Hello. I am using APEX 23.2.
In my app, there's a form where potential users can create accounts for themselves. One of the values that should be entered is their phone numbers. But I need to be sure that phone number entered is actually the user's phone number. So, I need to send an OTP or some type of code to that phone number, so I can ensure the one who enterd the phone is the owner when they enter the code sent to them in another item, for example.
Should I seek an SMS gateway? Will I be able to store the code before it gets sent to the user to be able to compare it with what they enter? For example, the gateway generates code 4567. The code is sent to the user. The user is navigated to a page with an item to enter that code. That's where I should validate the code they enter with the code the gateway generated. I hope it's clear.
