Use this skill when users want to share content on LinkedIn, manage ad campaigns, get profile/organization information, or interact with LinkedIn's platform. 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: 🧠 requires: env: - MATON_API_KEY --- # 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 ```bash # 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`: ```bash 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 ```bash 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 ```bash 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 ```bash 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:** ```json { "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 ```bash 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: ```bash 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. ## API Reference ### Profile #### Get Current User Profile ```bash GET /linkedin/rest/me LinkedIn-Version: 202506 ``` **Example:** ```bash 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 ``` **Response:** ```json { "firstName": { "localized": {"en_US": "John"}, "preferredLocale": {"country": "US", "language": "en"} }, "localizedFirstName": "John", "lastName": { "localized": {"en_US": "Doe"}, "preferredLocale": {"country": "US", "language": "en"} }, "localizedLastName": "Doe", "id": "yrZCpj2Z12", "vanityName": "johndoe", "localizedHeadline": "Software Engineer at Example Corp", "profilePicture": { "displayImage": "urn:li:digitalmediaAsset:C4D00AAAAbBCDEFGhiJ" } } ``` ### Sharing Posts #### Create a Text Post ```bash POST /linkedin/rest/posts Content-Type: application/json LinkedIn-Version: 202506 { "author": "urn:li:person:{personId}", "lifecycleState": "PUBLISHED", "visibility": "PUBLIC", "commentary": "Hello LinkedIn!

Get it from the `/rest/me` endpoint: ```bash 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') result = json.load(urllib.request.urlopen(req)) print(f"Your person URN: urn:li:person:{result['id']}") EOF ``` ## Code Examples ### JavaScript - Create Text Post ```javascript 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 ```python import os import requests person_id = 'YOUR_PERSON_ID' response = requests.post( 'https://gateway.maton.ai/linkedin/rest/posts', headers={ 'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}', 'Content-Type': 'application/json', 'LinkedIn-Version': '202506' }, json={ 'author': f'urn:li:person:{person_id}', 'lifecycleState': 'PUBLISHED', 'visibility': 'PUBLIC', 'commentary': 'Hello from the API!', 'distribution': { 'feedDistribution': 'MAIN_FEED' } } ) ``` ## 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 ## Error Handling | Status | Meaning | |--------|---------| | 400 | Missing LinkedIn connection or invalid request | | 401 | Invalid or missing Maton API key | | 403 | Insufficient permissions (check OAuth scopes) | | 404 | Resource not found | | 422 | Invalid request body or URN format | | 429 | Rate limited | | 4xx/5xx | Passthrough error from LinkedIn API | ### Error Response Format ```json { "status": 403, "serviceErrorCode": 100, "code": "ACCESS_DENIED", "message": "Not enough permissions to access resource" } ``` ### Troubleshooting: API Key Issues 1. Check that the `MATON_API_KEY` environment variable is set: ```bash echo $MATON_API_KEY ``` 2. Verify the API key is valid by listing connections: ```bash 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 | ## Resources - [LinkedIn API Overview](https://learn.microsoft.com/en-us/linkedin/) - [Share on LinkedIn Guide](https://learn.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/share-on-linkedin) - [Profile API](https://learn.microsoft.com/en-us/linkedin/shared/integrations/people/profile-api) - [Sign In with LinkedIn](https://learn.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/sign-in-with-linkedin-v2) - [Authentication Guide](https://learn.microsoft.com/en-us/linkedin/shared/authentication/authentication) - [Marketing API](https://learn.microsoft.com/en-us/linkedin/marketing/) - [Ad Accounts](https://learn.microsoft.com/en-us/linkedin/marketing/integrations/ads/account-structure/create-and-manage-accounts) - [Campaign Management](https://learn.microsoft.com/en-us/linkedin/marketing/integrations/ads/account-structure/create-and-manage-campaigns) - [Ad Library API](https://www.linkedin.com/ad-library/api/) - [Maton Community](https://discord.com/invite/dBfFAcefs2) - [Maton Support](mailto:support@maton.ai)
