The bot is a smart chatbot. Hence it can handle different variations of the same question.
For eg. in our Book Room example, we have the user say "I want to book a room". In this case, the bot should also be able to direct the user to this flow if he says something along the lines of "I would like to book a room", "I want to book a room for my stay" etc.
User: I want to book a room.
Bot: How many rooms would you like to book?
User: 2 rooms
Bot: What type of room would you want to book?
- Button1 - Simple
- Button 2 - Deluxe
User: (Clicks on Button 1)
Bot: You have chosen to book 2 simple rooms
User: I want to have my room cleaned
Bot: When should I arrange for a cleaning?
User: Could you send someone right now?
Bot: Sure, I will send someone to your room right away.
User: I want to have my room cleaned
Bot: When should I arrange for a cleaning?
User: Could you send someone after 2 hours?
Bot: Sure, I have scheduled a cleaning for 5 pm today.
The bot adapts according to the user input. For eg., if the user says "I want to book a room for 2 people", the bot does not ask "How many rooms would you like to book?".
User: What are your check-in timings?

User: What are your check-out timings?
Bot: Check-out time is 11 AM. Please contact the reception for late checkout requests.
User: How do I cancel a reservation?
Bot: To cancel a reservation, select the “Reservations” link from the homepage.
Bot: On the Reservations page, under the heading ‘View, Change or Cancel a Reservation,’ enter your confirmation number, and either the last name on the reservation or the last four digits of the credit card used to make the reservation.
User: What is your cancellation policy?
Bot: The booking deposit is refundable if the cancellation occurs at least 15 days before arrival. For cancellations made after this limit, a penalty will be imposed based on the cancellation policy.
User: Does the hotel have a restaurant?
Bot: Yes, the hotel has a restaurant called the Zephyr Bar. With our menu we strive to reflect the historic art and the spirit of our neighborhood by offering a glimpse into what makes our area unique.

User: What are the timings of your restaurant?

In natural conversations, users do not always follow pre-defined paths. In an attempt to add some flexibility for that, I have added some functionality to handle questions asked in the middle of a pre-defined flow.
The flows are divided into two parts - multi-step pre-defined flows, and FAQs.
For a small example -
User: I want to book a room.
