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](https://maton.ai)

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

Rate Limits

| Throttle Type | Daily Limit (UTC) |

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

| Member | 150 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

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 linkedin. For example:

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

OAuth Scopes

| Scope | Description |

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

| openid | OpenID Connect authentication |

| profile | Read basic profile |

| email | Read email address |

| w_member_social | Create, modify, and delete posts |
