Actions on Google: Transactions Sample

This sample demonstrates Actions on Google features for use on Google Assistant including physical transactions -- using the Node.js client library and deployed on Cloud Functions for Firebase.

This sample shows everything you need to facilitate transactions, including:

• Check for transaction requirements
• Get the delivery address
• Confirm the transaction
• Examples of Google Pay and merchant-managed payment options
• Asynchronously update order status at any time (via order-update.js)

⚠️ This code sample was built using Dialogflow. We now recommend using Actions Builder or the Actions SDK to develop, test, and deploy Conversational Actions.

⚠️ Warning: Due to new regulatory requirements, transaction functionalities for Conversational Actions will not be available in the following countries after May 1, 2022: Denmark, France, Germany, Italy, the Netherlands, Norway, Spain, Sweden, Poland

   • 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}.cloudfunctions.net/dialogflowFirebaseFulfillment
   

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

• (Recommended) 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.

Order Updates (order-update.js)

Order Updates Configuration

1. In the Google Cloud Platform console, select your Project ID from the dropdown > Menu ☰ > APIs & Services > Library
