could somebody help me with Facebook API, how to get relationship status of friends(single, married, etc...)?
Thanks for any help.
You just need to get an access token with user_relationships, call https://graph.facebook.com/YOURFRIEND-ID and check "relationship_status" in the returned JSON string. Just have in mind that if your friend didn't filled his relationship data into his profile, there will be no "relationship_status" at the returned user info.
