Why not just use Slack's built-in options? Even where Supabase 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
ZestyGlue
Supabase — Orders Insert
A real Supabase event, shown as ZestyGlue formats it for Slack.
Setup — about two minutes
- Create the connector. In ZestyGlue, start a new Supabase → Slack connector. You'll get a unique webhook URL right away.
- Point Supabase at it. In your project, go to Database → Webhooks → Create a new hook, pick a table and events, and paste in your ZestyGlue webhook URL.
- (Optional) add a shared token. Add a custom HTTP header named
x-webhook-token with any value you choose, and enter the same value into ZestyGlue for extra verification — not 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.
Under the hood: Supabase Database Webhooks fire directly from Postgres triggers, so events arrive within milliseconds of the actual row change — there's no polling delay anywhere in the pipeline.

Questions
Is my Shared Token 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.
Does this work with Supabase's free tier?
Yes, Database Webhooks are available on Supabase's free plan.
Can I watch multiple tables with one connector?
Each Supabase webhook is scoped to one table's events, so create a separate ZestyGlue connector per table — you can still point several at the same destination.
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 Supabase's side — Supabase 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.
