Ghost: posting rules and settings

What a Ghost channel accepts in Postemi: media, limits, required fields, and the fields of the settings object for the API.

Basics

Rules

• You connect with the API URL and the Admin API key of a custom integration (Ghost Admin > Settings > Integrations).
• Postemi creates the post at the scheduled time. It sends no newsletter.
• Beta: not yet tested with many sites.

Settings fields

These fields go into the post's settings object, alongside the __type field. In the UI, you fill in the same ones in the channel's settings section.

Examples

Each example is one item in the POST /public/v1/posts request's posts array. The envelope around it is always this:

{
  "type": "schedule",
  "date": "2026-09-15T09:00:00.000Z",
  "shortLink": false,
  "posts": [ /* the item below */ ]
}

{
  "integration": { "id": "<channel-id>" },
  "value": [{ "content": "<p>The text of the post.</p>", "image": [] }],
  "settings": { "__type": "ghost" }
}

The channel ID comes from the channel list, and the path values for images and videos from media upload. The exact schema for the connected account comes from the settings schema endpoint. From the command line, the same thing is the --settings flag. See the CLI examples.
