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

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

Maton 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:

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 PostHog 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=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

python <<'EOF'
import urllib.request, os, json
data = json.dumps({'app': 'posthog'}).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": "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

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 PostHog connections, specify which one to use with the Maton-Connection header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/posthog/api/projects/')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
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.

Security & Permissions

• Access is scoped to events, persons, feature flags, insights, and dashboards within the connected PostHog account.
• All write operations require explicit user approval. Before executing any create, update, or delete call, confirm the target resource and intended effect with the user.

  "results": [...]
}

For session recordings, use has_next boolean:

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

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/posthog/api/projects/',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests

response = requests.get(
    'https://api.maton.ai/posthog/api/projects/',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()

Python - HogQL Query

import os
import requests

response = requests.post(
    'https://api.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

Rate Limits

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