In sofware and tech idempotency typically refers to the idea that you can perform an operation multiple times without triggering any side effects more than once.
Here's the main facts you need to know about idempotency:
- Idempotency is a property of operations or API requests that ensures repeating the operation multiple times produces the same result as executing it once.
- Safe methods are idempotent but not all idempotent methods are safe.
- HTTP methods like GET, HEAD, PUT, DELETE, OPTIONS, and TRACE are idempotent, while POST and PATCH are generally non-idempotent.
