[Platform guide](https://docs.openpo.st/providers/linkedin) Formats and limits ## Different formats, different rules. OpenPost checks the text and media rules for the format you choose. | Format | Text | Media | | --- | --- | --- | | Post or link | 3,000 characters | Text or a link card | | Comment thread | 1,250 characters per child | Text only | | Image, document, or video | 3,000 characters | One image, PDF document, or video per account version | ### Provider limits and scope - 3000 characters for posts - 1,250 characters for thread comments - One image, video, or document, or 2-20 images - Thread children publish as comments Connect and test ## Set up LinkedIn in three checks. 1. Configure the LinkedIn client ID, secret, and callback URL. 1. Confirm the app has the publishing products and permissions you need. 1. Connect the member or organization account and test each approved media type. Known limits ## What can still block a post. - Publishing and comment permissions depend on LinkedIn products, scopes, and app review. - Documents use the LinkedIn Documents API and require a title. - Organization posting depends on the connected member role and granted access. **Account requirement:** A LinkedIn developer app with the publishing products and scopes your account needs. **Verification:** OAuth success alone does not prove every publishing permission; test the formats your team will schedule. ## Use the current callback address, permissions, and media setup. Social network developer pages change. The OpenPost guide lists the settings and checks you need now. [Read the LinkedIn guide](https://docs.openpo.st/providers/linkedin)
