  title: Ghost Admin Authors Site API
  description: The Ghost Admin API provides full read and write access to all content and configuration within a Ghost publication. It enables developers to create, update, and delete posts, pages, tags, members, tiers, newsletters, and offers programmatically. Authentication is handled via JSON Web Tokens generated from an Admin API key, integration tokens, or staff access tokens. The Admin API supports everything the Ghost Admin interface can do and more, making it suitable for building custom publishing workflows, content automation, member management systems, and advanced integrations.
