In short
Social Relay publishes to LinkedIn personal (member) profiles only. Connect with platforms including linkedin; posts use the member’s profile as author. Company / organization Page posting is not available. Text limits are about 3,000 characters; hard posting quota is about 150 posts per day per account.
Scope (what is supported)
v1 LinkedIn support is personal profile posting only. End users authorize with Share on LinkedIn scopes (openid, profile, email, w_member_social). The connection binds their member URN; publish legs post as that person.
- API platform key: linkedin
- Supported: personal LinkedIn profile
- Not supported: LinkedIn Company Pages (organization authors)
Connect and publish
Include linkedin in the connect session platforms array. After OAuth, the profile has a linkedin connection. Create posts with platforms: ["linkedin"] (and other networks as needed). Do not rely on organizationId or Company Page selection—those are not product features today.
Media and documents
Images, multi-image, and video are common organic paths. Large document posts and advanced targeting are later depth features—validate what you send.
Reauthorization
LinkedIn tokens may require periodic reauthorization. Plan product UX to re-run connect when connection status indicates refresh is required.
