I use Amelia bookings plugin so customers can book appointments online.
I want that during the booking process when a customer inputs his phone number he needs to verify it. It will send a verification code to his whatsapp using the whatsapp business api.
I think this is where I would need a developer but I’m not sure what the developer needs knowledge in?
I asked chatgpt and got this response. Would this be the correct way of going on about it?

“Here’s how you can integrate the WhatsApp Business API to authenticate users during the appointment booking process:
**Step 1: Modify the Booking Form**
You need to modify the booking form to add a button that triggers the WhatsApp authentication. This button should be disabled until a valid phone number is entered. You may need to customize the plugin’s PHP and JavaScript files to do this.
**Step 2: Implement the WhatsApp Business API for Authentication**
When the user clicks the authentication button, perform the following steps:
​
1. Retrieve the phone number that the user inputted.
2. Generate an authentication code and temporarily store it on the server.
3. Use the WhatsApp Business API to send this code to the user’s phone number.
**Step 3: Add an Input Field for the Authentication Code**
After the code is sent, provide an additional input field for the user to enter the received code. This field can be displayed dynamically using JavaScript after the user requests the code.
​
1. When the user enters the code and presses a “Verify” button, use AJAX to compare the entered code with the stored one on the server side.
2. If the codes match, mark the verification as successful. You can visually indicate this on the form, for example, by changing the color of the verification button.
3. If the codes don’t match, let the user know and give them an opportunity to retry.
**Step 4: Complete the Booking**
Only allow the user to complete the booking if the phone number verification is successful.
