How to confirm or update user input in Dialogflow ES

One of the questions people ask is the following:

After user provides some input, I would like to either confirm the input or allow them to update it

Let us use the slot filling chatbot as an example.

Once the user provides all the input, we were only displaying the list to the user.

Add the following output contexts to the book.flight intent

await_confirmation with a lifespan of 1

session-vars with a lifespan of 50

And also ask the user to confirm the inputs in the response.

If user says Yes, we will end the chat.

If the user says no, we ask them what should be changed

Suppose the user wants to change the return date. We will add an intent to do that. Note that the parameter you use in the table should be the same as the one you used in the slot filling intent. This will make sure that the original value inside the session-vars context gets overwritten by the new value that the user has input.

In the same way, we can also allow the user to change the departure date

You can add more such intents depending on your use case by following the same pattern

Let us test the bot using the Dialogflow Messenger integration.

Here is the use case where the user confirms immediately.

The user changes the return date

User changes the departure date

"The magic key I needed as a non-programmer"

The custom payload generator was the magic key I needed (as a non-programmer) to build a good demo with rich responses in DialogFlow Messenger. I've only used it for 30 minutes and am thrilled. I've spent hours trying to figure out some of the intricacies of DialogFlow on my own. Over and over, I kept coming back to Aravind's tutorials available on-line. I trust the other functionalities I learn to use in the app will save me additional time and heartburn.

"Much clearer than the official documentation to be honest"

Thanks a lot for the advice (of buying and following your videos)! They helped a lot indeed. Everything is very clear when you explain, much clearer than the official documentation to be honest 🙂

"I will strongly recommend this course because even I can learn how to design chatbot (no programming background)"

I think Aravind really did a great job to introduce dialogflow to people like me, without programming background. He organizes his course in very clear manner since I have been a college professor for 20 years. It is very easy for me to recognize how great Aravind’s course is! Very use-friend and very easy to follow. He doesn’t have any strong accent when he gives the lectures. It is so easy for me to understand. Really appreciate it.

Yes, I will strongly recommend this course because even I can learn how to design chatbot (no programming background) after studying Avarind’s course, you definitely can!
