Monitor APIs in Production

Catch Breaking Changes Before Your Customers Do

Send real HTTP requests with auth, validate response codes, headers, and body content — so your APIs keep working after every deploy.

 

A 200 OK Response Doesn't Mean Your API Works

An authenticated endpoint can return 200 while returning completely wrong data. A login endpoint can succeed and still be missing tokens. Real API monitoring doesn't just check availability — it validates responses. Updown Monitor does both.

 

What You Can Monitor

REST & GraphQL

GET, POST, PUT, PATCH, HEAD — all supported with custom request bodies.

Authenticated Endpoints

Bearer tokens, API keys, or HTTP basic auth — credentials stored securely.

Response Validation

Check for specific status codes, required response body content, and expected headers.

Multi-Region Checks

Detect latency or outages affecting specific customer regions.

Response Time Alerts

Alert when response times exceed your SLA thresholds.

SSL & Certificate Tracking

Automatic SSL validation. Alerts on expiry, mismatches, and trust issues.

 

Frequently Asked Questions

Add your API key or token as a custom request header, or use HTTP basic auth with username and password.

Yes. Configure POST/PUT/PATCH with custom request bodies (JSON, form data, or plain text) and validate the response.

Set an expected substring in the response body or expected response headers. When they change, you get alerted.

Yes. GraphQL is just POST with a JSON body — configure that in our monitor settings and validate the response.

Yes. Monitor your staging and production APIs separately. Catch regressions before they reach end users.
