API monitoring · Fajita

Outcome

An API monitor sends a configured request and asserts on the status code, timing, headers, and JSON body.

API monitors support GET, HEAD, and POST. Set a request body for POST.

Add request headers, including an authorization header. Store the token as a secret so it is encrypted and masked.

Example request headers (placeholder token)

Authorization: Bearer YOUR_API_TOKEN
Accept: application/json

Assertion	Use
Status code	Require an exact code or accepted set
Response time	Fail or degrade past a threshold in milliseconds
Header equals	Require a response header value
JSON path	Check a value inside the JSON body

For JSON checks, see JSON path assertions.

A request that does not complete within the monitor's timeout is a failure. The default timeout is 10 seconds.
