Can you explain what API routes mean in web application development?

API routes in web development are endpoints on the server that handle HTTP requests from clients. Each route corresponds to a specific URL and method (GET, POST, PUT, DELETE, etc.) and is responsible for executing a particular operation, such as retrieving data, creating a record, or deleting.

For example, in REST APIs, routes facilitate interaction between the frontend and backend, allowing clients to request or modify data.

Example of an API route:

GET /api/users/123

This route might return information about the user with ID 123.

In testing API routes, it is important to verify the correctness of responses, status codes, and error handling.
