LinkedIn limitations

LinkedIn's API publishes member posts with firm media specs and a 3,000-character commentary limit. Analytics depth depends on permissions LinkedIn grants per app.

Publishing limits

The limits LinkedIn applies to posts published through its official API. Posty checks every one of these while you compose.

LinkedIn supports multi-image posts via a separate API that Posty doesn't publish to yet.

Rows marked Posty are current Posty product choices rather than hard platform rules.

Analytics

Likes and comments per post; impressions, members reached, reshares, saves and link clicks where LinkedIn's member analytics permission is granted.

  • LinkedIn gates richer post analytics behind an app-level permission - depth varies by what LinkedIn approves.
  • Organization-page statistics use a different API tier aimed at company pages.

Inbox & messaging

LinkedIn provides no DM or comment-management access to standard tools.

  • Messaging APIs are restricted to LinkedIn's enterprise CRM partners.

Good to know

  • No native scheduling - Posty's scheduler publishes at the chosen time.

These limits apply to every tool

They come from LinkedIn's official API, so no scheduler can exceed them. Posty validates against every limit on this page while you compose - if your post passes, LinkedIn will accept it.
