Understanding Idempotency in Software Engineering

Question

Idempotency

In software engineering, an operation is considered idempotent if applying it multiple times has the same result as applying it once.

For example, an API endpoint PUT /user/1 that updates a user's name is idempotent because making the same request twice leaves the system in the same state. A POST /user endpoint that creates a new user each time is not idempotent.
