LinkedIn

LinkedIn posting uses an OAuth access token and a member or organization identity.

Content support

Capability	Support
Text	Up to 3000 characters.
Images	Up to 9 images.
Video	One video.
Mixed media	Not supported.
Empty posts	Not allowed; provide text or media.

Set up credentials

1. Create a LinkedIn app in the LinkedIn Developer portal.
2. Request the products and permissions needed for posting (w_member_social, plus openid, profile, email if you need login data).
3. Configure OAuth redirect URIs for your app or Scheduler deployment.
4. Run the OAuth authorization flow.
5. Store the access token and member ID or page/organization ID.
6. Confirm the token has posting permissions before using it in automation.

The CLI does not bundle a LinkedIn OAuth app. To use it from the CLI, supply your own client secret through SIMPLE_POST_LINKEDIN_CLIENT_SECRET before running simplepost account add linkedin.

Environment variables

LINKEDIN_ACCESS_TOKEN=
LINKEDIN_MEMBER_ID=

Both variables must be set together.
