Google Ads

Access the Google Ads API with managed OAuth authentication. Query campaigns, ad groups, keywords, and performance metrics using GAQL.

Quick Start

CLI:

maton google-ads query -c 1234567890 --resource campaign --fields 'campaign.id, campaign.status'

maton google-ads query -c 1234567890 --gaql 'SELECT campaign.id, campaign.status FROM campaign'

maton api '/google-ads/v24/customers/1234567890/googleAds:search' -f query='SELECT campaign.id, campaign.status FROM campaign'

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'SELECT campaign.id, campaign.name, campaign.status FROM campaign'}).encode()
req = urllib.request.Request('https://api.maton.ai/google-ads/v24/customers/1234567890/googleAds:search', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://api.maton.ai/google-ads/{native-api-path}

Maton proxies requests to googleads.googleapis.com and automatically injects OAuth and developer tokens.

Installation

NPM:

npm install -g @maton-ai/cli

Homebrew:

brew install maton-ai/cli/maton

Authentication

CLI:

maton login                          # Opens browser for API key
maton login --interactive            # Skip browser, paste API key directly
maton whoami                         # Show current auth state

Manual:

1. Sign in or create an account at maton.ai
2. Go to maton.ai/settings
3. Copy your API key
4. Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Specifying Connection

If you have multiple Google Ads connections, specify which one to use:

CLI:

maton google-ads campaign list -c 1234567890 --connection {connection_id}

maton api /google-ads/v24/customers/1234567890/googleAds:search --connection {connection_id}

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'SELECT campaign.id, campaign.name FROM campaign'}).encode()
req = urllib.request.Request('https://api.maton.ai/google-ads/v24/customers/1234567890/googleAds:search', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('Maton-Connection', '{connection_id}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

If you have multiple connections, always specify the connection to ensure requests go to the intended account.

Security & Permissions

• Access is scoped to campaigns, ad groups, ads, keywords, and reporting within the connected Google Ads account.
• All write operations require explicit user approval. Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

API Reference

List Accessible Customers

GET /google-ads/v24/customers:listAccessibleCustomers

Example:

maton google-ads account list

Search (GAQL Query)

POST /google-ads/v24/customers/{customerId}/googleAds:search
Content-Type: application/json

{
  "query": "SELECT campaign.id, campaign.name, campaign.status FROM campaign ORDER BY campaign.id"
}

Example:

maton google-ads query -c 1234567890 --resource campaign --fields 'campaign.id, campaign.name, campaign.status' --order-by 'campaign.id'

List Keywords

POST /google-ads/v24/customers/{customerId}/googleAds:search
Content-Type: application/json

{
  "query": "SELECT ad_group_criterion.keyword.text, ad_group_criterion.keyword.match_type, ad_group_criterion.status, metrics.impressions, metrics.clicks, metrics.cost_micros FROM keyword_view WHERE segments.date DURING LAST_30_DAYS ORDER BY metrics.impressions DESC"
}

Example:

maton google-ads keyword list -c 1234567890 --date-range LAST_7_DAYS -L 25 --campaign-id 99999

Note: This command requests metrics, so it cannot be run against a manager (MCC) account directly. Run it against the client customer ID under the manager, optionally with --login-customer-id. See Manager (MCC) Account Access.

Search Stream (for large results)

POST /google-ads/v24/customers/{customerId}/googleAds:searchStream
Content-Type: application/json

{
  "query": "SELECT campaign.id, campaign.name FROM campaign"
}

Example:

maton google-ads query-stream -c 1234567890 --resource campaign --fields 'campaign.id, campaign.name'

Common GAQL Queries

List Campaigns

SELECT campaign.id, campaign.name, campaign.status, campaign.advertising_channel_type
FROM campaign
WHERE campaign.status != 'REMOVED'
ORDER BY campaign.name

Campaign Performance

SELECT campaign.id, campaign.name, metrics.impressions, metrics.clicks, metrics.cost_micros, metrics.conversions
FROM campaign
WHERE segments.date DURING LAST_30_DAYS
ORDER BY metrics.impressions DESC

List Ad Groups

SELECT ad_group.id, ad_group.name, ad_group.status, campaign.id, campaign.name
FROM ad_group
WHERE ad_group.status != 'REMOVED'

List Keywords with Performance

SELECT ad_group_criterion.keyword.text, ad_group_criterion.keyword.match_type, metrics.impressions, metrics.clicks, metrics.cost_micros
FROM keyword_view
WHERE segments.date DURING LAST_30_DAYS
  AND ad_group_criterion.status = 'ENABLED'
ORDER BY metrics.cost_micros DESC
LIMIT 50

