Access to the SDM API is provided through Google Cloud Platform (GCP). To enable the API and authorize a Google account with a supported Google Nest device, you'll need a GCP project.
You can use an existing GCP project or create a new one. If you don't have a project, or are not familiar with GCP, we recommend you go through the Quick Start Guide first. It guides you through all the steps necessary to get started with Device Access.
To learn more about creating projects and GCP in general, we recommend the following resources:
Enable the API
The API Library listed in GCP for Device Access is Smart Device Management API. Before you can use Device Access you must enable this API in your project.
Enable Smart Device Management API on the API Enablement page.
OAuth 2.0 Client ID
The SDM API uses Google OAuth for user authorization. In order to complete the authorization process, you need to generate OAuth credentials in the form of an OAuth 2.0 Client ID.
Get an OAuth 2.0 Client ID on the Credentials page.
The SDM API uses a sensitive scope, which means that any apps that use this scope during authorization will be "unverified" unless OAuth API Verification is completed. When using Device Access for personal use, OAuth API Verification is not required.
You may see a "This app isn't verified" screen during the authorization process,
which appears if the
sdm.service scope is not configured on your
OAuth consent screen in GCP. This screen can be
bypassed by clicking on the Advanced option.
See Unverified app screen for more information.
