Create guest embed token

Exchanges a public Click-to-Call token for a short-lived guest [Subscriber](/docs/platform/subscribers) token consumed by the Click-to-Call embed client. Use it only for a public embed flow that must place a call without exposing project credentials or requiring a full subscriber account. Use [Create Subscriber guest token](/docs/apis/rest/subscribers/tokens/create-subscriber-guest-token) when your server chooses the guest's allowed resource addresses, or [Create Subscriber token](/docs/apis/rest/subscribers/tokens/create-subscriber-token) for a known subscriber. #### Permissions The API token used to authenticate must have the following scope(s) enabled to make a successful request: _Voice_, _Messaging_, _Fax_, or _Video_.
