API Monitoring

Monitor API reliability by validating response status, payload expectations and latency across your critical endpoints. API monitoring goes beyond a simple reachability check: it confirms that an endpoint not only responds, but returns the data your applications and customers depend on.

What it checks

An API monitor calls an endpoint on a schedule and validates the response in more depth than a plain HTTP check:

• Availability and status - whether the endpoint is reachable and returns the status code you expect.
• Authenticated access - whether secured endpoints respond correctly when called with scoped credentials and custom headers.
• Payload correctness - whether the response body has the expected shape and contains the required fields, using assertions against the returned JSON.
• Performance trends - how endpoint latency changes over time, so you can detect gradual degradations early.
• Auth flows - behaviour of token creation, refresh and authorization rules on the endpoints that gate the rest of your API.

Configuration

API monitors are configured around the request you want to make and the expectations you want to assert:

• Endpoint URL - the address of the API endpoint to call.
• Headers and authentication - custom request headers and credentials, such as an API key or bearer token, needed to reach a secured endpoint.
• Expected status - the status code that counts as a healthy response.
• JSON assertions - checks against fields in the response body, such as confirming a field is present or matches an expected value.
• Check interval - how often the monitor runs.
