I'm building a webapp which lets users search for properties for sale, on a map. I want to be able to share the searches on Facebook and tag my friends, so for example I can say "I am searching for a house in Liverpool with [FB Friends]".
I've looked at https://developers.facebook.com/docs/opengraph/guides/tagging/#mentions for help tagging, but it seems to imply that I need a place ID to be able to tag people. It works if I infer the place using the Latitude/Longitude of my search, but is that acceptable?
I wasn't sure after reading the rules if I have to actually be in a place to tag it in a post.
Is it possible to create a post with the Graph API and tag friends, without having to add a Place ID?
According to this document, I think it is impossible to do that. In the 'Create' section, parameter 'tags' is noted that it should be used with parameter 'place'.
