Actions on Google: Facts about Google

This sample demonstrates Actions on Google features for use on Google Assistant including custom entities, contexts, deep links, and rich responses -- using the Node.js client library and deployed on Cloud Functions for Firebase.

Setup Instructions


  1. Node.js and NPM
    • We recommend installing using NVM
  2. Install the Firebase CLI
    • We recommend using version 6.5.0, npm install -g firebase-tools@6.5.0
    • Run firebase login with your Google account


Actions Console

  1. From the Actions on Google Console, New project (this will be your Project ID) > Create project > under More options > Conversational
  2. From the top menu under Develop > Actions (left nav) > Add your first action > BUILD (this will bring you to the Dialogflow console) > Select language and time zone > CREATE.
  3. In the Dialogflow console, go to Settings > Export and Import > Restore from zip using the in this sample's directory.

Firebase Deployment

  1. In the functions directory, run npm install
  2. Run firebase deploy --project {PROJECT_ID} to deploy the function
    • To find your Project ID: In Dialogflow console under Settings > General tab > Project ID.

Dialogflow Console

  1. Return to the Dialogflow Console > select Fulfillment > Enable Webhook > Set URL to the Function URL that was returned after the deploy command > SAVE.
    Function URL (dialogflowFirebaseFulfillment): https://${REGION}-${PROJECT_ID}
  2. Add Deep Links:
    • Select Integrations from the left navigation menu > Google Assistant > Integration Settings > Implicit invocation > add choose_cats & choose_fact intents.
  3. From the left navigation menu, click Integrations > Integration Settings under Google Assistant > Enable Auto-preview changes > Test to open the Actions on Google simulator then say or type Talk to my test app.

Running this Sample

  • You can test your Action on any Google Assistant-enabled device. Make sure the Assistant is signed into the same account used to create the Actions project, and just say “OK Google, talk to my test app”.
  • You can also use the Actions on Google Console simulator to test most features and preview on-device behavior.

Automated Testing

Unit and integration tests are located in the functions/test/. In each of the JavaScript files, change projectId and pathToServiceAccount to your GCP project id and the path to the JSON file for your service account - please follow the following instructions on how to create a service account.

  1. npm install from the functions/ directory
  2. npm test


  1. One of the configuration variables you'll need to set in the code is fulfillUrl, which is the url of the fulfillment. Ideally, this should be a locally run cloud function. We recommend using firebase serve.
  2. To use Dialogflow API, you will need to have service account that has the "Dialogflow API client" role. You can set this in the GCP IAM page (see
