Quick Start

# Get current user profile
python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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://api.maton.ai/linkedin/rest/{resource}

Maton 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

Sign in or create an account at maton.ai
Go to maton.ai/settings
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://api.maton.ai.

List Connections

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": "2026-02-07T08:00:24.372659Z",
    "last_updated_time": "2026-02-07T08:05:16.609085Z",

    "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://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 LinkedIn 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/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', '{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 posts, profiles, organizations, images, videos, and analytics within the connected LinkedIn 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.

Media Upload (REST API)

The REST API provides modern media upload endpoints. All require version header LinkedIn-Version: 202506.

Initialize Image Upload

POST /linkedin/rest/images?action=initializeUpload
Content-Type: application/json
LinkedIn-Version: 202506

{
  "initializeUploadRequest": {
    "owner": "urn:li:person:{personId}"
  }
}

Response:

{
  "value": {
    "uploadUrlExpiresAt": 1770541529250,
    "uploadUrl": "https://www.linkedin.com/dms-uploads/...",
    "image": "urn:li:image:D4D10AQH4GJAjaFCkHQ"
  }
}

Use the uploadUrl to PUT your image binary, then use the image URN in your post.

Create a Video Post

Video uploads are a 4-step process: initialize, upload binary, finalize, then create the post.

CRITICAL — URL Encoding: The upload URL returned by the initialize step contains URL-encoded characters (e.g., %253D) that get corrupted when passed through shell variables or curl. You MUST use Python urllib for the entire flow — parse the JSON response and use the URL directly in Python without passing it through the shell. This is the only reliable approach.

Complete working example:

python <<'EOF'
import urllib.request, os, json

GATEWAY = 'https://api.maton.ai'
HEADERS = {
    'Authorization': f'Bearer {os.environ["MATON_API_KEY"]}',
    'Content-Type': 'application/json',
    'LinkedIn-Version': '202506',
    'X-Restli-Protocol-Version': '2.0.0',
}

# Step 0: Get person ID
req = urllib.request.Request(f'{GATEWAY}/linkedin/rest/me')
for k, v in HEADERS.items(): req.add_header(k, v)
person_id = json.load(urllib.request.urlopen(req))['id']
owner = f'urn:li:person:{person_id}'

# Step 1: Initialize upload (via gateway)
file_path = '/path/to/video.mp4'
file_size = os.path.getsize(file_path)

init_data = json.dumps({
    'initializeUploadRequest': {
        'owner': owner,
        'fileSizeBytes': file_size,
        'uploadCaptions': False,
        'uploadThumbnail': False,
    }
}).encode()

req = urllib.request.Request(f'{GATEWAY}/linkedin/rest/videos?action=initializeUpload', data=init_data, method='POST')
for k, v in HEADERS.items(): req.add_header(k, v)
init_resp = json.load(urllib.request.urlopen(req))
upload_url = init_resp['value']['uploadInstructions'][0]['uploadUrl']
video_urn = init_resp['value']['video']

# Step 2: Upload binary DIRECTLY to LinkedIn's pre-signed URL (NOT through the gateway)
# The upload URL points to www.linkedin.com — it is pre-signed and needs NO Authorization header.
# IMPORTANT: Use the URL exactly as returned by json.load() — do NOT pass it through shell variables.
with open(file_path, 'rb') as f:
    video_data = f.read()

upload_req = urllib.request.Request(upload_url, data=video_data, method='PUT')
upload_req.add_header('Content-Type', 'application/octet-stream')
upload_resp = urllib.request.urlopen(upload_req)
etag = upload_resp.headers['etag']

# Step 3: Finalize upload (via gateway)
finalize_data = json.dumps({
    'finalizeUploadRequest': {
        'video': video_urn,
        'uploadToken': '',
        'uploadedPartIds': [etag],
    }
}).encode()

req = urllib.request.Request(f'{GATEWAY}/linkedin/rest/videos?action=finalizeUpload', data=finalize_data, method='POST')
for k, v in HEADERS.items(): req.add_header(k, v)
urllib.request.urlopen(req)

