Kit (formerly ConvertKit) API integration with managed OAuth. Manage email subscribers, forms, tags, sequences, broadcasts, and custom fields.

Use this skill when users want to manage their email marketing lists, create or update subscribers, manage tags, or work with email sequences and broadcasts.

For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway).

# Kit

Access the Kit (formerly ConvertKit) API with managed OAuth authentication. Manage subscribers, tags, forms, sequences, broadcasts, custom fields, and webhooks.

Quick Start

# List subscribers
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/kit/v4/subscribers?per_page=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://gateway.maton.ai/kit/{native-api-path}

Replace `{native-api-path}` with the actual Kit API endpoint path. The gateway proxies requests to `api.kit.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](https://maton.ai)

2. Go to [maton.ai/settings](https://maton.ai/settings)

3. Copy your API key

Connection Management

Manage your Kit OAuth connections at `https://ctrl.maton.ai`.

List Connections

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://ctrl.maton.ai/connections?app=kit&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': 'kit'}).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

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:**

{
  "connection": {
    "connection_id": "cb2025b3-706f-4b5d-87a5-c6809c0c7ec4",
    "status": "ACTIVE",
    "creation_time": "2026-02-07T00:04:08.476727Z",
    "last_updated_time": "2026-02-07T00:05:58.001964Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "kit",
    "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://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 Kit connections, specify which one to use with the `Maton-Connection` header:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/kit/v4/subscribers')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', 'cb2025b3-706f-4b5d-87a5-c6809c0c7ec4')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

GET /kit/v4/subscribers?per_page=100&after=WzE0OV0=

Response includes pagination info:

{
  "subscribers": [...],
  "pagination": {
    "has_previous_page": false,
    "has_next_page": true,
    "start_cursor": "WzE0OV0=",
    "end_cursor": "WzI0OV0=",
    "per_page": 100
  }
}

Code Examples

JavaScript

const response = await fetch(
  'https://gateway.maton.ai/kit/v4/subscribers?per_page=10',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();

Python

import os
import requests

response = requests.get(
    'https://gateway.maton.ai/kit/v4/subscribers',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'per_page': 10}
)
data = response.json()

Notes

Kit API uses V4 (V3 is deprecated)

Subscriber IDs are integers

Custom field keys are auto-generated from labels

Bulk operations (>100 items) are processed asynchronously

Delete operations return 204 No Content with empty body

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 Kit connection |

| 401 | Invalid or missing Maton API key |

| 403 | Insufficient permissions (check OAuth scopes) |

| 404 | Resource not found |

| 429 | Rate limited |

| 4xx/5xx | Passthrough error from Kit 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://ctrl.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 `kit`. For example:

Correct: `https://gateway.maton.ai/kit/v4/subscribers`

Incorrect: `https://gateway.maton.ai/v4/subscribers`
