In reply to your first question, you are right: google.appengine.api.app_identity.app_identity.get_default_version_hostname() gets the standard host name of the default version of the app. For example, if your application_id is my-app, then the result might be my-app.appspot.com. You may check this on the "google.appengine.api.app_identity.app_identity module" page <https://cloud.google.com/appengine/docs/standard/python/refdocs/google.appengine.api.app_identity.app_identity#top_of_page> .
In what concerns question 2), there does not seem to be a compelling need to programmatically obtain the custom name instead, as the standard host name and the custom one point to the same site, and can be used interchangeably. Mapping between custom ID has been performed by project owners, and the information should be readily available, even if not by means of an API call from your code. In other words, you are supposed to know your custom domain URL already. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
