# Lemlist

Access the Lemlist API with managed OAuth authentication. Manage campaigns, leads, activities, schedules, sequences, and unsubscribes for sales automation and cold outreach.

Quick Start

# List campaigns
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/lemlist/api/campaigns')
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/lemlist/api/{resource}

Replace `{resource}` with the actual Lemlist API endpoint path. The gateway proxies requests to `api.lemlist.com/api` 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 Lemlist 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=lemlist&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': 'lemlist'}).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": "3ecf268f-42ad-40cc-b77a-25e020fbf591",
    "status": "ACTIVE",
    "creation_time": "2026-02-12T02:00:53.023887Z",
    "last_updated_time": "2026-02-12T02:01:45.284131Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "lemlist",
    "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 Lemlist 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/lemlist/api/campaigns')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('Maton-Connection', '3ecf268f-42ad-40cc-b77a-25e020fbf591')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

Code Examples

JavaScript - List Campaigns

const response = await fetch(
  'https://gateway.maton.ai/lemlist/api/campaigns',
  {
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`
    }
  }
);
const campaigns = await response.json();
console.log(campaigns);

Python - List Campaigns

import os
import requests

response = requests.get(
    'https://gateway.maton.ai/lemlist/api/campaigns',
    headers={'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
)
campaigns = response.json()
for campaign in campaigns:
    print(f"{campaign['name']}: {campaign['_id']}")

Python - Create Campaign and Add Lead

import os
import requests

headers = {'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}'}
base_url = 'https://gateway.maton.ai/lemlist/api'

# Create campaign
campaign_response = requests.post(
    f'{base_url}/campaigns',
    headers=headers,
    json={'name': 'Q1 Outreach'}
)
campaign = campaign_response.json()
print(f"Created campaign: {campaign['_id']}")

# Add lead to campaign

Notes

Rate Limits

| Operation | Limit |

|-----------|-------|

| API calls | 20 per 2 seconds per API key |

When rate limited, implement exponential backoff for retries.

Error Handling

| Status | Meaning |

|--------|---------|

| 400 | Bad request or missing Lemlist connection |

| 401 | Invalid or missing Maton API key |

| 404 | Resource not found |

| 405 | Method not allowed |

| 422 | Validation error |

| 429 | Rate limited |

| 4xx/5xx | Passthrough error from Lemlist 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 `lemlist`. For example:
