Google Ads Node

Unofficial Google Ads API gRPC client library for Node

Built by Opteo

Note: This library is a minimal, low-level implementation for calling the Google Ads API with gRPC Protocol Buffers. For a more feature-complete and easier-to-use library, try our Javascript client library.

• Fully matches the lastest Google Ads API documentation
• Faster than using JSON (uses gRPC and Protocol Buffers)
• Includes Typescript definitions

$ yarn add google-ads-node

import {
  GoogleAdsClient,
  SearchGoogleAdsRequest,
  SearchGoogleAdsResponse,
  Campaign,
  Metrics
} from "google-ads-node"

// 1. Create a new client with valid authentication
const client = new GoogleAdsClient({
  access_token: "<ACCESS_TOKEN>",
  developer_token: "<DEVELOPER_TOKEN>",
  login_customer_id: "<LOGIN_CUSTOMER_ID>",
});
const customerId = "1234567890";

async function example() {
  // 2. Load a Google Ads service
  const service = client.getService("GoogleAdsService");

  // 3. Create a request
  const request = new SearchGoogleAdsRequest();
  request.setQuery(`
    SELECT
      campaign.id,
      campaign.name,
      campaign.status,
      segments.device,
      metrics.impressions,
      metrics.clicks,
      metrics.ctr,
      metrics.average_cpc,
      metrics.cost_micros
    FROM campaign
  `);
  request.setCustomerId(customerId);
  request.setPageSize(12);

  // 4. Get the results
  const result: SearchGoogleAdsResponse = await service.search(request)
    .catch((err: Error) => {
      console.log("--- Error in search ---");
      console.log(err);
    });

  // 5. Inspect the data!
  for (const row of res.getResultsList()) {
    const campaign: Campaign = row.getCampaign() as Campaign;
    const metrics: Metrics = row.getMetrics() as Metrics;

    if ((metrics.getClicks() as any) > 0) {
      console.log(`Campaign "${campaign.getName()}" has ${metrics.getClicks()} clicks.`);
    } else {
      console.log(`Campaign "${campaign.getName()}" has no clicks.`);
    }
  }
}

A valid Google Ads access_token must be provided. This usage depends on the access_token being refreshed and generated outside of the client. If the token isn't valid, an UNAUTHENTICATED error will be thrown. It's recommended to follow the instructions here for generating tokens.

const client = new GoogleAdsClient({
  developer_token: "<DEVELOPER_TOKEN>",
  access_token: "<ACCESS_TOKEN>",
});

This approach, which is recommended, internally handles access token generation and refreshing. A valid client_id, client_secret and refresh_token must be provided.

const client = new GoogleAdsClient({
  client_id: "<CLIENT_ID>",
  client_secret: "<CLIENT_SECRET>",
  refresh_token: "<REFRESH_TOKEN>",
  developer_token: "<DEVELOPER_TOKEN>",
});

To load a Google Ads service, simply use the getService method. It supports a single string, being the name of the service. For a full list of avaiable services, check out the Google Ads service reference.

const service = client.getService("AdGroupAdService");

From here, you can then use all the available methods for the service e.g. getAdGroupAd() and mutateAdGroupAds(). The parameters and return value match the format specified in the Google Ads documentation.

import { GetAdGroupRequest } from "google-ads-node";

const request = new GetAdGroupAdRequest();
const ad = await service.getAdGroupAd(request);

Note: Service methods use camelCase in this library, whereas the Google Ads documentation uses TitleCase, so if a service method was called GetCampaign(), in this library it would be getCampaign()

By default, since this library is implemented with gRPC, any calls via a service return an object in the protocol buffer format. This is a binary format object, which is difficult to understand, especially if you're not using the Typescript definitions.

Because of this, retrieving the results you want can be quite verbose. An example of this is below, where we show two methods for acquiring the id of a campaign.

const results = await service.search(request);

// Method 1
const { resultsList } = results.toObject();
const id = resultsList[0].campaign.id.value;

// Method 2
const row = results.getResultsList();
const campaign = row.getCampaign();
const id = campaign.getId().value;

If you don't wish to work directly with protocol buffers, are unfamiliar with gRPC, or just want an easier way to retrieve the data, we recommend using the parseResults client option. Setting this option to true will internally handle parsing the results in a more javascript friendly way, and return the desired entities/metrics/segments as objects (with all types correctly handled, e.g. name as a string, id as a number, etc.).

const client = new GoogleAdsClient({
  client_id: "<CLIENT_ID>",
  client_secret: "<CLIENT_SECRET>",
  refresh_token: "<REFRESH_TOKEN>",
  developer_token: "<DEVELOPER_TOKEN>",
  parseResults: true,
});

// ...

const { resultsList } = await service.search(request);
console.log(resultsList[0].campaign.id); // 123

• Release Notes
• Google Ads API Release Notes

To update the Google Ads API version, the latest proto files (in the googleapis submodule) must be compiled.

• Protoc compiler installed on your machine and added to your $PATH
• Latest dependencies installed – make sure to use yarn install since some dependencies require a C++ compilation step

1. Navigate into the googleapis/ submodule and update with git pull.

2. Run make protos to compile the *.proto files

3. The new compiled proto files should now be in src/protos/, under the google/ads/googleads/v0/ path.
