name: mailerlite description: | MailerLite API integration with managed OAuth. Manage email subscribers, groups, campaigns, automations, and forms. Use this skill when users want to add subscribers, create email campaigns, manage groups, or work with MailerLite automations. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). compatibility: Requires network access and valid Maton API key metadata: author: maton version: "1.0" clawdbot: emoji: 🧠 requires: env: - MATON_API_KEY

MailerLite

Access the MailerLite API with managed OAuth authentication. Manage subscribers, groups, campaigns, automations, forms, fields, segments, and webhooks.

Quick Start

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

Maton proxies requests to connect.mailerlite.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 MailerLite 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=mailerlite&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': 'mailerlite'}).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": "2025-12-08T07:20:53.488460Z",
    "last_updated_time": "2026-01-31T20:03:32.593153Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "mailerlite",
    "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 MailerLite 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/mailerlite/api/subscribers')
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.

  • Access is scoped to email subscribers, groups, campaigns, automations, and forms within the connected MailerLite account.

    Pagination

    MailerLite uses cursor-based pagination for most endpoints and page-based pagination for some.

    Cursor-based Pagination

    GET /mailerlite/api/subscribers?limit=25&cursor=eyJpZCI6MTIzNDU2fQ

    Response includes pagination links: 

    {
  "data": [...],
  "links": {
    "first": "https://connect.mailerlite.com/api/subscribers?cursor=...",
    "last": null,
    "prev": null,
    "next": "https://connect.mailerlite.com/api/subscribers?cursor=eyJpZCI6MTIzNDU2fQ"
  },
  "meta": {
    "path": "https://connect.mailerlite.com/api/subscribers",
    "per_page": 25,
    "next_cursor": "eyJpZCI6MTIzNDU2fQ",
    "prev_cursor": null
  }
}

    Page-based Pagination

    GET /mailerlite/api/groups?limit=25&page=2

    Response includes page metadata: 

    {
  "data": [...],
  "meta": {
    "current_page": 2,
    "from": 26,
    "last_page": 4,
    "per_page": 25,
    "to": 50,
    "total": 100
  }
}

    Code Examples

    JavaScript

    const response = await fetch(
  'https://api.maton.ai/mailerlite/api/subscribers?limit=10',
  {
    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/mailerlite/api/subscribers',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'limit': 10}
)
data = response.json()

    Create Subscriber Example

    import os
import requests
    response = requests.post(
    'https://api.maton.ai/mailerlite/api/subscribers',
    headers={
        'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
        'Content-Type': 'application/json'
    },
    json={
        'email': 'newuser@example.com',
        'fields': {'name': 'John Doe'},
        'status': 'active'
    }
)
data = response.json()

    Notes

  • Rate limit: 120 requests per minute
  • Subscriber emails are used as unique identifiers (POST creates or updates)
  • Group names have a maximum length of 255 characters
  • Only draft campaigns can be updated
  • API versioning can be overridden via X-Version: YYYY-MM-DD header
  • 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 MailerLite connection | | 401 | Invalid or missing Maton API key | | 403 | Forbidden - insufficient permissions | | 404 | Resource not found | | 422 | Validation error | | 429 | Rate limited (120 req/min) | | 4xx/5xx | Passthrough error from MailerLite API |

    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 mailerlite. For example:

  • Correct: https://api.maton.ai/mailerlite/api/subscribers
  • Incorrect: https://api.maton.ai/api/subscribers

    • Resources

  • MailerLite API Documentation
  • MailerLite Subscribers API
  • MailerLite Groups API
  • MailerLite Campaigns API
  • Maton Community
  • Maton Support

    • πŸ’‘ Examples

    # List subscribers
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/mailerlite/api/subscribers?limit=10')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
