Need help learning how to create apps that work with the WhatsApp cloud and WhatsApp business

hello i have a project and i need some help.

the object of the project is to create an app that works with the WhatsApp cloud and businesses server so that a “bot” will send the user (via the WhatsApp) messages regarding home options.

for example, when installing the app you created a scene that sends you a WhatsApp message when you get close to your home:" i see that you are close to your home, would you like to turn the alarm off ? ", then the user can text back in WhatsApp “yes” and this will make the alarm turn off.

my problem i have no knowledge in LUA, whatapp cloud services or whatapp business, so i need help in those area, specifically get tutorials that will help me learn the tools i need
