title: Server names description: Name your servers using the `x-fern-server-name` extension

The x-fern-server-name extension is used to name your servers.

openapi.yml

1 servers:
2   - url: https://api.example.com
3     x-fern-server-name: Production
4   - url: https://sandbox.example.com
5     x-fern-server-name: Sandbox

5 export type ExampleEnvironment = typeof ExampleEnvironment.Production;
