Chatgpt Grow

Connect your Ghost site

Chatgpt Grow publishes to Ghost through the Admin API, authenticated with a custom integration’s Admin API key. It works with Ghost(Pro) and self-hosted Ghost, and you can revoke the key from the same screen at any time.

Before you start

  • A Ghost site you can sign in to as an Owner or Administrator.
  • Your Ghost site root, for example https://yourblog.com — the public address, not the /ghost admin address.
  • A site reachable from the internet. Publishing happens server to server, so a Ghost instance running only on your laptop cannot be connected.

    Copy the Admin API key

    Ghost shows a Content API key and an Admin API key. Copy the Admin API key: an ID and a secret joined by a colon.

    • Take the whole string, including the colon and the secret after it.
    • The Content API key looks similar and will be rejected. If in doubt, create a new integration and copy again.

Official Ghost documentation

Connect it in Chatgpt Grow

Two credential fields, plus an optional name for the connection. The API key is the one people get wrong — it must be the Admin API key, in full.

Admin API URL

Your Ghost site root. Do not append /ghost and do not add a trailing slash.

Optional. A name for this connection so you can tell it apart later.

What happens after you connect

  • Chatgpt Grow creates a Ghost post and sets it to Published — it goes live immediately.
  • The body is sent as HTML and Ghost converts it into its native editor format, so you can keep editing it in Ghost.
  • If the article has a hero image, it is set as the post’s feature image.
  • Only one platform can be connected at a time. To publish somewhere else, disconnect Ghost first.

Troubleshooting

  • Status 401, or "invalid token"

    You copied the Content API key, or the key is missing the colon and the secret after it. Re-copy the Admin API key whole. If you already closed the panel, create a new integration — Ghost does not show the secret again.

  • Status 404

    The site URL is wrong, or it points at the /ghost admin address. Use the public site root, for example https://yourblog.com.

  • The connection times out

    The Ghost site is not reachable from the internet — typical for a Ghost instance running locally or behind a firewall. Publishing is server to server, so the site has to be publicly reachable.

  • A version or compatibility error

    Older Ghost releases may not support the Admin API version Chatgpt Grow uses. Update Ghost, then reconnect.
