Google Ads API Nodejs Client Library

Usage

Authentication

import { UserRefreshClient, JWT } from 'google-auth-library';

// for web application
const authClient = new UserRefreshClient({
  clientId: '<CLIENT_ID>',
  clientSecret: '<CLIENT_SECRET>',
  refreshToken: '<REFRESH_TOKEN>',
});

// or use JWT for service account
const authClient = new JWT({
  keyFile: '<KEY_FILE>',
  subject: '<GOOGLE_ADS_EMAIL>',
  scopes: ['https://www.googleapis.com/auth/adwords'],
});

Customer

import { Customer } from '@htdangkhoa/google-ads';

const service = new Customer({
  auth: authClient,
  developer_token: '<DEVELOPER_TOKEN>',
});

const { resource_names: customers } = await service.listAccessibleCustomers();

// ...

Search

import { GoogleAds } from '@htdangkhoa/google-ads';

const service = new GoogleAds(
  {
    auth: authClient,
    developer_token: '<DEVELOPER_TOKEN>',
  },
  {
    customer_id: '<CUSTOMER_ID>',
  },
);

const customerClients = await service.search({
  query: `
    SELECT
      customer_client.descriptive_name,
      customer_client.resource_name,
      customer_client.client_customer,
      customer_client.level,
      customer_client.manager
    FROM customer_client
  `,
});

// ...

Search stream

import { GoogleAds } from '@htdangkhoa/google-ads';

const service = new GoogleAds(
  {
    auth: authClient,
    developer_token: '<DEVELOPER_TOKEN>',
  }, {
    customer_id: '<MANAGER_ID>',
  }
);

const response = service
  .setCustomerId('<CUSTOMER_ID>') // you can switch customer id
  .setLoginCustomerId('<MANAGER_ID>')
  .searchStream({
    query: `
      SELECT
        campaign.id,
        campaign.name,
        campaign.status
      FROM campaign
    `,
  });

for await (const { results } of response) {
  // ...
}

Campaign

import { GoogleAds } from '@htdangkhoa/google-ads';

const service = new GoogleAds(
  {
    auth: authClient,
    developer_token: '<DEVELOPER_TOKEN>',
  },
  {
    customer_id: '<CUSTOMER_CLIENT_ID>',
    login_customer_id: '<CUSTOMER_ID>',
  },
);

const campaigns = await service.search({
  query: `
    SELECT
      campaign.id,
      campaign.name,
      campaign.status
    FROM campaign
  `,
});

// ...

Mutate

import { GoogleAds } from '@htdangkhoa/google-ads';

const service = new GoogleAds(
  {
    auth: authClient,
    developer_token: '<DEVELOPER_TOKEN>',
  },
  {
    customer_id: '<CUSTOMER_CLIENT_ID>',
    login_customer_id: '<CUSTOMER_ID>',
  },
);

const response = await service.mutate({
  mutate_operations: [
    {
      campaign_operation: {
        create: {
          // ...
        },
        update: {
          // ...
        },
        remove: '<CAMPAIGN_RESOURCE_NAME>',
      },
    },
  ],
  partial_failure: true,
});

// ...

Query Builder

import { QueryBuilder } from '@htdangkhoa/google-ads';

const query = new QueryBuilder()
  .select(
    'campaign.id',
    'campaign.name',
    'segments.device',
    'metrics.clicks',
  )
  .from('campaign')
  .where(
    {
      attribute: 'metrics.impressions',
      operator: Operators.GREATER_THAN,
      value: "0",
    },
    {
      attribute: 'segments.device',
      operator: Operators.EQUALS,
      value: "MOBILE",
    },
    {
      attribute: 'segments.date',
      operator: Operators.DURING,
      value: Functions.LAST_30_DAYS,
    },
  )
  .orderBy(
    {
      attribute: 'metrics.clicks',
      direction: Order.DESC,
    },
  )
  .limit(10)
  .build();

const response = await service.search({ query });

Logging

Requests are logged with a one line summary and the full request/response body and headers.

Log type	Log name	Success level	Failure level
SUMMARY	Google::Ads::GoogleAds::Summary	INFO	WARN
DETAIL	Google::Ads::GoogleAds::Detail	DEBUG	INFO

Basic

import { GoogleAds } from '@htdangkhoa/google-ads';

const service = new GoogleAds(
  {
    auth: authClient,
    developer_token: '<DEVELOPER_TOKEN>',
    logging: true,
  },
  {
    customer_id: '<CUSTOMER_ID>',
  },
);

Specific Log Type (SUMMARY or DETAIL)

import { GoogleAds } from '@htdangkhoa/google-ads';

const service = new GoogleAds(
  {
    auth: authClient,
    developer_token: '<DEVELOPER_TOKEN>',
    logging: {
      summary: true,
      detail: false,
    },
  },
  {
    customer_id: '<CUSTOMER_ID>',
  },
);

gRPC Client Options

The ServiceOptions is extended from @grpc/grpc-js ClientOptions, so you can pass any options you want to the client.

import { GoogleAds } from '@htdangkhoa/google-ads';

const service = new GoogleAds(
  {
    auth: authClient,
    developer_token: '<DEVELOPER_TOKEN>',
    logging: {
      summary: true,
      detail: false,
    },
    interceptors: [
      // your interceptors
    ],
  },
  {
    customer_id: '<CUSTOMER_ID>',
  },
);

Interceptors

Development

Prerequisites

• Protocol Buffer Compiler (protoc) version 3.0.0 or greater. The latest version can be downloaded from here
• Node.js version 16 or greater (LTS recommended) and npm version 8 or greater. The latest version of Node.js can be downloaded from here

Building

1. Install dependencies

   yarn install

2. Pull in the new protos and compile them

   yarn generate <GOOGLE_ADS_API_VERSION>
   
   # example
   yarn generate v18

3. Make sure the version number in the src folder is correct (it should match the version number you passed to the generate command)

4. Run tests to make sure everything worked (you may need to update the version numbers here)

   yarn test

5. Build the library

   yarn build

6. Make a pull request, get it approved and merged into main
