Mentionwell

Ghost is the cleanest CMS to integrate with. Their Admin API was built for exactly this case.

What you need

  • A Ghost site (Ghost(Pro) or self-hosted, version 4 or newer).
  • Admin access.

Setup (2 minutes)

  1. Ghost Admin → Settings → Integrations → Add custom integration.
  2. Name it "Mentionwell".
  3. Copy three values from the integration page:
    • Admin API Key (write access — keep secret)
    • Content API Key (read-only — used for previews)
    • API URL — e.g. https://yoursite.ghost.io
  4. Paste them into Mentionwell's Ghost integration card.
  5. Click Test connection — Mentionwell will create and immediately delete a draft post to verify the credentials work.

Content API = read content. Admin API = create and update. Mentionwell needs the Admin key to publish.

What gets pushed

Mentionwell field Ghost field
Title, slug title, slug
HTML body html (with source: 'html', so Ghost converts to its Lexical format)
Excerpt custom_excerpt (truncated to 300 chars)
Featured image feature_image
Tags + category tags: [{ name }] (auto-created if missing; matched case-insensitively if not)
Author authors: [{ email }] (must be an existing Ghost user)
JSON-LD codeinjection_head
Published date published_at + status: 'published'

Caveats

  • Lexical vs HTML: Ghost 5+ stores posts in Lexical internally. Mentionwell always sends source: 'html' so Ghost converts your HTML on insert. Without that flag, post bodies show up empty in the editor.
  • Newsletters: Ghost can email a post to your subscribers when you publish. By default Mentionwell sets email_only: false and doesn't trigger a send. If you want sends, configure that in Ghost's Newsletter settings — Mentionwell won't override.
  • Authors: Ghost requires the author to be an existing staff user with that email. If the email doesn't match, the post is attributed to the integration owner.
  • Image upload: Ghost will fetch remote feature image URLs. For reliability we upload first via /images/upload and use the returned URL.

Common failures

  • 401 — JWT signed with the wrong secret, or the key was rotated. Generate a new integration key in Ghost.
  • 422 — slug already exists, or a required field is missing. Mentionwell auto-suffixes the slug on retry.
  • 413 — feature image >5MB. Self-hosted Ghost can raise the limit; Ghost(Pro) cannot.
  • 404 — wrong API URL. Don't double-append /ghost/api/admin/ — paste only the site origin.
