Can Postly publish directly to Ghost?

Yes. Connect Ghost with a Custom Integration Admin API key, then publish now or schedule the article.

Does Postly support self-hosted Ghost and Ghost(Pro)?

Yes. Self-hosted Ghost is supported, and Ghost(Pro) is supported on plans that include Custom Integrations and the Admin API.

Use the Admin API key from Ghost Admin → Settings → Integrations. Do not use the Content API key.

No. Ghost is currently a publishing channel; its stable integration-token Admin API does not provide the comments workflow Postly CRM requires.

Publish Ghost articles with canonical URLs, search metadata, Open Graph fields, featured images, tags, and member visibility.
