Quickstart

Before you begin

Select or create a Cloud Platform project.
Enable billing for your project.
Enable the Cloud Channel API API.
Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install @google-cloud/channel

Using the client library

// Reads the secrets from a `oauth2.keys.json` file, which should be downloaded
// from the Google Developers Console and saved in the same directory with the
// sample app.

// This sample app only calls read-only methods from the Channel API. Include
// additional scopes if calling methods that modify the configuration.
const SCOPES = ['https://www.googleapis.com/auth/apps.order'];

async function listCustomers(authClient, accountNumber) {
  // Imports the Google Cloud client library
  const {CloudChannelServiceClient} = require('@google-cloud/channel');

  // Instantiates a client using OAuth2 credentials.
  const sslCreds = grpc.credentials.createSsl();
  const credentials = grpc.credentials.combineChannelCredentials(
    sslCreds,
    grpc.credentials.createFromGoogleCredential(authClient)
  );

  // Instantiates a client
  const client = new CloudChannelServiceClient({
    sslCreds: credentials,
  });

  // Calls listCustomers() method
  const customers = await client.listCustomers({
    parent: `accounts/${accountNumber}`,
  });
  console.info(customers);
}

/**
 * Create a new OAuth2Client, and go through the OAuth2 content
 * workflow.  Return the full client to the callback.
 */

Supported Node.js Versions

Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js. If you are using an end-of-life version of Node.js, we recommend that you update as soon as possible to an actively supported LTS version.

Google's client libraries support legacy versions of Node.js runtimes on a best-efforts basis with the following warnings:

Legacy versions are not tested in continuous integration.
Some security patches and features cannot be backported.
Dependencies cannot be kept up-to-date.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed through npm dist-tags. The dist-tags follow the naming convention legacy-(version). For example, npm install @google-cloud/channel@legacy-8 installs client libraries for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be stable. The code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against stable libraries are addressed with the highest priority.
