Using Dialogflow with Firebase and the Vonage Messages Sandbox

This tutorial guides users in setting up a chatbot using Dialogflow, Firebase, and Vonage Messages API to interact with customers and handle incoming requests such as reservations, bank inquiries, FAQs, and initial support. The user needs to have a Vonage API account, create a Firebase application, set up the Dialogflow agent, download service account keys, build functions locally, and deploy them to Firebase. The chatbot can then be tested on Facebook Messenger using the Vonage Messages Sandbox Inbound webhook. The tutorial provides sample code for sending messages to the Vonage Messages Sandbox and forwarding user input to the Dialogflow agent to determine the intent of the message.
