What the user needs

Any LinkedIn member can connect their personal profile. Company pages appear only for pages the connecting member administers. One connect can therefore create several accounts at once: the personal profile, plus one per page.
Page accounts are not in the redirect
The OAuth redirect returns only the personal profile's accountId. Call GET /api/v1/accounts afterwards to find the page accounts — their platformUserId reads organization:{id}. Each is targeted exactly like any other account.
If a member is made admin of a new page later, they need to reconnect before it appears.

Publishing behaviour

  • Text up to 3,000 characters — the most generous of the four.
  • One image publishes as a single-media post; 2–10 as a multi-image post.
  • One video, or images — never both in the same post.
LinkedIn treats several characters as formatting controls. Chirio escapes them for you, so brackets and punctuation in your copy come out as written. #hashtags pass through untouched.

First comments

Supported, up to 1,250 characters, posted as the same author as the post.
A LinkedIn comment failure is not fixed by reconnecting
Unlike Instagram and Threads, a permission refusal here is an authorisation Chirio holds with LinkedIn, not something your user's connection can grant. Publishing keeps working normally. Contact support rather than sending your user through the connect flow again.

Connection lifetime

LinkedIn issues long-lived refresh credentials only to integrations it has specifically approved for it. In the common case a LinkedIn connection therefore needs re-authorising roughly every 60 days, rather than being refreshed indefinitely in the background. Plan for it: check status on GET /api/v1/accounts and prompt the user before a campaign rather than after a failure. See Account lifecycle.
