Synchronise Prestashop and Laravel database

Hey guys,

So I've been working on this project for a while now. It's a simple Prestashop website where customers buy a number of questionnaires.

We send them an email with a link to fill in their questionnaires in the Laravel app. The Laravel app pulls data from the Prestashop API each hour (to get the latest orders and customer information). The app basically generates PDFs based on the content of the questionnaires.

I feel this could be optimized because at the moment I've to check every order, every customer, every address, etc.. and update if modified.

He asked me to start another project based on the first one, so I'd like to start clean if you guys think there is a better way to achieve this that would make it easier to follow Prestashop changes (at the moment I've to check every order, every customer, every address, etc..) and that would be as synchronized as possible.

Cheers
