# Setting up the server side handlers and functions

There are multiple examples shown in the config, and it is already prepared to ESX frameworks using OX Lib and OX Inventory

```lua
Config.RemoveMoney = function(source, amount) -- remove money function, you can set your inventory here as you like
    exports.ox_inventory:RemoveItem(source, 'money', amount) -- xPlayer.removeInventoryItem('money', count)
end

Config.GetMoney = function(source) -- get the money, always returns a number, you can set here your inventory as you like
    local money = exports.ox_inventory:GetItem(source, 'money', nil, true) -- xPlayer.getInventoryItem(item).count
    return money
end

Config.Query = function(source, data)
    -- you can put your custom query with your data-s, encode the data table to find which values are in it.
    -- the query must be a STRING, and the additional informations must be in a table as the example shows.
    local xPlayer = ESX.GetPlayerFromId(source) -- QBCore.Functions.GetPlayer(source)
    local owner = xPlayer.identifier -- QBCore.Functions.GetIdentifier(source)

    local properties = data.properties
    local plate = data.plate
    local query = 'INSERT INTO owned_vehicles (owner, plate, vehicle) VALUES (?,?,?)'
    return query, {owner, plate, json.encode(properties)}
end
```
