| Application | 100,000 requests/day |
Notes
- Person IDs are unique per application and not transferable across apps
- The
authorfield 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: 202506header for all REST API calls - Profile picture URLs may expire; re-fetch if needed
- IMPORTANT: When using curl commands, use
curl -gwhen URLs contain brackets to disable glob parsing - IMPORTANT: When piping curl output to
jqor other commands, environment variables like$MATON_API_KEYmay not expand correctly in some shell environments
Error Handling

Troubleshooting: API Key Issues
- Check that the
MATON_API_KEYenvironment 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://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
- 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

# 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",

"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.

## Getting Your Person ID
To create posts, you need your LinkedIn person ID. 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 |
