API Monitoring

What is an API used for?

API stands for Application Programming Interface. An API is a piece of software that acts as an intermediary allowing two applications to communicate to each other. For example, every action we take on a mobile phone, like sending a message or looking for a flight using a comparison website, uses an API to access and deliver that information.

How do I monitor API health?

Your API health can be monitored through tools such as ITRS Synthetic Monitoring, which are designed to give you full visibility into the performance of your applications and the way they connect to each other. API monitoring gives your IT teams peace of mind, as most organisations depend on APIs to ensure business-critical applications are always up and running. 


Continuously test your API responses

Are you using programs like Postman, Fiddler or SoapUI to test your API? We love those tools, too, but manual testing will only get you so far. You need continuous automated testing to monitor changing circumstances, such as:

  • Failing resources
  • Network issues
  • Availability of the underlying database
  • Expired security credentials

Keep your APIs up and running

Multi-Step monitoring

Test your APIs from top to bottom by setting up multiple HTTP requests. Retrieve data from each request and use it to perform tasks in other steps.

Monitor for performance

Check the performance of every request, and set assertions for maximum response times. Spot trends in your performance dashboards.

Verify API functionality

Test redirects, authentication, perform CRUD, or any other API interaction. Monitor for result codes, and check if your API returns expected content.

Get alerts immediately

With tests as frequent as every minute, you will know the moment your API is in trouble with alerts and escalations.