Search Term Report

SELECT search_term_view.search_term, campaign.name, ad_group.name, metrics.impressions, metrics.clicks, metrics.conversions
FROM search_term_view
WHERE segments.date DURING LAST_30_DAYS
ORDER BY metrics.clicks DESC

Account-level Performance

SELECT customer.descriptive_name, segments.date, metrics.impressions, metrics.clicks, metrics.cost_micros, metrics.conversions
FROM customer
WHERE segments.date DURING LAST_7_DAYS

Manager (MCC) Account Access

When accessing a customer account through a Google Ads manager (MCC) account, pass the manager's customer ID via --login-customer-id (CLI) or the login-customer-id header (direct API). The customer ID in the path is still the client account being queried.

CLI:

# List campaigns in client account 1234567890 via manager 9876543210
maton google-ads campaign list -c 1234567890 --login-customer-id 9876543210

maton api '/google-ads/v24/customers/1234567890/googleAds:search' -H 'login-customer-id: 9876543210' -f query='SELECT campaign.id, campaign.name FROM campaign'

Python:

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'query': 'SELECT campaign.id, campaign.name FROM campaign'}).encode()
req = urllib.request.Request('https://api.maton.ai/google-ads/v24/customers/1234567890/googleAds:search', data=data, method='POST')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Content-Type', 'application/json')
req.add_header('login-customer-id', '9876543210')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Pagination

Google Ads uses token-based pagination. The CLI automatically paginates with '--paginate'.

Example:

maton google-ads campaign list -c 1234567890 --paginate

Code Examples

CLI

# List accessible customer accounts
maton google-ads account list

# Filter with jq
maton google-ads campaign list -c 1234567890 --json --jq '.results[] | {id: .campaign.id, name: .campaign.name}'

# Extract specific fields
maton google-ads campaign list -c 1234567890 --json --jq '.results[].campaign.name'

JavaScript

// Get customer IDs
const customers = await fetch(
  'https://api.maton.ai/google-ads/v24/customers:listAccessibleCustomers',
  { headers: { 'Authorization': `Bearer ${process.env.MATON_API_KEY}` } }
).then(r => r.json());

// Query campaigns
const campaigns = await fetch(
  `https://api.maton.ai/google-ads/v24/customers/${customerId}/googleAds:search`,
  {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    },
    body: JSON.stringify({
      query: 'SELECT campaign.id, campaign.name FROM campaign'
    })
  }
).then(r => r.json());

Python

import os
import requests

headers = {'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}

# Query campaigns
response = requests.post(
    f'https://api.maton.ai/google-ads/v24/customers/{customer_id}/googleAds:search',
    headers=headers,
    json={'query': 'SELECT campaign.id, campaign.name FROM campaign'}
)

Notes

• Use listAccessibleCustomers first to get customer IDs
• Customer IDs are 10-digit numbers (remove dashes)
• Monetary values are in micros (divide by 1,000,000)
• Date ranges: LAST_7_DAYS, LAST_30_DAYS, THIS_MONTH
• Status values: ENABLED, PAUSED, REMOVED
• For accounts accessed through a Google Ads manager (MCC), pass the manager's customer ID with --login-customer-id (or the login-customer-id header). See Manager (MCC) Account Access.
• IMPORTANT: When using curl commands, use curl -g when URLs contain brackets (fields[], sort[], records[]) to disable glob parsing
• IMPORTANT: When piping curl output to jq or other commands, environment variables like $MATON_API_KEY may not expand correctly in some shell environments. You may get "Invalid API key" errors when piping.

Error Handling

| Status | Meaning | |--------|---------| | 400 | Missing Google Ads connection | | 401 | Invalid or missing Maton API key | | 429 | Rate limited (10 req/sec per account) | | 4xx/5xx | Passthrough error from Google Ads API |

Troubleshooting: API Key Issues

CLI:

1. Check your auth state:

maton whoami

2. Verify the API key is valid by listing connections:

maton connection list

Manual:

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

2. Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/connections')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Troubleshooting: Invalid App Name

1. Ensure your URL path starts with google-ads. For example:

• Correct: https://api.maton.ai/google-ads/v24/customers:listAccessibleCustomers
• Incorrect: https://api.maton.ai/v24/customers:listAccessibleCustomers
