WatchMethods, headers & body
GET, POST, PUT, PATCH, DELETE or HEAD with custom headers and request body — test the endpoints your app actually calls.
API monitoring
Know your API is up — and correct
A 200 response is not enough if the body is wrong. WatchControl checks status codes, response time and the actual JSON your API returns.
Authentication
Basic and Bearer-token auth so you can monitor protected endpoints safely.
JSON & status assertions
Assert on a JSON path value and an expected status code — catch a degraded API that still answers.
Response-time limits
Flag an endpoint as down when it gets too slow, with full latency history for your SLA.
Multi-channel alerts
Email and webhook on every plan, plus SMS, with re-notify so nothing slips through.
Status pages & SLA
Publish API status and pull monthly SLA reports for stakeholders.
