I'm using the public RoVer api right now, and it returns a table like this :
{"status":"ok","robloxUsername":"evaera","robloxId":92658764}
and I need to know if roblox automatically converts this table to a dictionary or not, if not, is there a way.
That looks like JSON. Yes, it can convert it. HttpService has a function named JSONDecode: its first argument should be a string containing the JSON. It returns the converted table.
