Use this when a web or mobile client needs to start a call without holding the workspace API key. The API key stays on your server. The client uses the returned token.

### Headers

  Workspace identifier for the API.
</ParamField>

### Response

The response includes an SDK token that expires 24 hours after it is minted.
