How does Facebook copy the URL, TEXT and Image from a URL.

Hey, I have this page where I am trying to keep members up to date on local Covid-19 news stories.

I am using Inoreader to find the content and elink.io to create the feeds. Both work well.

But I would like to code this myself.
It should be pretty easy it’s just a repeater with the image, URL path and title for each web page.
It’s what you paste in Facebook, how do they get this information in one copy and paste of the URL?

Can anyone help me out?
Thanks in advance!
Sylvia
