Keap

Access the Keap API with managed OAuth authentication. Manage contacts, companies, tags, tasks, orders, opportunities, campaigns, and more for CRM and marketing automation.

Quick Start

# List contacts
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.maton.ai/keap/crm/rest/v2/contacts?page_size=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/keap/crm/rest/{api-path}

Maton proxies requests to api.infusionsoft.com/crm/rest 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 Keap 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=keap&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': 'keap'}).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": "2026-02-08T01:34:44.738374Z",
    "last_updated_time": "2026-02-08T01:35:20.106942Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "keap",
    "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 Keap 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/keap/crm/rest/v2/contacts')
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 contacts, companies, tags, tasks, orders, opportunities, and campaigns for CRM and marketing automation within the connected Keap 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.

Keap uses token-based pagination:

Response:

{
  "contacts": [...],
  "next_page_token": "abc123"
}

For subsequent pages, use the page_token parameter:

GET /keap/crm/rest/v2/contacts?page_size=50&page_token=abc123

When next_page_token is empty, there are no more pages.

Filtering

Use the filter parameter for filtering results:

GET /keap/crm/rest/v2/contacts?filter=given_name==John
GET /keap/crm/rest/v2/contacts?filter=email_addresses.email==john@example.com
GET /keap/crm/rest/v2/tasks?filter=completed==false

Code Examples

JavaScript

const response = await fetch(
  'https://api.maton.ai/keap/crm/rest/v2/contacts?page_size=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/keap/crm/rest/v2/contacts',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'},
    params={'page_size': 10}
)
data = response.json()

Notes

• All API paths must include /crm/rest prefix (e.g., /keap/crm/rest/v2/contacts)
• Keap uses v2 REST API (previous v1 API is deprecated)
• Timestamps are in ISO 8601 format
• IDs are returned as strings
• Pagination uses page_size and page_token (not offset-based)
• Maximum page_size is 1000
• 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

1. 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 keap. For example:

• Correct: https://api.maton.ai/keap/crm/rest/v2/contacts
• Incorrect: https://api.maton.ai/crm/rest/v2/contacts
