⁠Get support

Bugs and questions related to the source code and Docker image can be reported at Github Issues⁠ in the ismarslomic/google-assistant-oauth⁠ repo.

⁠About

In order to access the Google Assistant Service⁠ you need to retrieve access and refresh tokens by using Google OAuth2 implementation, this is explained in Google Authorization and Authentication documentation⁠ .

This utility simplifies going through the OAuth2 flow and was created in the context of implementing embedded Google Assistant for broadcasting message to Google Assistant enabled speakers, see ismarslomic/google-assistant-broadcast⁠ .

⁠Setup

⁠Prerequisites

• docker - you need to have Docker installed on your machine, read Get Docker⁠ for more information.
• Google OAuth 2.0 Client ID - in order to authenticate yourself and get access to your Google Assistant.
  • Follow steps 1-5 in Configure an Actions Console project⁠
  • Make sure that you choose "Device registration" when creating new project in Actions Console
  • !Important! Download the OAuth Client file from GCP Console / API & Services / Credentials page (not from Google Actions Console), read solution on issue #7⁠. Make also sure that the Application type of the OAuth Client is Desktop
  • Rename the downloaded file from client_secret_****.apps.googleusercontent.com.json to client_secret.json

⁠Run docker container with docker run

Replace /home/pi/config with full path to the folder where your client_secret.json file is located.

When docker container is terminated and the OAuth2 flow finished, you will find tokens.json file produced in the same folder.

docker run --rm \
-p 3005:3005 \
-v /home/pi/config:/usr/src/config \
ismarslomic/google-assistant-oauth:latest

Click on the URL provided in the console output from the Docker container.
