What Is UUID Sample ID?

A sample UUID in documentation matches the real format, so developers parse and validate it correctly the first time.
It also survives schema checks in generated SDKs that expect a UUID type.

How to generate

Use a fixed, clearly-example UUID in prose.
Mark it as an example, not a real resource.
Keep the same value across the doc for consistency.

Use Cases

API reference pages.
SDK readmes.
Postman collections.

Code Examples

Example

{
  "id": "9f1c2d3e-4b5a-6c7d-8e9f-0a1b2c3d4e5f",
  "name": "example"
}

Frequently Asked Questions

Use a random or fixed sample UUID?

Fixed, so all examples in the doc agree and readers can match them.

Mark it as fake?

A note helps, but the format itself signals it is an example.
