  title: Publer API
  description: >-
    The Publer API (v1) lets Publer Business customers programmatically schedule
    and publish social media posts, manage connected social accounts and
    workspaces, work with the media library, and track asynchronous jobs.
    Authentication uses an API key passed as `Authorization: Bearer-API
    YOUR_API_KEY` together with a `Publer-Workspace-Id` header. The API is
    currently available exclusively to Publer Business users.
