Why not call Supabase's API directly from your own endpoint? You can — but then you own Supabase's signature verification, retry handling, and payload quirks yourself. ZestyGlue verifies the signature, normalizes the event into a clean JSON body, and POSTs it to your URL — you only write the part that's actually yours.
What it looks like
ZestyGlue
Supabase — Orders Insert
A real Supabase event, shown as ZestyGlue formats it for Custom Webhook.
Setup — about two minutes
- Create the connector. In ZestyGlue, start a new Supabase → Custom Webhook 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 it at your endpoint. Paste the URL of your own server, script, or automation tool's webhook receiver — no signup, no app to install.
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.
Events you can forward

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.
Do I need to write my own server to receive this?
Yes — this destination expects your own endpoint (or a tool like a serverless function, a script, or another automation platform's webhook trigger) to receive the POST. If you don't have one yet, pick one of ZestyGlue's built-in destinations instead.
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.
