Access WhatsApp messages from the day using API

I am building an application using the WhatsApp Business Cloud API. Essentially I want to know if it's possible to build an application that collects all the messages from the day and downloads it. Specifically the media attached to it using the API. As far as I know you can use webhooks to get incoming messages. But in order to do this the application has to be run forever, and my cousin has a problem with this as it could cause problems to run an application forever vs just run it once a day. I'm able to send messages using the API and a python wrapper but that's much more simple than what I'm trying to do. Aditionally, there is an option of using selenium but that's not really an automated solution to what we're trying to do because everytime selenium executes the browser we'd need to log in using the QR code. If anyone has any idea if this is possible (or not possible) I'd be very appreciative!

//some code that isn't working yet

I'm new to all of this stuff so I don't really know how to set up a webhook either but my cousin who's business I'm building this app for doesn't ideally want to use a webhook.
