Dictionary term
Idempotency
Also called idempotent request
Automation PlatformsAdvanced
A property where making the same request multiple times produces the same result as making it once, preventing duplicate side effects.
In plain English
Idempotency means sending the same request twice has the same effect as sending it once, so a retry can't create duplicates or double charges.
Analogy
Like pressing a floor button in an elevator twice: the second press changes nothing.
Why it matters
Idempotency keys stop retries and duplicate webhooks from creating double contacts or charging a customer twice.
In practice
Passing the same Idempotency-Key header so a retried payment isn't charged twice.
