Why not just use Slack's built-in options? Even where Ghost offers some form of Slack integration, it's often tied to one account, limited in which events it covers, or more than you need. ZestyGlue is a dedicated, always-on feed of exactly the events you choose, for $9/month instead of a full automation-platform subscription.
What it looks like
A real Ghost event, shown as ZestyGlue formats it for Slack.
Setup — about two minutes
- Create the connector. In ZestyGlue, start a new Ghost → Slack connector. You'll get a unique webhook URL right away.
- Point Ghost at it. In Ghost Admin, go to Integrations → Add custom integration → Add webhook, pick an event, and paste in your ZestyGlue webhook URL.
- (Optional) set a secret. Ghost can sign its payloads if you configure a secret on the integration — enter the same value into ZestyGlue for extra verification, though it isn't required to get started.
- Point Slack at ZestyGlue. Create a Slack app (or reuse one) → Incoming Webhooks → Add New Webhook to Workspace, pick the channel, and copy the URL into ZestyGlue.
Tip: Ghost's webhook payload shape differs by event — a member event nests data under member.current, a post event under post.current. ZestyGlue detects which one it received automatically.
Events you can forward
member.added
member.edited
post.published
post.updated
Questions
Is my Ghost Webhook Secret safe with ZestyGlue?
It's encrypted at rest with Fernet symmetric encryption before it ever touches disk, it's never logged, and it's never displayed again in the dashboard after you enter it — only a masked placeholder is shown.
Will this work for a self-hosted Ghost instance, not just Ghost(Pro)?
Yes — Ghost's webhook feature works the same way self-hosted or on Ghost(Pro); it just needs to reach zestyglue.com over the internet.
Can I get notified about both new members and new posts?
Yes, but as two separate connectors — each Ghost webhook is scoped to one event type.
Does this need Slack admin approval?
No app installation is required on Slack's side — an Incoming Webhook is just a URL generated once. No OAuth review, no admin approval flow.
What happens if my ZestyGlue subscription lapses?
Events are silently dropped rather than causing errors on Ghost's side — Ghost never sees a failure response, so it won't retry aggressively or flag your webhook as broken. Your dashboard will simply stop showing new events until you resubscribe.
