Overview

Onepostly maps the LinkedIn Posts API (member / Share on LinkedIn) into the same /v1/* surface as other platforms. This section covers LinkedIn-only behavior.

Company Pages are not supported in this release — only the authenticated member’s personal profile.

In this section

Page	Topics
Posts	Publish text, image, multi-image, video; schedule; remote delete

Cross-platform API flow: Media, Webhooks.

Connect

Dashboard → Connections → connect LinkedIn
Approve scopes in the LinkedIn consent screen
Resolve connectionId with your API key:

curl https://api.onepostly.com/v1/connections \
  -H "x-api-key: op_YOUR_KEY"

Use the matching row’s id (where platform is "linkedin") as connectionId in publish requests.

OAuth scopes

Scope	Used for
`openid` / `profile`	Person URN + display name (Sign In with LinkedIn using OpenID Connect)
`w_member_social`	Publish posts, upload images/videos, delete (Share on LinkedIn)

OAuth 2.0 authorization code. Access tokens last about 60 days; reconnect before expiry if LinkedIn does not issue a refresh token for your app.

Auth errors

Code	Meaning
`TOKEN_INVALID` / `401`	Expired or invalid token → reconnect
`PERMISSION_DENIED` / `403`	Missing scope → reconnect with Share on LinkedIn + OpenID Connect
