Answer 1

Facebook has now a Server-Side API: https://developers.facebook.com/docs/marketing-api/server-side-api/get-started

Implementing this is similar to implementing the offline events outlined in the accepted answer.

Keep in mind that it will always be cumbersome to track and connect events from the browser and from your server. You need to share a unique user id between the browser and server, so that Facebook (or any other analytics provider) will know that the event belongs to the same user.

Tools like mixpanel.com and amplitude.com may be more tailored to your needs, but will get very expensive once you move out of the free tier (100+ EUR at mixpanel, 1000+ EUR at Amplitude, monthly). Those tools are tailored towards company success, whereas Facebook is tailored towards selling and measuring Facebook ads.
