    "description": "To make a request idempotent, add the header `X-Payout-Idempotency` to the request and pass an idempotency key against it.\n\nAn idempotency key is a unique value generated by you. Our servers use this key to recognize subsequent retries of the same request.\n\nThe idempotency key (4-36 characters) can only contain alphabets, numbers, hyphens, underscores and space. For example, `53cda91c-8f81-4e77-bbb9-7388f4ac6bf4`. We recommend you generate the key using a version 4 (random) UUID generator.\n\nKnow more about [Idempotent Requests](https://razorpay.com/docs/api/razorpayx/idempotency/)."
