oauth/token as documented in the API Guide. For app-only public-resource access, exchange your app credentials for a token with the client credentials flow at the same token endpoint. Use the returned access_token in API calls; refresh with the documented refresh token flow when applicable.
