With WhatsApp flows, you can create mini apps inside WhatsApp and I will show you how easy is to create them with Kapso.
00:07
So we will create a WhatsApp flow that allows my customers to schedule appointments using the Cal.com API.
00:14
So here we have a default WhatsApp flow.
00:18
and a WhatsApp flow is made up of two main parts.
00:22
One is the JSON that defines each screen, and the second part is the code, the function that makes this WhatsApp flow dynamic.
00:32
So now, instead of learning how to create WhatsApp, flows from scratch, I am just gonna ask the Kapso agent to build it for me.
00:42
So I have a prepared prompt here with the basic Instructions and the Cal.com API documentation.
00:49
So let's go.
00:52
Kapso agent starts thinking and planning and, it will start building the WhatsApp flow.
00:59
alright, so the Kapso agent built the first version.
01:03
We'll see if it works.
01:07
So we will choose tomorrow.
01:11
So great.
01:11
It fetched the available slots.
01:15
I'm just going to select one.
01:20
All right.
01:23
And here is my confirmation screen.
01:26
I will click confirm booking.
01:30
All right, let's see if it worked.
01:34
So I just received an email confirming that the event was scheduled.
01:38
So.
01:38
Great.
01:39
It's working.
01:40
So that's how you create mini apps inside WhatsApp using Kapso.
