Integration of Salesforce With Dialogflow to Build Action For Google Home Assistant

Prerequisites :-
1.Google dialogflow account
2.npm
3.ngrok.exe
This tutorial shows you how to do Salesforce Integration with dialogflow to build a simple Dialog flow agent, walking you through the most important features of Dialog flow. You’ll learn how to:

• Create a Dialogflow account and your first Dialogflow agent, which lets you define a natural language understanding model.
• Extract parameters with entities, which let you define how data is extracted from user utterances. Entities let you categorize important parts of user utterances. This lets you extract data that matches a category instead of a specific utterance, giving you more flexibility.
• Manage states with contexts, which lets you persist conversation state across turns of a conversation.
• Integrate with the Google Assistant, which lets you deploy your Dialogflow agent as actions that users can invoke through the Assistant

Create your Dialogflow account
Now that you’re signed into your Google account, you can sign into Dialogflow by following these steps:
1. Click the Google login button.
