Step by Step Guide to Building a Google Ads API Integration in Ruby

Introduction

Hey there, fellow developer! Ready to dive into the world of Google Ads API integration? You're in for a treat. The Google Ads API is a powerhouse tool that'll let you programmatically manage your Google Ads accounts with ease. Whether you're building a custom dashboard or automating campaign management, this guide will get you up and running in no time.

Prerequisites

Before we jump in, make sure you've got:

• A Ruby environment set up (I know you've probably got this covered)
• A Google Ads account and the necessary credentials

If you're all set, let's roll!

Installation

First things first, let's get that gem installed:

gem install google-ads-googleads

Easy peasy, right?

Authentication

Now, let's tackle authentication. You'll need OAuth 2.0 credentials:

1. Head over to the Google Cloud Console
2. Create a project (if you haven't already)
3. Enable the Google Ads API
4. Create OAuth 2.0 credentials

Once you've got your credentials, let's configure the client library:

require 'google/ads/google_ads'

Google::Ads::GoogleAds::Config.new do |config|
  config.client_id = 'YOUR_CLIENT_ID'
  config.client_secret = 'YOUR_CLIENT_SECRET'
  config.refresh_token = 'YOUR_REFRESH_TOKEN'
  config.developer_token = 'YOUR_DEVELOPER_TOKEN'
  config.login_customer_id = 'YOUR_LOGIN_CUSTOMER_ID'
end

Basic API Request

Time to make your first API call! Here's how to create a client and fetch some account info:

client = Google::Ads::GoogleAds::GoogleAdsClient.new

response = client.service.google_ads.search(
  customer_id: 'YOUR_CUSTOMER_ID',
  query: 'SELECT customer.id, customer.descriptive_name FROM customer LIMIT 1'
)

puts response.results.first.customer.descriptive_name

Boom! You've just made your first API call. How cool is that?

Common Operations

Now that you've got the basics down, let's look at some common operations:

Managing Campaigns

campaign_budget_service = client.service.campaign_budget
campaign_service = client.service.campaign

# Create a campaign budget
budget_operation = client.operation.create_resource.campaign_budget do |b|
  b.name = "My Budget"
  b.amount_micros = 500_000_000
end

budget_response = campaign_budget_service.mutate_campaign_budgets(
  customer_id: 'YOUR_CUSTOMER_ID',
  operations: [budget_operation]
)

# Create a campaign
campaign_operation = client.operation.create_resource.campaign do |c|
  c.name = "My Awesome Campaign"
  c.campaign_budget = budget_response.results.first.resource_name
  c.advertising_channel_type = :SEARCH
  c.status = :PAUSED
end

campaign_service.mutate_campaigns(
  customer_id: 'YOUR_CUSTOMER_ID',
  operations: [campaign_operation]
)

Handling Responses

When working with the API, you'll want to handle responses gracefully:

begin
  response = client.service.google_ads.search(
    customer_id: 'YOUR_CUSTOMER_ID',
    query: 'SELECT campaign.id, campaign.name FROM campaign'
  )
  response.results.each do |row|
    puts "Campaign ID: #{row.campaign.id}, Name: #{row.campaign.name}"
  end
rescue Google::Ads::GoogleAds::Errors::GoogleAdsError => e
  e.failure.errors.each do |error|
    puts "Error with message: #{error.message}"
    puts "Error code : #{error.error_code}"
  end
end

Best Practices

Remember to:

• Respect rate limits (the library handles this for you, but be mindful)
• Log requests and responses for debugging
• Use partial failure for batch operations to avoid all-or-nothing scenarios

Advanced Topics

Once you're comfortable with the basics, you can explore:

• Batch processing for efficiency
• Creating custom reports
• Using extensions and other advanced features

Conclusion

And there you have it! You're now equipped to build powerful integrations with the Google Ads API using Ruby. Remember, practice makes perfect, so don't be afraid to experiment and push the boundaries of what you can do.
