To create a Dialogflow Chatbot, you need to add an agent name. 

The name can be anything like your business name or the name you want to assign your WhatsApp Chatbot. 

Set up the default time period & hit Save.

Check out this tutorial to know how to create an agent.  

It's now time to use a pre-made Chatbot template to create your WhatsApp Chatbot. 

Go to your agent's profile & hit the Import & Export page. 

Pick any WhatsApp Chatbot Template from the many templates available & download the one which appeals the most to your business. 

E.g. If you run an Ecommerce Business, pick the Basic 1-9 FAQ Chatbot or Feedback Chatbot or Product Details Chatbot. 

Once you've downloaded the Chatbot Template, here's what you need to do👇‍

Now, extract the Zip file to a different location. 

Once you do it, upload the extracted file to your Dialogflow Chatbot, enter RESTORE & click the restore button to add the Chatbot Template successfully. 

Here, we've added the 1-9 Basic FAQ Chatbot Template to Dialogflow. 

Now, let's add the intent or purpose to the WhatsApp Chatbot. 

The intent here means the user's purpose for one conversation turn. For each agent, you define many intents, where your combined intents can handle a complete conversation. 

One intent performs one particular action or gives one particular piece of information. For a deep dive into intents, check out this tutorial. 

There are 2 things you need to fill to implement 1-9 Basic FAQ Chatbot:

1. Default Welcome Intent- This is the default welcome message triggered by the WhatsApp Chatbot upon receiving a particular message from the user. E.g. Hi, Hello. 

2. Queries- Queries refer to the general queries your user might have. You have to add the queries & their respective answers in this section. 

Let's first set the default intent 👇 

While setting default welcome intent, you need to think & fill in these two things:

1. Training Phrases- These are the user phrases that will trigger the Chatbot's Welcome intent. It can be anything you think your customer will message you. It can be a simple 'Hi', 'hello', 'just saying hi' etc.

2. Responses- This would be the message automated by the WhatsApp Chatbot, triggered upon receiving the training phrase. 

Your user can then pick from any of the options, depending on their query. 

In Queries, you need to set up the answers to the 1-9 FAQs one by one. 

For each query, you need to add a separate answer that will be automated when the user asks a query. 

E.g. If the user wants to know the answer to 'What is AiSensy?', they'll have to send '1' or ask 'What is AiSensy?" and the Chatbot will automate the answer to them. 

Queries are character sensitive. One word out of the place and the Chatbot won't recognize the user's intent. 

To set up queries, all you need to do is add the query number in the user expression (in this case '1') & add the answer to the query in 'Text Response'. 

Press 'Save' & go back to intents & do the same for other queries. 

No matter how intelligent your WhatsApp Chatbot is, there will be times when it won't understand the user expressions. 

It could be that the user sent a particular phrase in their native language that the Chatbot is unable to grasp. 

In such cases, the default fallback intent is matched when your agent doesn't recognize an end-user expression. 

The intent is further automatically configured with static responses such as, "I didn't get that. Can you say it again?"

To set up Fallback Intent, go to 'Default Fallback Intent" & add a response that will be automatically triggered when the Chatbot doesn't understand the user's expression.
