Table of contents
At its heart, Ghost is a RESTful JSON API — designed to create, manage and retrieve publication content with ease. Ghost's API is split by function into two parts: Content and Admin. Each has its own authentication methods, structure and extensive tooling so that common publication use cases are solved with minimal effort.
Whether you want to publish content from your favourite desktop editor, build a custom interface for handling editorial workflow, share your most recent posts on your marketing site, or use Ghost as a full headless CMS, Ghost has the tools to support you.
Ghost's public Content API is what delivers published content to the world and can be accessed in a read-only manner by any client to render in a website, app or other embedded media.
Access control is managed via an API key, and even the most complex filters are made simple with our query language. The Content API is designed to be fully cachable, meaning you can fetch data as often as you like without limitation.
Managing content is done via Ghost's Admin API, which has both read and write access used to create and update content.
The Admin API provides secure role-based authentication so that you can publish from anywhere with confidence, either as a staff user via session authentication or via an integration with a third-party service.
When authenticated with the admin or owner role, the Admin API provides full control for creating, editing and deleting all data in your publication, giving you even more power and flexibility than the standard Ghost admin client.
It provides tools for working with API data to accomplish common use cases such as returning a list of tags for a post, rendering meta data in the
<head>, and outputting data with sensible fallbacks.
Notify an external service when content has changed or been updated by calling a configured HTTP endpoint. This makes it a breeze to do things like trigger a rebuild in a static site generator, or notify Slack that something happened.
By combining Webhooks and the API it is possible to integrate into any aspect of your content lifecycle, to enable a wide range of content distribution and workflow automation use cases.
Each major version of Ghost ships with multiple versions of the APIs. We maintain a stability index so that you can be sure about depending on them in production.
Ghost major versions ship every 8-12 months, meaning code you write against our API today will be stable for a minimum of 2 years.