# Step 4: Create post with video (via gateway)
post_data = json.dumps({
    'author': owner,
    'lifecycleState': 'PUBLISHED',
    'visibility': 'PUBLIC',
    'commentary': 'Check out this video!',
    'distribution': {'feedDistribution': 'MAIN_FEED'},
    'content': {'media': {'id': video_urn}},
}).encode()

req = urllib.request.Request(f'{GATEWAY}/linkedin/rest/posts', data=post_data, method='POST')
for k, v in HEADERS.items(): req.add_header(k, v)
resp = urllib.request.urlopen(req)
print(f'Video post created! {resp.headers.get("location")}')
EOF

How it works:

Steps 1, 3, 4 go through the gateway (api.maton.ai/linkedin/...) — Maton injects your OAuth token automatically.
Step 2 goes directly to LinkedIn's pre-signed upload URL (www.linkedin.com/dms-uploads/...) — no auth header needed, no gateway.
The etag from the upload response is required for the finalize step.
For large videos (>4MB), LinkedIn returns multiple uploadInstructions — upload each chunk to its respective URL and collect all etags.

Video specifications:

Length: 3 seconds to 30 minutes
File size: 75KB to 500MB
Format: MP4

Initialize Document Upload

POST /linkedin/rest/documents?action=initializeUpload
Content-Type: application/json
LinkedIn-Version: 202506

{
  "initializeUploadRequest": {
    "owner": "urn:li:person:{personId}"
  }
}

Response:

{
  "value": {
    "uploadUrlExpiresAt": 1770541530896,
    "uploadUrl": "https://www.linkedin.com/dms-uploads/...",
    "document": "urn:li:document:D4D10AQHr-e30QZCAjQ"
  }
}

Ad Targeting

Get Available Targeting Facets

GET /linkedin/rest/adTargetingFacets

Response:

{
  "elements": [
    {
      "facetName": "skills",
      "adTargetingFacetUrn": "urn:li:adTargetingFacet:skills",
      "entityTypes": ["SKILL"],

    },
    {
      "facetName": "industries",
      "adTargetingFacetUrn": "urn:li:adTargetingFacet:industries"

Getting Your Person ID

To create posts, you need your LinkedIn person ID. Get it from the /rest/me endpoint:

python <<'EOF'
import urllib.request, os, json
req = urllib.request.Request('https://api.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

Mentions and Hashtags

Use Little Text Format syntax for mentions and hashtags:

Mention a person: @[Display Name](urn:li:person:123)
Mention an organization: @[Company Name](urn:li:organization:456)
Hashtag (template): {hashtag|\\#|MyTag}
Hashtag (simple): #hashtag (single words only)

Python Helper Function

def escape_linkedin_commentary(text):
    """Escape reserved characters for LinkedIn Little Text Format."""
    reserved = ['\\', '|', '{', '}', '@', '[', ']', '(', ')', '<', '>', '#', '*', '_', '~']
    for char in reserved:
        text = text.replace(char, '\\' + char)
    return text

# Usage
commentary = escape_linkedin_commentary("Check this out! Details (inside) #tech")
# Result: "Check this out\\! Details \\(inside\\) \\#tech"

Notes

Person IDs are unique per application and not transferable across apps
Commentary uses Little Text Format — escape reserved characters (\|{}@[]()<>#*_~) with backslash or content will be truncated
The author field must use URN format: urn:li:person:{personId}
All posts require lifecycleState: "PUBLISHED"
Image uploads are a 3-step process: initialize, upload binary, create post
Video uploads are a 4-step process: initialize, upload binary, finalize, create post
Media upload URLs (images, videos, documents) point to www.linkedin.com, NOT api.linkedin.com. These are pre-signed URLs that do NOT go through the gateway and do NOT require an Authorization header. You MUST use Python urllib to handle these URLs — do NOT pass them through shell variables or use curl, as the URL contains encoded characters (%253D) that get corrupted by shell expansion.
Include LinkedIn-Version: 202506 header for all REST API calls
Profile picture URLs may expire; re-fetch if needed

Troubleshooting: API Key Issues

Check that the MATON_API_KEY environment variable is set:

echo $MATON_API_KEY

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

Ensure your URL path starts with linkedin. For example:

Correct: https://api.maton.ai/linkedin/rest/me
Incorrect: https://api.maton.ai/rest/me
