# PostHog

Access the PostHog API with managed authentication. Query product analytics events with HogQL, manage feature flags, analyze user behavior, view session recordings, and run A/B experiments.

## Quick Start

```bash
# List projects
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/posthog/api/projects/')
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/posthog/{native-api-path}
```

Replace `{native-api-path}` with the actual PostHog API endpoint path. The gateway proxies requests to `{subdomain}.posthog.com` and automatically injects your credentials.

## 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 PostHog 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=posthog&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': 'posthog'}).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": "ce2b0840-4e39-4b58-b607-7290fa7a3595",
    "status": "ACTIVE",
    "creation_time": "2026-02-23T09:37:57.686121Z",
    "last_updated_time": "2026-02-23T09:39:11.851118Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "posthog",
    "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 PostHog 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/posthog/api/projects/')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', 'ce2b0840-4e39-4b58-b607-7290fa7a3595')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
```

If omitted, the gateway uses the default (oldest) active connection.

## Pagination

PostHog uses offset-based pagination:

```bash
GET /posthog/api/projects/{project_id}/persons/?limit=10&offset=20
```

Response includes pagination info:

```json
{
  "count": 100,
  "next": "https://us.posthog.com/api/projects/{project_id}/persons/?limit=10&offset=30",
  "previous": "https://us.posthog.com/api/projects/{project_id}/persons/?limit=10&offset=10",
  "results": [...]
}
```

For session recordings, use `has_next` boolean:

```json
{
  "results": [...],
  "has_next": true
}
```

## Code Examples

### JavaScript

```javascript
const response = await fetch(
  'https://gateway.maton.ai/posthog/api/projects/',
  {
    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/posthog/api/projects/',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()
```

### Python - HogQL Query

```python
import os
import requests

response = requests.post(
    'https://gateway.maton.ai/posthog/api/projects/@current/query/',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'query': {
            'kind': 'HogQLQuery',
            'query': 'SELECT event, count() FROM events GROUP BY event LIMIT 10'
        }
    }
)
data = response.json()
```

## Notes

- Use `@current` as a shortcut for the current project ID (e.g., `/api/projects/@current/dashboards/`)
- Project IDs are integers (e.g., `136209`)
- Person UUIDs are in standard UUID format
- The Events endpoint is deprecated; use the Query endpoint with HogQL instead
- Session recordings include activity metrics like click_count, keypress_count
- PostHog uses soft delete: use `PATCH` with `{"deleted": true}` instead of HTTP DELETE
- IMPORTANT: When piping curl output to `jq` or other commands, environment variables like `$MATON_API_KEY` may not expand correctly in some shell environments. Use Python examples instead.

## Error Handling

| Status | Meaning |
|--------|---------|
| 400 | Missing PostHog connection |
| 401 | Invalid or missing Maton API key |
| 429 | Rate limited |
| 4xx/5xx | Passthrough error from PostHog API |

### Rate Limits

- Analytics endpoints (insights, persons, recordings): 240/minute, 1200/hour
- HogQL query endpoint: 120/hour
- CRUD endpoints: 480/minute, 4800/hour
