Wanting to get into developing plugins and have a friend that made an app using the tapatalk api for forum reading. Question is this: How can I setup the plugin to recognize his client from tapatalk's to display the correct information that he is on his app and not on tapatalk. Do I need him to add some code to his app to send to the server to set a variable? Sorry that this question probably sounds like its coming from a noob but as far as writing plugins, I am. Any help would be appreciated.
