Dialogflow FAQ Sample

The following sample uses Knowledge Connectors to create an agent surfaced on the Google Assistant and phone calls through Actions on Google and Dialogflow's Phone Gateway.

  • Knowledge connectors allow you to connect FAQ and knowledge-base-style articles to Dialogflow without creating any intents or manual configuration. Dialogflow parses the documents and determines if a user's query would be satisfied by information in the document, and if it is, the information from the document is relayed back to the user.

  • This sample is meant to be a starting point for developers looking to create an action that is also accessible by phone as well as developers looking to connect FAQ or knowledge base data to a Dialogflow agent.


To create this agent from our template:

Knowledge Connector

  1. From the left column, go to the Knowledge tab > Create Knowledge base.
    • Name the knowledge base Conference > Save.
  2. To create a knowledge document: Create the first one and add:
    • Conference FAQ for the Document Name,
    • text/csv for the Mime Type,
    • FAQ for the Knowledge type
  3. Under Data source select File on Cloud Storage and enter gs://cloud-next-csv/next-faq.csv > Create.
  4. On the same page, go to the Responses section > Add response > Set the default response to $Knowledge.Answer[1]. Have any other questions? > Save.
  5. Under Responses, next to the Default tab > add Google Assistant and Simple Response with the value $Knowledge.Answer[1]. Do you have any more questions about Cloud Next? > Save.
  6. Try it out! In the Dialogflow simulator, enter What time does the conference start and end?.
    • You will see a response directly from the CSV: "The first keynote starts at 9 AM on Tuesday and programming ends at 2:30 PM on Thursday. We highly recommend picking up your badge on Monday (anytime between 7 AM and 8 PM) or early on Tuesday to avoid lines."

Phone Gateway

  1. Go to the Integrations tab > Dialogflow Phone Gateway > Next > Create
  2. Call the phone number displayed and talk to your agent!
    • Note: Calling the gateway from a device using Project Fi, Google Voice, or Google Hangouts is not currently supported.

Google Assistant

  1. Go to the Integrations tab in the left column > Google Assistant > Test > Continue in order to open the Actions on Google console.
  2. In the Actions on Google simulator > Talk to my test app and press enter.
  3. Continue the conversation with your Dialogflow agent through the Google Assistant!
    • You can also speak with you agent on any Google Assistant enabled device logged into the same Google account like Google Home speakers, smart displays, and mobile phones.
