Define Idempotency in Stripe API terms.

Define Idempotency in Stripe API terms.

• A. Operation can only be performed once.
• B. Same operation can be applied multiple times without changing result after first success; GET/DELETE are idempotent; POST uses idempotency key; expires after 24 hours.
• C. It guarantees immediate success every time.
• D. It is used to encrypt payloads.

Answer: (B)

Idempotency in Stripe means that repeating the same API request will not change the result after it has succeeded once. For operations like retrieving a resource or deleting it, repeating the request is harmless and yields the same outcome each time. For actions that create or modify resources, Stripe uses an idempotency key: you attach a unique key to the request, and if Stripe sees the same key again with the same request, it will return the original response instead of performing the operation twice. That key is valid for about 24 hours, so retries within that window won’t create duplicates. In short, idempotency is about safely retrying requests without causing duplicates; it’s not a guarantee of immediate success, nor is it about encryption.
