// Require the class UserCredentials available in mindsphere-sdk-node-core module
const UserCredentials = require('mindsphere-sdk-node-core').UserCredentials;

// Construct the UserCredentials object
let user_credentials = new UserCredentials({'authorization': '<user_token>'});

Creating MindsphereCredentials using App Specific Service Credentials

// Require the class AppCredentials available in `mindsphere-sdk-node-core` module
const AppCredentials = require('mindsphere-sdk-node-core').AppCredentials;

// Construct the AppCredentials object
let app_credentials = new AppCredentials({
         keyStoreClientId: '<client_id>',
         keyStoreClientSecret: '<client_secret>',
         appName: '<app-name>',
         appVersion: '<app_version>',
         hostTenant: '<host_tenant>',
         userTenant: '<user_tenant>'
});

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 TenantCredentials object does not need to be build.

let tenant_credentials = new TenantCredentials({
         clientId: '<client_id>',
         clientSecret: '<client_secret>',
         tenant:'<tenant_id>'
});

Creating MindsphereCredentials using Tenant specific Service Credentials for Subtenant Impersonation

The tenant specific service credentials for subtenant impersonation must be provided programmatically or via environment variables. If credentials are set via environment variables, the TenantCredentials object does not need to be build.
