Let's Continue where we left off in our previous post. We will start configuring DialogFlow for processing our Intents, Entities and webhook.

3. Configuring and Working with DialogFlow


Steps to Create a New Dialogflow Agent:

  1. A Gmail account to access Dialogflow

  • Each Intents will automatically resolved to Parameter value and its corresponding resolved value.
  • In Response Section add: "If you don't see any articles, Please visit Our Website for Latest Updates".

  •  Enable Webhook call for this Intent.
8. Click on Fulfillment in Left Most Panel, Enable Webhook and enter the URL as generated in ngrok for ex:

10. 10. Click on Settings Icon beside Agent Name in Left Most Panel. Check on V1 API and get      Client Access token to be Used later.

    One Can Use V2 API as well and has to modify the Response Format in Controller of Module.

     Client Access Token: *************************

4. Basic Module in Drupal8 to Communicate with DialogFlow

One can get the Drupal Module to setup Voice and Text Based Chat Bot that interacts with User at https://www.drupal.org/project/drupal_chatbot and can also get the code repository at Git Hub: https://github.com/samhaldia/drupal_chatbot.

 We need to configure our NLP as Dialogflow properly to meet the Module requirements as mentioned above and in my former post. Once we are done we can proceed with module installation and follow module configuration steps to enable it in our website.


5. Future Scope

No doubt, Chat Bots are another benchmark in User engagement. We can extend it further with complex functionalities to reinforce Business insights. It can have a wide domain of service some of which are:

1. Newsletter Subscribing
2. More Complex and streamlined Search either Voice or Text based
3. Content Recommendations
3. Collecting User interests, Queries, Properties, Feedback to provide a enhanced analysis reports to gain potential business insights
4. Helps to make contents User-Centric and streamlining services regularly based on user hits

By default 80 is the Server port) On execution of the above command, Localhost goes live and points to URLS mentioned in the image below.
