Idempotency

Borrador de traduccion automatica (Spanish) for "Idempotency": The property of an operation where performing it multiple times produces the same result as performing it once. Idempotent API endpoints are critical for safe retries — if a network error occurs, the client can re-send the request without fear of duplicating side effects like charges or database records.

“Ejemplo en borrador: Pass an idempotency key with payment requests so retries don't charge the customer twice.”
