Making chatbots reply smarter with context using Dialogflow Fulfillment

Let's take a closer look at the code. Let the agent (a webhook client) use the intent map to handle incoming messages. Remember to create those intents in Dialogflow and turn on the webhook fulfilment. Next, for each intent that acts on the customer's query (such as the ticket price inquiry in this case), the chatbot will reply based on the number of participants (children, adults and seniors), the site they wish to visit, and the citizenship. So how should the bot exactly reply?
