FAQ

Common questions

Can I post to LinkedIn Company Pages?
Yes, if your account has admin access to the page. Connect the page via OAuth and use its account_id in API calls.
Does LinkedIn support video posts?
Yes. UniPost supports LinkedIn text, image, and single-video posts through the same POST /v1/posts endpoint.
How do I publish a local image or video file?
If the asset already has a public URL, send it in media_urls. If it lives on disk, first upload it with POST /v1/media, PUT the bytes to the returned upload_url, then publish with media_ids.
Do I need LinkedIn developer access?
In Quickstart mode, no — UniPost's credentials handle everything. In White-label mode, you'll need your own LinkedIn app.
How long does setup take?
About 5 minutes in Quickstart mode. Connect your LinkedIn account via OAuth and start posting immediately.
What happens when my token expires?
UniPost automatically refreshes LinkedIn tokens in the background. You never need to re-authenticate.
Is LinkedIn included in the free plan?
Yes. The free plan includes 100 posts/month across 8 Free-tier platforms including LinkedIn.
