Login API for the ROBLOX 2014 client.

Usage

URL format: */mobileapi/login

Method: POST

Example body: username=testuser&password=hello

Example Success JSON:

{ "Status": "OK", "UserInfo": { "UserName": "testuser", "UserPassword": "hello", "UserID": 1, "RobuxBalance": 150, "TicketsBalance": 12000, "IsAnyBuildersClubMember": true, "ThumbnailUrl": "https://14blox.strangled.net/getUserAvatarImage?userId=1" } }

Example Fail JSON:

{ "Status": "InvalidPassword", "UserInfo": { "UserName": "testuser", "UserPassword": "hello", "UserID": 1, "RobuxBalance": 150, "TicketsBalance": 12000, "IsAnyBuildersClubMember": true, "ThumbnailUrl": "https://14blox.strangled.net/getUserAvatarImage?userId=1" } }

Notes

I don't know why, but ROBLOX requires the UserInfo to have the user's data even when the password is invalid :/
