Creating MindsphereCredentials using a User Token

MindsphereCredentials credentials = MindsphereCredentials.userTokenBuilder()
                                        .authorization(<user_token>)
                                        .build();
Deprecated Method

The following method for creating service credentials using a user token is deprecated and shall not be used anymore:

MindsphereCredentials credentials = MindsphereCredentials.builder()
                                        .authorization(<user_token>)
                                        .build();

Creating MindsphereCredentials using App Specific Service Credentials

The app specific service credentials are obtained from Developer Cockpit or Operator Cockpit. During the development of an application you may provide the service credentials programmatically. The final application should obtain the client ID, client secret, app name and app version from the environment variables and the host tenant and user tenant from the user token as shown below.

                                        .keyStoreClientSecret(<client_secret>)
                                        .appName(<app_name>)
                                        .appVersion(<app_version>)
                                        .hostTenant(<host_tenant>)
                                        .userTenant(<user_tenant>)
                                        .build();

MindsphereCredentials credentials = MindsphereCredentials.appCredentialsBuilder()

                                        .build();

Note

The host tenant and user tenant values should not be hard-coded in the application as they are subject to change. MindSphereCredentials objects can extract these values from the user token provided as authorization parameter.

Creating MindsphereCredentials using Tenant Specific Service Credentials

The tenant specific service credentials must be provided programmatically or via environment variables. Tenant specific service credentials are obtained as described in Accessing MindSphere APIs with Service Credentials. If credentials are set via environment variables, the MindsphereCredentials object does not need to be build.

                                        .tenant(<tenant>)
                                        .build();

                                        .clientSecret(<client_secret>)
                                        .tenant(<tenant_name>)
                                        .build();

                                        .tokenType(TokenScope.SUB_TENANT)
                                        .build();
