Webhook Boilerplate

Option 2: Dialogflow Console and Firebase CLI


  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 become your Project ID) > Create project > under More options > Conversational
  2. From the top navigation 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. From the left menu > select Intents > Default Welcome Intent, scroll down to the end of the page and under Fulfillment > Enable Webhook > Save.
    • This will allow you to have the welcome intent be a basic webhook intent to test.

Firebase Deployment

  1. On your local machine, 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. 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 on which the Assistant is signed into the same account used to create this project. Just say or type, “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.
