  title: LinkedIn Upload an Image and Create a Post
  summary: Register an image upload, confirm the image asset, then publish a post that references it.
  description: >-
    Creating a rich post with an image on LinkedIn is a register-then-publish
    pattern. This workflow initializes an image upload to obtain an image URN,
    verifies that the image asset resolves, and then creates a post that
    references the uploaded image as its media. Every step spells out its request
    inline, including the Authorization bearer token and the required
    LinkedIn-Version header, so the flow can be read and executed without opening
    the underlying OpenAPI description.
