What is API Monitoring? Keeping the Steady Heartbeat of Healthy APIs

API Monitoring refers to an automated series of tests that run in the background. These tests are continuously checking to ensure your APIs are performing as expected once they are in production, based on the criteria and assertions you specify.


3 API Monitoring KPIs

Here are the 3 fundamental areas that API monitors perform a “health check” for:


Is the API available and responding? If so, great! If the API is unavailable, your customers could be severely impacted by this error in real time.



If the API does respond, how quickly does it respond? Is it responding quickly enough to support the use cases of your business?



Is the API returning the correct data, and is the data structured properly?


Constantly monitoring these 3 areas help to ensure that your APIs are healthy and in good condition to serve your customers accordingly as they utilize your application.


Why Do I Need to Monitor My APIs?

1. Ensure Customer Satisfaction

When your customers are faced with downtime and API errors, you’ll be faced with a rise in support tickets, complaints, high bounce rates and app abandonment. These problems can most certainly lead to long-term effects as well. Strive to deliver a customer experience that you would want to receive yourself!


2. Cover Your Testing Bases

While it is imperative to “shift left” and test early and often, it is equally as important to test and validate your API responses and data structures after production. API Monitoring typically occurs after an application has already been deployed, although it can be performed in staging or even development as well. By ensuring that you’re continuously testing even after deployment, you can discover and more readily fix any API issues before your customers notice.


3. Identify the Culprit

Without proper visibility into the traffic running through your apps and infrastructure, diagnosing and solving the problem means using up valuable time and resources. API monitoring surfaces issues directly from the internal and third-party APIs that power your apps and infrastructure, and gives you visibility into these problems so you can prevent, identify and solve them quickly.


I like to think of API monitors as built-in doctors who identify and diagnose problems, and notify you when you need to take action. API monitoring gives you peace of mind that your APIs are working quickly, efficiently and correctly, and that your customers are getting an excellent end-to-end experience.
