## Overview
Use the UUID generator transform to create a universal unique ID (UUID) in the form of a 36-character string.
:::note Other Considerations
There is no uniqueness checking in this transform - the underlying code is written to provide a 1 in 68,719,476,736 chance of creating a string that actually collides with another string within the tenant, so the generated UUID's uniqueness is very likely, but it is not guaranteed.
:::
## Transform structure
The UUID generator transform only requires the transform's `type` and `name` attributes:
```json
{
"type": "uuid",
"name": "UUID Generator Transform"
}
```
## Attributes
- **Required Attributes**
- **type** - This must always be set to `uuid`.
- **name** - This is a required attribute for all transforms. It represents the name of the transform as it will appear in the UI's dropdown menus.
- **Optional Attributes**
- **requiresPeriodicRefresh** - This `true` or `false` value indicates whether the transform logic should be reevaluated every evening as part of the identity refresh process.
## Examples
This transform produces a UUID such as "f7493c55-f3fc-491a-b352-4664d71f885b".
**Transform request body**:
```json
{
"type": "uuid",
"name": "UUID Generator Transform"
}
```
