# Idempotency

> Idempotency prevents duplicate resource creation caused by retries or network interruptions. Include an idempotency key when performing write operations (**POST** or **PUT**).

```http theme={null}
Idempotency-Key: <unique_uuid>

```

<Note>
  Idempotency Guarantee: If a request with the same key is received multiple times, the API will return the original
  response instead of creating duplicate resources. Use UUID v4 for these keys.
