The [fiskaly SIGN AT](https://developer.fiskaly.com/api/rksv/v1) is idempotent. [Idempotence](https://wikipedia.org/wiki/Idempotence) means you can send the same request several times safely. The result will be the same as if you have sent it only once.

For example, if you request to [sign a Receipt](https://developer.fiskaly.com/api/rksv/v1#operation/signReceipt) but don't receive a response, you can send the request again with the same request body. The receipt is guaranteed to be signed only once.
