Idempotent
An operation that can be performed multiple times without changing the result.
The comparisoni
“Setting a value to 5 is idempotent; no matter how many times you do it, it stays 5.”
The ruleii
¶
IDEMPOTENT = doing it once is the same as doing it ten times.
Mathematical term. In APIs, a POST is usually NOT idempotent because it creates a new resource every time.
Memory aidiii
Remember it like this
Idem (Same) + Potent (Power).
