Can you explain the difference between idempotent and safe APIs?
Sure! Idempotent APIs are those that can be called multiple times without changing the result beyond the initial application. Safe APIs, on the other hand, are designed to not change the state of the server, meaning they can be called without any side effects.
Can you give me an example of each?
Of course! A common example of an idempotent API is a DELETE request to remove a resource. Calling it multiple times will have the same effect as calling it once. A safe API example is a GET request, which retrieves data without modifying it.
Why is it important to understand these concepts?
Understanding these concepts helps developers design APIs that behave predictably, improving reliability and user experience.
What happens if a safe API is called multiple times?
If a safe API is called multiple times, it will not change the server's state, so the result will be the same each time, ensuring consistency.
