        If you just want to call the REST-Server you can do it with: `https://tm-voting.willers.digital`.
        ## REST Services
        There are currently only two REST interfaces.
        ⚠ **All parameters can be done in the url query `/getVotes?map=blah` or in the Body you sent in a JSON format `{"map":"blah"}`**
        **POST /getMapInfo**<br>
        **GET /getVotes**<br>
        Returns the current voting status for the current map.<br>
        Example Request:
        ```
        | Parameter | Type | Description | Example
        |------------ |------- |------------------------------------- |-----------------------------
        | map | String | The map UID to show the votes on it | `OkNwgzSwDLZSWSRPsUKY7EA1Cg5`
        Example response:
        ```json
        {
        "mapId": "currentMapUId",
        "userId": "UserLogin",
        "name": "mapname for example: Summer 2021 - 01"
        "mapUid": "OkNwgzSwDLZSWSRPsUKY7EA1Cg5",
        "votes": 53,
        "average": 85,
        "lastVoteDate": "2021-08-23T00:28:16.273Z"
        }
        ```
        Info: I heard that the name is not really relevant, because the API of trackmania.io already provides information about a map. Nevertheless, in the current implementation this field should at least not be null.
        **POST /setVote**<br>
        Writes the vote of a player to the respective map into the database table.
        Example Request:
        ```
        **GET /getPlayerVote**<br>
        Returns the current voting status of a player for the current map.<br>
        | Parameter | Type | Description | Example
        |------------ |------- |------------------------------------- |-----------------------------
        | map | String | The map UID to show the votes on it | `OkNwgzSwDLZSWSRPsUKY7EA1Cg5`
        | player | String | The player login that he voted on it | `Jtmn3kBnSSadky_mLNhp_A`
        Example response:
        ```json
        {
        "mapId": "currentMapUId",
        "userId": "UserLogin",
        "name": "mapname for example: Summer 2021 - 01",
        "vote": 40
        "mapUid": "OkNwgzSwDLZSWSRPsUKY7EA1Cg5",
        "playerLogin": "Jtmn3kBnSSadky_mLNhp_A",
        "vote": 50,
        "date": "2021-08-23 04:55:49.105"
        }
        ```
        **POST RESPONSE**<br>
        The response is the same in both cases:
        ```
        **GET /mostVotedMaps**<br>
        Returns the top most voted maps. in decreasing order (from the most voted map to the least voted map)<br>
        There's no parameters for this request!
        Example response:
        ```json
        {
        "votes": 3,
        "average": 63,
        "vote": 80
        "OkNwgzSwDLZSWSRPsUKY7EA1Cg5": 65,
        "7fsfRSUCQ7YwfBEdRk_GivW6qzj": 56,

        "Iwo4gO_0dQ3FVQ1xeYjho5ZmLrf": 1,
        }
        ```
        If other players only listen to the current voting status on the map, the vote for the respective client is not returned, since this is client-specific and therefore not interesting for everyone. So for them the response will be like:
        **GET /mostPlayerVoted**<br>
        Returns the top of the players who have voted the most maps. in decreasing order (from the most player who voted to the least)<br>
        There's no parameters for this request!
        Example response:
        ```json
        {
        "Jtmn3kBnSSadky_mLNhp_A": 10,
        "W01C9MLeQH2zZ8v_P-gXvA": 8,

        }
        ```
        **POST /setVote**<br>
        Writes the vote of a player to the respective map into the database table.<br />
        | Parameter | Type | Description | Example
        |------------ |------- |------------------------------------- |-----------------------------
        | map | String | The map UID to vote | `OkNwgzSwDLZSWSRPsUKY7EA1Cg5`
        | player | String | The player login that it will vote | `Jtmn3kBnSSadky_mLNhp_A`
        | vote | Number | A number between 0 and 100 to define the vote | `56`
        Example Response:
        ```json
        {

        My backend is really not secure for SQL-Injection and some other secure stuff. If some more people want to use it, I should protect it more.. but that take some time. You are welcome to help me with this. That would be a nice thing if we can introduce a global map vote functionality in a secure and highly available way. :)
