Web API

Basic concepts

TrackMania uses a XML-RPC-like API to authenticate players, load server lists, load rankings, etc... Here is some documentation about what has been reversed engineered. A lot is still left to be documented.

The game sends unencrypted POST requests to

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

to communicate with the API.

It sets two headers: User-Agent: GameBox and Accept: */*, and uses the following format as 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>
  </game>
  <author>
    <login/>
    <session/>
  </author>
  <request>
    <name>[...]</name>
    <params>
      [...]
    </params>
  </request>
</root>

Here is a description of the parameters :

• root
  • game
    • name: the client you are using. Known values: TmForever
    • version: Version of the client
    • distro: Unknown. Set to MOLUX or TAHOR
    • lang: lang of the client, as ISO 639-1

    • session: obtained by calling GetConnectionAndGameParams. Unset when calling that function.
  • request:
    • name: Name of the requested function.

The server responds with XML, which has obfurscated names:

<?xml version="1.0" encoding="UTF-8"?>
<r>
  <r>
    <n>[...]</n>
    <c>
      [...]
    </c>
  </r>
  <e>execution time : 0.0010 s</e>
