Keywords

💡Dialogflow

Dialogflow is a natural language understanding platform that allows developers to build conversational agents or chatbots. In the video, Priyanka Vergadia demonstrates how to integrate Dialogflow with Twilio's messaging service to enable chatbot functionality. Dialogflow processes user input in natural language and allows bots to understand and respond appropriately.

💡Twilio

Twilio is a cloud communication platform that provides messaging services like SMS, voice, and video. In the video, Twilio’s programmable SMS service is integrated with Dialogflow, allowing users to interact with the chatbot via text messages. This enables users to have the same experience through SMS as they would on a web platform.

💡Appointment Scheduler

The appointment scheduler is the example chatbot used in the video. It helps users schedule appointments through text messaging. The video focuses on integrating this chatbot with Twilio to allow users to book appointments via SMS, providing the same functionality across different communication platforms.

💡Integration

Integration in this context refers to connecting Dialogflow with Twilio’s messaging service. This process involves setting up communication between the two platforms so that the chatbot can receive and respond to messages sent via SMS. The video walks through the integration process step by step.

💡Programmable SMS

Twilio’s Programmable SMS is a service that enables developers to send and receive text messages using the Twilio API. In the video, this service is used to facilitate two-way interaction between the chatbot and users via SMS, allowing for seamless communication.

💡Natural Language Understanding

Natural Language Understanding (NLU) is the capability of a machine to understand and process human language. Dialogflow, used in the video, is an NLU tool that helps the chatbot comprehend and respond to user inputs, such as scheduling an appointment through a simple text command.

💡Request URL

A Request URL is a web address used to send data between two systems. In this video, the Request URL generated by Dialogflow is pasted into Twilio’s settings to enable communication between the chatbot and Twilio's SMS service. It is a crucial part of the integration process.

💡Auth Token

An Auth Token is a unique identifier used for authentication. In the integration process described in the video, the Auth Token from Twilio is used to securely connect Dialogflow with Twilio’s messaging service, ensuring only authorized systems can interact with the SMS service.

💡Messaging Service

The messaging service in Twilio allows developers to send and receive SMS messages. In the video, the chatbot is integrated with this service, which means that users can now interact with the appointment scheduler via text messaging, providing a new channel for communication.

💡Inbound Settings

Inbound Settings determine how Twilio handles incoming messages. In the video, enabling inbound settings allows the system to receive messages from users and send them to the Dialogflow chatbot. This setting is essential for the two-way communication between the user and the bot.

PRIYANKA VERGADIA: Welcome to Deconstructing Chatbots.

I am Priyanka Vergadia, and in this episode,

we will integrate Dialogflow with Twilio's messaging

service.

[MUSIC PLAYING]

One of my friends uses Twilio messaging service

and requested that I walk him through setting up

Twilio bots with natural language understanding

based on Dialogflow.

So here we go.

Again, we are going to work with the same appointment scheduler

chatbot and integrate it with Twilio's messaging service

so that our users who choose to text us

can get the same experience as the ones who are using us

on web and Google Home.

We are in our agent.

Let's click Integration.

This time we are going to click on Twilio's text messaging

service.

The pop-up has some instructions-- click on Start,

copy the request URL, and put it in the Twilio's

programmable SMS.

There are more instructions; if you click on the link,

it takes you to the detailed screenshots

and how to set it up.

But for now, let's just do it ourselves.

The first thing you will need is a Twilio account.

If you don't have one, create it and then log in.

From the dashboard, click on All the Products

and navigate to Programmable SMS.

Once you are on the Programmable SMS dashboard, click on SMS.

I already have an appointment scheduled a messaging service

set up here, but you can just create one for yourself,

provide it a name, and in the use case,

select Chatbot Interactive 2-Way.

Let's click on the messaging service you

created to assign a phone number.

Use the Add button to buy a new phone number

or just use an existing number if you have one.

Click through the US selections and you

should have a number assigned.

Now we click on the configuration

to integrate Dialogflow.

Enable inbound settings.

In the request URL, copy and paste

the URL that was generated by Dialogflow in the Integration

section and save it.

Now copy the service ID, phone number, and the auth token

from Twilio dashboard and paste them in the Dialogflow

Integration Console again.

Once you're done, click on Save and start.

Yay!

Our bot started successfully.

Now it's time to test your bot via text messages.

So we will use the number we assigned

to our messaging service and run through that example again.

Hi.

I would like to set an appointment for 3:00

PM tomorrow.

Driver's license.

Great, we received a confirmation.

All right.

So today we integrated our appointment scheduler chatbot

with Twilio messaging service, enabling our users

to set an appointment via text.

We managed to provide the exact same experience

to our users using our bot from the website or via text.

Well, that's a win.

That's it for today.

Join me in the next episode for deconstructing chatbots

where we will learn more about fulfillments.
