name: active-campaign description: | ActiveCampaign API integration with managed OAuth. Marketing automation, CRM, contacts, deals, and email campaigns. Use this skill when users want to manage contacts, deals, tags, lists, automations, or campaigns in ActiveCampaign. For other third party apps, use the api-gateway skill (https://clawhub.ai/byungkyu/api-gateway). Requires network access and valid Maton API key. metadata: author: maton version: "1.0" clawdbot: emoji: 🧠 homepage: "https://maton.ai" requires: env: - MATON_API_KEY

ActiveCampaign

Access the ActiveCampaign API with managed OAuth authentication. Manage contacts, deals, tags, lists, automations, and email campaigns.

Quick Start

# List all contacts
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/active-campaign/api/3/contacts')
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/active-campaign/{native-api-path}

Replace {native-api-path} with the actual ActiveCampaign API endpoint path. The gateway proxies requests to {account}.api-us1.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 ActiveCampaign 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=active-campaign&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': 'active-campaign'}).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": "9e8ba2aa-25ec-4ba0-8815-3068be304dca",
    "status": "ACTIVE",
    "creation_time": "2026-02-09T20:03:16.595823Z",
    "last_updated_time": "2026-02-09T20:04:09.550767Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "active-campaign",
    "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 ActiveCampaign 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/active-campaign/api/3/contacts')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '9e8ba2aa-25ec-4ba0-8815-3068be304dca')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

• offset - Starting index

Response includes meta:

{
  "contacts": [...],

For large datasets, use orders[id]=ASC and id_greater parameter for better performance:

GET /active-campaign/api/3/contacts?orders[id]=ASC&id_greater=100

Code Examples

JavaScript

const response = await fetch(
  'https://gateway.maton.ai/active-campaign/api/3/contacts',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const data = await response.json();
console.log(data.contacts);

Python

import os
import requests

response = requests.get(
    'https://gateway.maton.ai/active-campaign/api/3/contacts',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
data = response.json()
print(data['contacts'])

Python (Create Contact with Tag)

import os
import requests

headers = {
    'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
    'Content-Type': 'application/json'
}

# Create contact
contact_response = requests.post(
    'https://gateway.maton.ai/active-campaign/api/3/contacts',
    headers=headers,
    json={
        'contact': {
            'email': 'newuser@example.com',
            'firstName': 'New',
            'lastName': 'User'
        }
    }
)
contact = contact_response.json()['contact']
print(f"Created contact ID: {contact['id']}")

# Add tag to contact
tag_response = requests.post(
    'https://gateway.maton.ai/active-campaign/api/3/contactTags',
    headers=headers,
    json={
        'contactTag': {
            'contact': contact['id'],
            'tag': '1'
        }
    }
)
print("Tag added to contact")

Notes

• All endpoints require the /api/3/ prefix
• Request bodies use singular resource names wrapped in an object (e.g., {"contact": {...}})
• IDs are returned as strings
• Timestamps are in ISO 8601 format with timezone
• Rate limit: 5 requests per second per account
• DELETE operations return 200 OK (not 204)
• 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

Error responses include details:

{
  "errors": [
    {
      "title": "The contact email is required",
      "source": {
        "pointer": "/data/attributes/email"
      }
    }
  ]
}

Troubleshooting: Invalid API Key

When you receive an "Invalid API key" error, ALWAYS follow these steps before concluding there is an issue:

1. Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

1. 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
