Requests come from the client specifically asking for a set of resources. This could be requesting the initial set of resources on a new connection, or from a new dependency. For example, a push of `Cluster X` referencing `Endpoint Y` may lead to a request for `Endpoint Y` if it is not already known to the client.

Jeder „Scope“ ist nur ein String (ohne Leerzeichen).

Diese werden normalerweise verwendet, um bestimmte Sicherheitsberechtigungen zu deklarieren, zum Beispiel:

* `users:read` oder `users:write` sind gängige Beispiele.
* `instagram_basic` wird von Facebook / Instagram verwendet.
* `https://www.googleapis.com/auth/drive` wird von Google verwendet.
