The Client Credentials flow is used in server-to-server authentication. Only endpoints that do not access user information can be accessed.

ClientCredentialsFlow clientCredentialsFlow = new ClientCredentialsFlow();
String accessToken = clientCredentialsFlow.getClientCredentialToken(
        "CLIENT ID",
        "CLIENT SECRET")
        .getAccessToken();

SpotifyApi spotifyApi = new SpotifyApi(accessToken);

AlbumFull albumFull = spotifyApi.getAlbum("ALBUM ID");

This flow is suitable for long-running applications in which the user grants permission only once. It provides an access token that can be refreshed. Since the token exchange involves sending your secret key, perform this on a secure location, like a backend service, and not from a client such as a browser or from a mobile app.

The first step to get an access and refresh token through the Authorization Code Flow is to build an url.

AuthorizationCodeFlow authorizationCodeFlow = new AuthorizationCodeFlow.Builder()
        .setClientId("CLIENT ID")
        .setRedirectUri("https://www.example.com/callback/")
        .setResponseType("code")
        .setScopes(Arrays.asList(
                 AuthorizationScope.APP_REMOTE_CONTROL,
                 AuthorizationScope.PLAYLIST_MODIFY_PRIVATE))
         .build();

The above code will result in the following url.

https://accounts.spotify.com/authorize?client_id=CLIENT ID&response_type=code&redirect_uri=https://www.example.com/callback/&scope=app-remote-control playlist-modify-private&state=null&show_dialog=false

By visiting the url it will display a prompt to authorize access within the given scopes. Authorizing access will redirect the user to the given redirect uri. An authorization code will also be returned, it can be found as a query parameter in the redirect uri. Use this authorization code for the second step.

For the second step the following values need to be provided:

• Client ID
• Client Secret
• Authorization Code (the code that got returned when redirected from spotify)
• Redirect Uri (the redirect uri that was given in the first step)

AuthorizationRequestToken authorizationRequestToken = new AuthorizationRequestToken();
AuthorizationCodeFlowTokenResponse token = authorizationRequestToken
                .getAuthorizationCodeToken(
                        "CLIENT ID",
                        "CLIENT SECRET",
                        "AUTHORIZATION CODE",
                        "REDIRECT URI");

The authorization code flow with PKCE is the best option for mobile and desktop applications where it is unsafe to store your client secret. It provides your app with an access token that can be refreshed. For further information about this flow, see IETF RFC-7636.

The first step to get an access and refresh token through the Authorization PKCE Code Flow is to build an url.

AuthorizationCodeFlowPKCE pkce = new AuthorizationCodeFlowPKCE.Builder()
     .setClientId("CLIENT ID")
     .setRedirectUri("REDIRECT URI")
     .setResponseType("code")
     .setScopes(Arrays.asList(
              AuthorizationScope.APP_REMOTE_CONTROL,
              AuthorizationScope.PLAYLIST_MODIFY_PRIVATE))
     .setCodeChallengeMethod("S256")
     .setCodeChallenge("CODE CHALLENGE")
     .setState("STATE")
     .build();

The above code will result in the following url.

https://accounts.spotify.com/authorize?client_id=CLIENT ID&response_type=code&redirect_uri=REDIRECT URI&scope=app-remote-control playlist-modify-private&state=STATE&code_challenge_method=S256&code_challenge=CODE CHALLENGE

By visiting the url it will display a prompt to authorize access within the given scopes. Authorizing access will redirect the user to the given redirect uri. An authorization code will also be returned, it can be found as a query parameter in the redirect uri. Use this authorization code for the second step.

For the second step the following values need to be provided:

• Client ID
• Authorization Code (the code that got returned when redirected from spotify)
• Redirect Uri (the redirect uri that was given in the first step)
• Code verifier (the one that was generated at the first step)

AuthorizationPKCERequestToken auth = new AuthorizationPKCERequestToken();
final String accessToken = auth.getAuthorizationCodeToken(
        "CLIENT ID",
        "CODE",
        "REDIRECT URI",
        "CODE VERIFIER")
        .getAccessToken();

The AuthorizationCodeFlowTokenResponse contains the access and refresh token. The access and refresh token can be used to access api endpoints.

SpotifyApi spotifyApi = new SpotifyApi("ACCESS TOKEN", "REFRESH TOKEN");
AlbumFull albumFull = spotifyApi.getAlbum("ALBUM ID");

When the access token has expired it can be refreshed using AuthorizationRefreshToken

AuthorizationCodeFlowTokenResponse token = authorizationRefreshToken
                .refreshAccessToken(
                        "CLIENT ID",
                        "CLIENT SECRET",
                        "REFRESH TOKEN");

The above code example will return an AuthorizationCodeFlowTokenResponse which contains the new access and refresh token.

Many API endpoints have optional parameters. Passing in optional parameters is done with a Map. If you don't want to pass any optional parameters then just pass in an empty Map.

SpotifyApi spotifyApi = new SpotifyApi("ACCESS TOKEN");

Map<String, String> optionalParameters = new HashMap<>();
optionalParameters.put("limit", "10");

CategoryFullPaging categories = spotifyApi.getCategories(optionalParameters);

As of this moment the library can throw three different exceptions.

This exception will be thrown when the HTTP request has failed on the server side of Spotify. This can for instance happen when the Spotify server is not reachable at the moment.

This exception will be thrown when the HTTP request has been successfully handled, but the desired results has not been returned. This can for instance happen when one of the provided parameters are invalid.

This exception will be thrown when authorization has failed. This may be thrown when for instance the provided credentials are not valid.

Because this library is very simple and straightforward with a clear and simple interface. You only need to provide a few credential info and you're ready to access the endpoints. All other stuff is already taken care for you. When looking at other similar existing libraries, they have really complicated constructs to access an endpoint, where with this library it can be done with 1 line of code.
