3.2. How to launch the Shop

There are 3 ways of launching a game's shop:

• 1. Launch the shop at the IDC Games platform (not recommended).

• 2. Launch the shop at the game's browser or at an external browser.

• 3. Launch the shop at the IDC Games launcher.

1. At the IDC Games platform

With this option, the user is directed to the game's shop URL at the platform (web) to make a purchase, where he has to log in before making the purchase. The IDC Games platform will then make an http request to the developer's server, where the developer has to define the callback with the details of the transaction and send the answer to IDC Games. This option is not recommended because the user is not always loged in when making a purchase attempt, and having to log in can disencourage him from completing the process.

2. At the game's browser or at an external browser

The shop is launched with the following code, where "game" is the game's ID:

https://admin.idcgames.com/shop/frontend/index?game=1118&useridc=4583837&tokengame=0664f0c099d3e0a45c4662a189632c03
$md5data = ("$game_secret$useridc$game");
tokengame=md5($md5data);
$token = md5($md5data);
$shopUrl = "https://admin.idcgames.com/shop/frontend/index?";
$urlparams = "game=$game&useridc=$useridc&tokengame=$token";

The developer has to define the callback at the Panel.

Parameters of the answer

Upon a purchase completion, the game will receive callback to the endpoint provided with a POST request wiht a Json inside that will look like this:

{
"action":"idcpayment",
"useridc":"154777",
"gamer_ip":"193.219.96.100",

3. At the IDC Games launcher

These are the necessary steps in order to use IDCLauncher Shop. IDC Games Launcher must be executed if you want to use these functions.

• 1. Create callback function (see OnPurchaseNotify function code). This is the function that will be called every time that a new notification is received.

• 2. Activate notifications (see activatePurchaseNotifications function code). Before opening the shop notifications must be configured, since all the purchase notifications will be received by the callback configured there. Once you activate notifications you will receive all pending purchase notifications for the user. Every purchased element must be added to the user inventory. Once items are added to the user inventory, the transaction must be closed to change it's status from pending to closed.

• 3. Open shop (see openShopPurchase function code). This function will open IDCGames Launcher shop. If the user makes a successfull transaction, a new purchase notification will be received.

• 4. Close transaction (see closeShopTransaction function Code). This function is used to notify idcgames that an item has been successfully assigned to a user. Once that an item has been assigned to the user, transaction must be close to avoid receiving repeated purchase notifications.

[DllImport("idclib_64.dll", CharSet = CharSet.Ansi)]
        private static extern int activatePurchaseNotifications(string gameId, string gameSecret, int type, NotifyCallBack callBack);


        [DllImport("idclib_64.dll", CharSet = CharSet.Unicode)]

            {
                this.Invoke(new Action(() => this.OnPurchaseNotify(userId, transactionId, idcPaymentId, data, len)));
                return;
            }

            if (len > 0)
            {

            int ret = shopPurchase(tShopTransactionId.Text, extra,userLevel);
            if (ret != 0)
            {
                ShowError("Error creating shop transaction");
            }
        }

        private void closeShopTransaction(string userId, string transactionId, string idcPaymentId)
        {
            //userId        - User Id in IdcPlatform. Received in IDCLogin

            }
            else
            {
                ShowError("Error closing transaction");
            }
        }

Configure the notification of payment events

There are 2 ways of receiving payment notifications:

• DLL event, which invokes a function where the items of the purchase are notified. If a purchase takes place at the web and the game is not launched at the time, the DLL event will receive the notification upon the next launching of the game.

• Callback URL (optional). Add a Callback URL at the panel which contains within all the the information related to a purchase.
