Why not call UptimeRobot's API directly from your own endpoint? You can — but then you own UptimeRobot'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

UptimeRobot — Down

Connection timeout
A real UptimeRobot event, shown as ZestyGlue formats it for Custom Webhook.
Setup — about two minutes
- Create the connector. In ZestyGlue, start a new UptimeRobot → Custom Webhook connector. You'll get a unique webhook URL right away.
- Point UptimeRobot at it. Go to My Settings → Add Alert Contact → Webhook, choose "Send as JSON", and paste in your ZestyGlue webhook URL.
- 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.
Tip: UptimeRobot sends the same alert type on both the way down and the way back up (Down, then Up) — seeing both in your channel means you always know when an incident actually resolved, not just when it started.

Questions
Does this work with UptimeRobot's free plan?
Yes — webhook alert contacts are available on UptimeRobot's free tier, not just paid plans.
Can I monitor multiple sites with one connector?
Yes — add the same ZestyGlue webhook URL as the alert contact on as many monitors as you like.
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 UptimeRobot's side — UptimeRobot 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.
