Type String

The id member is a string that represents the identity of the web application — the unique identifier for the web application. If the web application ID does not match an existing ID, the application will be treated as a unique identity even if it is from the same URL.

Note: The id member can be used to uniquely identify applications. The id member is processed like a start_url but can be out of scope because it does not point to a resource that can be navigated to.
