Now you have a new Dialogflow agent to build your theatre booking chatbot.

2. Creating Intents

Intents are the building blocks of a chatbot in Dialogflow. They represent different actions or tasks the chatbot can perform based on user input. For our theatre booking chatbot, we'll create four primary intents:

a. Welcome Intent

This intent greets users when they first interact with the chatbot.

2.1. In the Dialogflow Console, select "Intents" in the left sidebar.

2.2. Click "Create Intent".

2.3. Name the intent "Welcome".

2.4. In the "Events" section, add the "WELCOME" event.

2.5. In the "Responses" section, add a few greeting messages, such as:

• "Hello! Welcome to Theatre Booking. How can I help you today?"
• "Hi! I'm your Theatre Booking assistant. What can I do for you?"
• 2.6. Click "Save".

b. Show Listing Intent

This intent provides users with a list of available shows at the theatre.

2.7. Click "Create Intent".

2.8. Name the intent "ShowListing".

2.9. In the "Training Phrases" section, add sample user inputs, such as:

• "What shows are available?"
• "List the upcoming shows."
• "Tell me about the shows playing at the theatre."

2.10. In the "Responses" section, add a response listing the available shows, such as:

• "Currently, we have the following shows available: Show A, Show B, and Show C. Which one would you like to book?"

2.11. Click "Save".

c. Booking Intent

This intent handles the process of booking tickets for a specific show.

2.12. Click "Create Intent".

2.13. Name the intent "Booking".

2.14. In the "Training Phrases" section, add sample user inputs, such as:

• "I want to book tickets for Show A."
• "Book 2 tickets for Show B."

2.15. In the "Actions and Parameters" section, add two parameters: "show" (with entity type "@sys.any") and "ticket_count" (with entity type "@sys.number").

2.16. In the "Responses" section, add a response confirming the booking, such as:

• "Great! I've booked {ticket_count} tickets for {show} for you. Enjoy the show!"

2.17. Click "Save".

d. Theatre Information Intent

• ^This intent provides users with general information about the theatre, such as its location, contact details, and seating capacity.

2.18. Click "Create Intent".

2.19. Name the intent "TheatreInformation".

2.20. In the "Training Phrases" section, add sample user inputs, such as:

• "Where is the theatre located?"
• "What's the seating capacity?"
• "How can I contact the theatre?"

2.21. In the "Responses" section, add a response containing the theatre information, such as:

• "Our theatre is located at 123 Theatre Street. The seating capacity is 500. You can contact us at (555) 123-4567 or email us at info@theatre.com."

2.22. Click "Save".

Fulfillment and Webhooks

For more complex tasks, such as querying a database for show availability or processing payment information, you'll need to use Dialogflow's fulfillment feature and webhooks. This allows your chatbot to communicate with your server-side code to perform actions that can't be handled within Dialogflow alone. To learn more about fulfillment and webhooks, refer to the official Dialogflow documentation.

Testing the Chatbot

Once you've created the necessary intents, it's time to test your chatbot. You can use the Dialogflow Console's built-in simulator to interact with your chatbot and ensure it's working correctly.

4.1. In the Dialogflow Console, locate the simulator on the right side of the screen.

4.2. Type sample user inputs and verify that your chatbot responds correctly.

4.3. Make any necessary adjustments to your intents and responses to improve the chatbot's performance.

Integrating with Channels

Now that your chatbot is working correctly, you can integrate it with various communication channels, such as websites, mobile apps, and messaging platforms like Facebook Messenger or Slack. Dialogflow provides several pre-built integrations to make this process easier. To learn more about integrating your chatbot with different channels, refer to the official Dialogflow documentation.

Conclusion

In this tutorial, we showed you how to create a basic theatre booking chatbot using Google Dialogflow. By following these steps and using real code examples, you can build a functional chatbot to enhance user experience and streamline the booking process.
