# Google Contacts

Access the Google People API with managed OAuth authentication. Manage contacts, contact groups, and search your address book.

## Quick Start

```bash
# List contacts
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/google-contacts/v1/people/me/connections?personFields=names,emailAddresses,phoneNumbers&pageSize=10')
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-contacts/{native-api-path}
```

Replace `{native-api-path}` with the actual Google People API endpoint path. The gateway proxies requests to `people.googleapis.com` and automatically injects your OAuth token.

## 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 Contacts 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-contacts&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-contacts'}).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-contacts",
    "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 Contacts connections, specify which one to use with the `Maton-Connection` header:

```bash
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/google-contacts/v1/people/me/connections?personFields=names&pageSize=10')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
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.

### Other Contacts

Other contacts are people you've interacted with (e.g., via email) but haven't explicitly added to your contacts.

#### List Other Contacts

}
```

## Person Fields

Use these fields with `personFields` or `readMask` parameters:

| Field | Description |
|-------|-------------|
| `names` | Display name, given name, family name |
| `emailAddresses` | Email addresses with type |
| `phoneNumbers` | Phone numbers with type |
| `addresses` | Postal addresses |
| `organizations` | Company, title, department |
| `biographies` | Bio/notes about the person |
| `birthdays` | Birthday information |
| `urls` | Website URLs |
| `photos` | Profile photos |
| `memberships` | Contact group memberships |
| `metadata` | Source and update information |

Multiple fields: `personFields=names,emailAddresses,phoneNumbers,organizations`

## Pagination

Use `pageSize` and `pageToken` for pagination:

```bash
GET /google-contacts/v1/people/me/connections?personFields=names&pageSize=100&pageToken=NEXT_PAGE_TOKEN
```

Response includes pagination info:

```json
{
  "connections": [...],
  "totalPeople": 500,
  "nextPageToken": "...",
  "nextSyncToken": "..."
}
```

Continue fetching with `pageToken` until `nextPageToken` is not returned.

## Code Examples

### JavaScript

```javascript
const response = await fetch(
  'https://gateway.maton.ai/google-contacts/v1/people/me/connections?personFields=names,emailAddresses&pageSize=50',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();
```

### Python

```python
import os
import requests

response = requests.get(
    'https://gateway.maton.ai/google-contacts/v1/people/me/connections',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={
        'personFields': 'names,emailAddresses,phoneNumbers',
        'pageSize': 50
    }
)
data = response.json()
```

## Notes

- Resource names for contacts follow the pattern `people/c{id}` (e.g., `people/c1234567890`)
- Resource names for contact groups follow the pattern `contactGroups/{id}` (e.g., `contactGroups/abc123`)
- System contact groups include: `starred`, `friends`, `family`, `coworkers`, `myContacts`, `all`, `blocked`
- The `personFields` parameter is required for most read operations
- When updating contacts, include the `etag` to prevent overwriting concurrent changes
- Mutate requests for the same user should be sent sequentially to avoid increased latency and failures
- IMPORTANT: When using curl commands, use `curl -g` when URLs contain brackets 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

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Missing Google Contacts connection or invalid request |
| 401 | Invalid or missing Maton API key |
| 403 | Permission denied (check OAuth scopes) |
| 404 | Contact or group not found |
| 429 | Rate limited |
| 4xx/5xx | Passthrough error from Google People 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-contacts`. For example:

- Correct: `https://gateway.maton.ai/google-contacts/v1/people/me/connections`
- Incorrect: `https://gateway.maton.ai/v1/people/me/connections`
