Google Ads

Google Ads

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

Quick Start

# List accessible customers
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-ads/v23/customers:listAccessibleCustomers')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
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.

Authentication

All requests require the Maton API key in the Authorization header:

Authorization: Bearer $MATON_API_KEY

Environment Variable: Set your API key as MATON_API_KEY:

export MATON_API_KEY="YOUR_API_KEY"

Getting Your API Key

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

Connection Management

Manage your Google Ads OAuth connections at https://api.maton.ai.

List Connections

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

Create Connection

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'google-ads'}).encode()
req = urllib.request.Request('https://api.maton.ai/connections', 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

Get Connection

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

Response:

{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "google-ads",
    "metadata": {}
  }
}

Open the returned url in a browser to complete OAuth authorization.

Delete Connection

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

Specifying Connection

If you have multiple Google Ads connections, specify which one to use with the Maton-Connection header:

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/v23/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 include this header to ensure requests go to the intended account.

const customers = await fetch(
  'https://api.maton.ai/google-ads/v23/customers:listAccessibleCustomers',
  { headers: { 'Authorization': Bearer ${process.env.MATON_API_KEY} } }
).then(r => r.json());

const campaigns = await fetch(
  https://api.maton.ai/google-ads/v23/customers/${customerId}/googleAds:search,
  {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json',
      'Authorization': Bearer ${process.env.MATON_API_KEY}

).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/v23/customers/{customer_id}/googleAds:search',

Notes

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

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:

Resources

# List accessible customers
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/google-ads/v23/customers:listAccessibleCustomers')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
