beehiiv

Access the beehiiv API with managed OAuth authentication. Manage newsletter publications, subscriptions, posts, custom fields, segments, tiers, and automations.

Quick Start

# List publications
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/beehiiv/v2/publications')
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/beehiiv/{native-api-path}

Maton proxies requests to api.beehiiv.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:

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 beehiiv OAuth connections at https://api.maton.ai.

import urllib.request, os, json
data = json.dumps({'app': 'beehiiv'}).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

Response:

{
  "connection": {
    "connection_id": "{connection_id}",
    "status": "ACTIVE",
    "creation_time": "2026-02-11T00:25:10.464852Z",

    "metadata": {}
  }
}

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 beehiiv 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/beehiiv/v2/publications')
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.

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/beehiiv/v2/publications',
  {
    headers: {
      'Authorization': Bearer ${process.env.MATON_API_KEY}
    }
  }
);
const data = await response.json();
console.log(data.data);

Python

import os
import requests
response = requests.get(
    'https://api.maton.ai/beehiiv/v2/publications',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()
for pub in data['data']:
    print(f"{pub['id']}: {pub['name']}")

Notes

Error Handling

| Status | Meaning | |--------|---------| | 400 | Bad request or invalid parameters | | 401 | Invalid or missing Maton API key | | 403 | Forbidden - insufficient permissions or plan limitation | | 404 | Resource not found | | 429 | Rate limited | | 500 | Internal server error |

Troubleshooting: API Key Issues

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

2. Verify the API key is valid by listing connections:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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 beehiiv. For example:

Resources

# List publications
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/beehiiv/v2/publications')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF
