**Scalar**
## UUID

<p>
    The `ID` scalar type represents a unique identifier. 
</p>
<p>
    The `ID` type appears in a `JSON` response as a `String`; however, it is not 
    intended to be human-readable. The `ID` is mathematically universally unique across all types and Vendors
    and can be used as such.
