Introduction
# Google Ads
Access the Google Ads API with managed OAuth authentication. Query campaigns, ad groups, keywords, and performance metrics using GAQL.
## Quick Start
```bash # List accessible customers python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://gateway.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://gateway.maton.ai/google-ads/{native-api-path} ```
Replace `{native-api-path}` with the actual Google Ads API endpoint path. The gateway 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`:
```bash export MATON_API_KEY="YOUR_API_KEY" ```
### Getting Your API Key
1. Sign in or create an account at [maton.ai](https://maton.ai) 2. Go to [maton.ai/settings](https://maton.ai/settings) 3. Copy your API key
## Connection Management
Manage your Google Ads OAuth connections at `https://ctrl.maton.ai`.
### List Connections
```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.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
```bash python <<'EOF' import urllib.request, os, json data = json.dumps({'app': 'google-ads'}).encode() req = urllib.request.Request('https://ctrl.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
```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.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:** ```json { "connection": { "connection_id": "21fd90f9-5935-43cd-b6c8-bde9d915ca80", "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
```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.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:
```bash python <<'EOF' import urllib.request, os, json data = json.dumps({'query': 'SELECT campaign.id, campaign.name FROM campaign'}).encode() req = urllib.request.Request('https://gateway.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', '21fd90f9-5935-43cd-b6c8-bde9d915ca80') print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2)) EOF ```
If omitted, the gateway uses the default (oldest) active connection.
## API Reference
### List Accessible Customers
```bash GET /google-ads/v23/customers:listAccessibleCustomers ```
### Search (GAQL Query)
```bash POST /google-ads/v23/customers/{customerId}/googleAds:search Content-Type: application/json
{ "query": "SELECT campaign.id, campaign.name, campaign.status FROM campaign ORDER BY campaign.id" } ```
### Search Stream (for large results)
```bash POST /google-ads/v23/customers/{customerId}/googleAds:searchStream Content-Type: application/json
{ "query": "SELECT campaign.id, campaign.name FROM campaign" } ```
## Common GAQL Queries
### List Campaigns
```sql SELECT campaign.id, campaign.name, campaign.status, campaign.advertising_channel_type FROM campaign WHERE campaign.status != 'REMOVED' ORDER BY campaign.name ```
### Campaign Performance
```sql 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
```sql SELECT ad_group.id, ad_group.name, ad_group.status, campaign.id, campaign.name FROM ad_group WHERE ad_group.status != 'REMOVED' ```
### List Keywords
```sql SELECT ad_group_criterion.keyword.text, ad_group_criterion.keyword.match_type, metrics.impressions, metrics.clicks FROM keyword_view WHERE segments.date DURING LAST_30_DAYS ```
## Code Examples
### JavaScript
```javascript // Get customer IDs const customers = await fetch( 'https://gateway.maton.ai/google-ads/v23/customers:listAccessibleCustomers', { headers: { 'Authorization': `Bearer ${process.env.MATON_API_KEY}` } } ).then(r => r.json());
// Query campaigns const campaigns = await fetch( `https://gateway.maton.ai/google-ads/v23/customers/${customerId}/googleAds:search`, { method: 'POST', headers: { 'Content-Type': 'application/json', 'Authorization': `Bearer ${process.env.MATON_API_KEY}` }, body: JSON.stringify({ query: 'SELECT campaign.id, campaign.name FROM campaign' }) } ).then(r => r.json()); ```
### Python
```python import os import requests
headers = {'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
# Query campaigns response = requests.post( f'https://gateway.maton.ai/google-ads/v23/customers/{customer_id}/googleAds:search', headers=headers, json={'query': 'SELECT campaign.id, campaign.name FROM campaign'} ) ```
## Notes
- Use `listAccessibleCustomers` first to get customer IDs - Customer IDs are 10-digit numbers (remove dashes) - Monetary values are in micros (divide by 1,000,000) - Date ranges: `LAST_7_DAYS`, `LAST_30_DAYS`, `THIS_MONTH` - Status values: `ENABLED`, `PAUSED`, `REMOVED` - IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets (`fields[]`, `sort[]`, `records[]`) to disable glob parsing - IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$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
1. Check that the `MATON_API_KEY` environment variable is set:
```bash echo $MATON_API_KEY ```
2. Verify the API key is valid by listing connections:
```bash python <<'EOF' import urllib.request, os, json req = urllib.request.Request('https://ctrl.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://gateway.maton.ai/google-ads/v23/customers:listAccessibleCustomers` - Incorrect: `https://gateway.maton.ai/v23/customers:listAccessibleCustomers`
