I am trying to configure a plugin for a server that involves a few things. First, I need to get information from the player as soon as they connect and also when they disconnect from a server. The information I need is: the server they have entered or left, username of the player, UUID of the player, and if they connected or disconnected. Lastly, it involves going from http post request to json body. I am new to plugin development and would love any help or advice! Thank you in advance!
