Hi,
Trackserver understands a couple of different protocols, some of which are better documented than others. In any case, I do not provide this information, but you should turn to the source of the app or service in question.
The only protocol that’s properly documented is MapMyTracks: https://github.com/MapMyTracks/api
TrackMe, OsmAnd and SendLocation use a simple HTTP GET protocol. The easiest way to find out about the used parameters and authentication methods is to look at Trackserver’s source: https://github.com/tinuzz/wp-plugin-trackserver/blob/master/trackserver.php
Good luck with your app! If you’re making it available publicly or as open source, I’d be very interested to hear about it.
Best regards,
Martijn.
