# 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.

### Media Upload (REST API)

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

#### Initialize Image Upload

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

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

**Response:**
```json
{
  "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:**

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

GATEWAY = 'https://gateway.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 (`gateway.maton.ai/linkedin/...`) — the gateway 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

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

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

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

### Ad Targeting

#### Get Available Targeting Facets

```bash
GET /linkedin/rest/adTargetingFacets
```

Returns all available targeting facets for ad campaigns (31 facets including employers, degrees, skills, locations, industries, etc.).

**Response:**
```json
{
  "elements": [
    {
      "facetName": "skills",
      "adTargetingFacetUrn": "urn:li:adTargetingFacet:skills",
      "entityTypes": ["SKILL"],
      "availableEntityFinders": ["AD_TARGETING_FACET", "TYPEAHEAD"]
    },
    {
      "facetName": "industries",
      "adTargetingFacetUrn": "urn:li:adTargetingFacet:industries"
    }
  ]
}
```

Available targeting facets include:
- `skills` - Member skills
- `industries` - Industry categories
- `titles` - Job titles
- `seniorities` - Seniority levels
- `degrees` - Educational degrees
- `schools` - Educational institutions
- `employers` / `employersPast` - Current/past employers
- `locations` / `geoLocations` - Geographic targeting
- `companySize` - Company size ranges
- `genders` - Gender targeting
- `ageRanges` - Age range targeting

## 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')

```

## 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 |

## Little Text Format (Commentary Field)

The `commentary` field in posts uses LinkedIn's "Little Text Format". **Reserved characters must be escaped with a backslash or the post content will be truncated.**

### Reserved Characters (Must Escape)

| Character | Escape As |
|-----------|-----------|
| `\` | `\\` |
| `\|` | `\\|` |
| `{` | `\{` |
| `}` | `\}` |
| `@` | `\@` |
| `[` | `\[` |
| `]` | `\]` |
| `(` | `$` |
| `)` | `$` |
| `<` | `\<` |
| `>` | `\>` |
| `#` | `\#` |
| `*` | `\*` |
| `_` | `\_` |
| `~` | `\~` |

### Example

```json
{
  "commentary": "Hello\\! Check out these bullet points:\\n\\n\\* Point 1\\n\\* Point 2\\n\\* More info \$details inside\$"
}
```

### 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

```python
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

## 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 |
