Hello Jason!
I understand that you’re new to Wix (and WixCode especially) so first of all - Welcome!
Now, let me assist you by directing you to a few articles that I think might be helpful to your goal of working with our database system.
Wix Code: About Connecting Page Elements to Database Content
Wix Code: About Database Collections
WixDataQuery API
As for integrating your site with 3rd-party services, we have a special method for that, its called wix-Fetch . Check it out!
One last thing, although similar by name, the coding language we use in Wix is actually JavaScript (JS).
In order to use our API’s you need to have some basic coding skills that can be easily taught via the internet. You can also check WixCode’s Youtube channel for simple tutorials.
Hope that helps!
Doron.
