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.

EOF

Create Connection

python <<'EOF'
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

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": "2026-02-11T00:25:10.464852Z",

    "app": "beehiiv",
    "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 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.

Security & Permissions

• Access is scoped to newsletter publications, subscriptions, posts, custom fields, segments, and automations within the connected beehiiv 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.

Pagination

beehiiv supports two pagination methods:

Cursor-Based (Recommended)

GET /beehiiv/v2/publications/{publication_id}/subscriptions?limit=10&cursor={next_cursor}

Response includes:

{
  "data": [...],
  "limit": 10,
  "has_more": true,
  "next_cursor": "eyJ0aW1lc3RhbXAiOiIyMDI0LTA3LTAyVDE3OjMwOjAwLjAwMDAwMFoifQ=="
}

Use the next_cursor value for subsequent requests.

Page-Based (Deprecated)

GET /beehiiv/v2/publications?page=2&limit=10

Response includes:

{
  "data": [...],
  "page": 2,
  "limit": 10,
  "total_results": 50,
  "total_pages": 5
}

Note: Page-based pagination is limited to 100 pages maximum.

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

• Publication IDs start with pub_
• Subscription IDs start with sub_
• Timestamps are Unix timestamps (seconds since epoch)
• Custom fields must be created before use in subscriptions
• Cursor-based pagination is recommended for better performance
• Page-based pagination is deprecated and limited to 100 pages
• 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

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:

• Correct: https://api.maton.ai/beehiiv/v2/publications
• Incorrect: https://api.maton.ai/v2/publications
