The sandbox issues real Umbrella API keys against a reserved sandbox organization; the same api.umbrella.com host and the same OAuth 2.0 client-credentials flow are used. test_values: published: false note: Cisco publishes no magic test domains, test identities or fixture values for the Umbrella API. Nothing is invented here. time_simulation: supported: false note: A reservation is required, so this is a gated sandbox rather than an anonymous playground; the reservation itself is free and self-serve through the DevNet Sandbox catalog.
