Web API

Goal and how to help

One day, eventually, Trackmania will reach his EoL. This is about documenting as much as possible to eventually get the point of having a fully functional custom auth server. If you want to give help, go ahead. Just grab fiddler and start tweaking around with the game.

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

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>
  <auth>
    <value>[...]</value>
  </auth>
</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
- author
  - login is not set when calling GetConnectionAndGameParams
  - session is not set when calling GetConnectionAndGameParams
- request
  - name Name of the requested function.
  - param Parameters for the call.
- auth Optional. Only seen with Disconnect
  - value Looks like an auth ticket.

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>
</r>

Here is a description of the return:

r
- r
  - n The name of the called function
  - c The return data
- e A string giving the execution time.
