I'm using JSON api plugin to pull data from wordpress into an app I am making. I need a unique identifier to make sure I don't have any duplicates WHILE also using the identifier as a way to sort from newest post to oldest post. As of right now I'm confused because I pull the 10 most recent posts. I then take the ID and I attempt to reach example.com/?id=1774 but I don't get the correct post. I get a different one. I'm starting to run out of ideas?
