Conditions and Assertions

Setting conditionsand assertions based on the results of API calls

Key Concepts


Setting Assertions/Conditions in an API call

The main way to handle assertions/conditions is via the Conditions tab on the Edit API Call page. You can also set timing-based conditions in the SLA Management option.

APImetrics reviews results returned by an API call in a specific sequence.

  • HTTP Status Code
  • Response Body Size
  • Header Content
  • Body Content
  • API Call Timing

Default Settings

By default, a call that returns a HTTP 2xx status code is considered a pass and one that returns a 5xx code is considered a fail. However, from the Conditions tab in the API editor you can change the defaults (for instance, to consider HTTP 4xx status codes as fails or, for negative testing, HTTP 2xx status as fails) and parse results or set specific timing-based rules.


Default pass HTTP 2xx status code

By default, a pass is any code returned with a 2xx result.


Default failure HTTP 5xx status code

By default, any 5xx code is deemed a failure


Default warning HTTP 4xx status code

Typically, a warning is due to an authentication error with the API call and warnings are not usually handled in the statistics that focus on pass and fail.

Result Events

When a condition is met, there are 4 possible outcomes

  • ignore the result (no change)
  • treat the result as a pass,
  • treat the result as a failure
  • treat the result as a warning.

Alerts can then be keyed to work off the triggered event.

Different handling events and triggers can be set for a True or False result.
