Web API

The TrackMania Forever game client uses a XML-RPC based web API to communicate with the master server. This article attempts to document the API with the potential goal of eventually having a fully functional custom master server.

Basic concepts

TrackMania uses a XML-RPC based protocol to authenticate players, load server lists, load rankings, etc. Below is some documentation about what has been reversed engineered. A lot is still left to be documented, as logged on the Progress page.

The client sends HTTP(S) POST requests to

• http://game.trackmaniaforever.com/online_game/request.php
• http://game2.trackmaniaforever.com/online_game/request.php
• http://nations.trackmaniaforever.com/online_game/request.php

to communicate with the master server, using the headers:

User-Agent: GameBox
Accept: */*
Content-Type: application/binary
Connection: Keep-Alive
Pragma: no-cache

Request body

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <game>
    <name>TmForever</name>
    <version>2.11.16</version>
    <distro>MOLUX</distro>
    <lang>fr</lang>
    <sd>2011-02-21</sd> <!-- Only sent by dedicated server, see below -->
  </game>
  <author>
    [...]
  </author>
  <request>
    <name>[...]</name>
    <params>
      [...]
    </params>
  </request>
  <auth>
    <value>[...]</value>
  </auth>
</root>

Here is a description of the xml:

• root
  • game
    • name The client you are using. Known values: TmForever
    • version Version of the client.
    • distro Software distribution. E.g. MOLUX for TMNF or ORTIC for TMUF.
    • lang Language of the client, as ISO 639-1. Dedicated server sets it to "xx".
    • sd Dedicated Server release date as YYYY-MM-DD, only sent by server.
  • author See #Author.
  • request
    • name Name of the remote procedure.
    • param Parameters for the call.
  • auth Optional. Only seen on Connect and Disconnect.
    • value Looks like an auth ticket.

Author

The author tag identifies the user for whom the request is sent. In this documentation, three cases are possible for the author tag:

• The method doesn't require authentication (denoted as "No (Empty)"), the author tag is filled with following content:

  <login/>
  <session/>
  

• The method requires user name (denoted as "No (Set to 1)"), the author tag is filled with following content:

  <login>the user's login</login>
  <session>1</session>
  

• The method requires authentication (denoted as "Yes"), the author tag is filled with following content:

  <login>the user's login</login>
  <session>the session's id</session>
  

Response body
