Why API monitoring and alerting in Rest API? - Purpose & Use Cases

The Big Idea

What if your website breaks and you only find out hours later? API monitoring stops that nightmare.

The Scenario

Imagine you run a website that depends on many APIs to work. You check each API by opening your browser or running commands one by one every hour to see if they are working.

The Problem

This manual checking is slow and tiring. You might miss problems if you are busy or asleep. Also, it is easy to forget or make mistakes, causing your website to break without you knowing.

The Solution

API monitoring and alerting tools automatically check your APIs all the time. They tell you immediately if something goes wrong, so you can fix it fast before users notice.
