# 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`
