# What is Acilia ID

You will find references to an `aciliaId` in most API responses. This string is simply your 0x order encoded in a [JWT token](https://jwt.io/). Developers can store `aciliaID` in their own databases as if they were storing the entire 0x order, and can generate cancel and fill call-data by calling the API and passing in the appropriate `aciliaId`

Essentially,  `aciliaId` is a safe representation of a 0x order that will doesn't expire.

{% hint style="info" %}
You can always deserialize an`aciliaId` using JWT token libraries or the [JWT debugger UI](https://jwt.io/). Any `aciliaId` created from the Acilia NFT Swap API can be filled or cancelled without the need to the API.
