LinkedIn

Access the LinkedIn API with managed OAuth authentication. Share posts, manage advertising campaigns, retrieve profile and organization information, upload media, and access the Ad Library.

Quick Start

# Get current user profile
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://gateway.maton.ai/linkedin/rest/me')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('LinkedIn-Version', '202506')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

Base URL

https://gateway.maton.ai/linkedin/rest/{resource}

The gateway proxies requests to api.linkedin.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

Required Headers

LinkedIn REST API requires the version header:

LinkedIn-Version: 202506

Connection Management

Manage your LinkedIn 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=linkedin&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': 'linkedin'}).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": "ba10eb9e-b590-4e95-8c2e-3901ff94642a",
    "status": "ACTIVE",
    "creation_time": "2026-02-07T08:00:24.372659Z",
    "last_updated_time": "2026-02-07T08:05:16.609085Z",
    "url": "https://connect.maton.ai/?session_token=...",
    "app": "linkedin",
    "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 LinkedIn 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/linkedin/rest/me')
req.add_header('Authorization', f'Bearer {os.environ["MATON_API_KEY"]}')
req.add_header('LinkedIn-Version', '202506')
req.add_header('Maton-Connection', 'ba10eb9e-b590-4e95-8c2e-3901ff94642a')
print(json.dumps(json.load(urllib.request.urlopen(req)), indent=2))
EOF

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

Code Examples

const personId = 'YOUR_PERSON_ID';

const response = await fetch(
  'https://gateway.maton.ai/linkedin/rest/posts',
  {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MATON_API_KEY}`,
      'Content-Type': 'application/json',
      'LinkedIn-Version': '202506'
    },
    body: JSON.stringify({
      author: `urn:li:person:${personId}`,
      lifecycleState: 'PUBLISHED',
      visibility: 'PUBLIC',
      commentary: 'Hello from the API!',
      distribution: {
        feedDistribution: 'MAIN_FEED'
      }
    })
  }
);

Python - Create Text Post

import os
import requests

person_id = 'YOUR_PERSON_ID'

response = requests.post(
    'https://gateway.maton.ai/linkedin/rest/posts',

    }
)

Rate Limits

Throttle Type Daily Limit (UTC)
Member 150 requests/day
Application 100,000 requests/day

Notes

  • Person IDs are unique per application and not transferable across apps
  • The author field must use URN format: urn:li:person:{personId}
  • All posts require lifecycleState: "PUBLISHED"
  • Image/video uploads are a 3-step process: initialize upload, upload binary, create post
  • Include LinkedIn-Version: 202506 header for all REST API calls
  • Profile picture URLs may expire; re-fetch if needed
  • 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

}

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://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 linkedin. For example:
  • Correct: https://gateway.maton.ai/linkedin/rest/me
  • Incorrect: https://gateway.maton.ai/rest/me

OAuth Scopes
