I am working on a web app where this is one of the features i want to have, but the biggest issue i’m facing is that the same post from different instances have different id, and I am not sure if there is a way to get the id of a post in a different instance… If anyone has an idea of how to do this I’d love to know!

The one without the @ part should be the community from your instance (e.g. if your account is in lemmy.ml then it is [email protected]). Since it is local, they just do not display the @ part
