Configure a Google Cloud Platform project

AI-generated Key Takeaways

• The Google Assistant SDK is intended for non-commercial and experimental purposes only, prohibiting commercial device integration.

• A Google Cloud Platform project is necessary for accessing the Google Assistant API, enabling quota tracking and metric analysis.

• Enabling the Google Assistant API requires creating or selecting a project within the Google Cloud Platform Console and enabling the API for the project.

• An OAuth Client ID is needed and can be generated by creating a client ID, potentially setting a product name, providing a client ID name, and downloading the client secret JSON file.

• The client secret JSON file, essential for authorization, must be placed on the device, specifically in /home/pi for Raspberry Pi, potentially requiring secure copy transfer from a local machine.

Warning: You can't launch commercial devices that integrate with the Google Assistant SDK. It's available for experimental and non-commercial uses only.

A Google Cloud Platform project gives your project access to the Google Assistant API. The project tracks quota usage and gives you valuable metrics for the requests made from your hardware.

To enable access to the Google Assistant API, do the following:

1. In the Cloud Platform Console, go to the Projects page. Select an existing project or create a new project.

   Go to the Projects Page

2. Enable the Google Assistant API on the project you selected (see the Terms of Service).

   Enable the API

   Click Enable.

3. Create an OAuth Client ID with the following steps:

   1. Create the client ID.
      Create an OAuth Client ID

   2. You may need to set a product name for the product consent screen. On the OAuth consent screen tab, give the product a name and click Save.

   3. Click Other and give the client ID a name.

   4. Click Create. A dialog box appears that shows you a client ID and secret. (No need to remember or save this, just close the dialog.)

   5. Click ⬇ (at the far right of screen) for the client ID to download the client secret JSON file (client_secret_<client-id>.json).

4. The client_secret_<client-id>.json file must be located on the device to authorize the Google Assistant SDK sample to make Google Assistant queries. Do not rename this file.

   For the Raspberry Pi only:

   Make sure this file is located in /home/pi. If you want to upload the file to the device, do the following:

   1. Open a new terminal window. Run the following command in this new terminal:

      Note: Do not run the following command in an SSH session connected to the device. This command transfers the JSON file from a directory on your development machine to the device. An SSH session cannot access your local directories.

      scp ~/Downloads/client_secret_client-id.json pi@raspberry-pi-ip-address:/home/pi/

      password: password-for-device

   2. Close this terminal window.
