LinkedIn Feed

NOT YET AVAILABLE -- These endpoints are completely disabled and return HTTP 404 (Not Found). The underlying route handlers are commented out in the source code, so the routes do not exist. They require the r_member_social permission, which is RESTRICTED and requires LinkedIn approval. All request/response formats documented below are planned and speculative -- they are not based on a working implementation and may change when the feature is built. Do not attempt to call these endpoints; they will return a 404 error.

Retrieve your LinkedIn posts, comments, and reactions via the PostPost API.

Caching

All feed retrieval endpoints are cached to reduce API calls:

Endpoint	Cache TTL
Posts	15 minutes
Comments	10 minutes
Reactions	10 minutes

The cached field in responses indicates if data was served from cache.

All feed retrieval endpoints currently return HTTP 404 Not Found because the route handlers are commented out in the source code and the routes do not exist. Express returns its default HTML 404 response (e.g., Cannot POST /api/v1/linkedin-posts), not a JSON body.

Connection Not Found (404)

{
  "error": "LinkedIn connection not found"
}

Verify the platformId matches a connected LinkedIn account.

Invalid URN (400)

{
  "error": "postedId must be a valid LinkedIn URN"
}

Ensure the post URN format is correct (e.g., urn:li:share:123456 or urn:li:ugcPost:123456).
