This project is a part of The SOOMLA Framework, which is a series of open source initiatives with a joint goal to help mobile game developers do more together. SOOMLA encourages better game design, economy modeling, social engagement, and faster development.

Haven't you ever wanted an in-app purchase one liner that looks like this ?!



SOOMLA's Store Module for Unity3d

March 9th: v1.7.15 Unity 5 compatibility patch.

If you are upgrading an already imported store module, make sure to delete the <project>/Assets/Soomla/compilations folder.

If you get the “API Update Required” window, click the "I Made a Backup. Go Ahead!" button, Unity will automatically update some of our code.

October 29th: v1.7 Work in editor! When you're in the Unity editor, data will be saved to PlayerPrefs.

October 3rd, 2013: iOS Server Side Verification is now implemented into unity3d-store. The server is a complimentary server provided by SOOMLA to help you get your in-game purchases a bit more secured. This feature is not enabled by default. In order to enable Server Side verification go to the Soomla prefab and set ios Server Side Verification -> true.

unity3d-store is the Unity3d flavor of SOOMLA's Store Module.

####Pre baked unitypackages:

If you're upgrading from a version below v1.7.x make sure you take soomla-unity3d-core again.

unity3d-store v1.11.2

From sources:

  • Clone this repository recursively: git clone --recursive
  • Run ./build_all from project directory


If you want to see full debug messages from android-store and ios-store you just need to check the box that says "Debug Messages" in the SOOMLA Settings. Unity debug messages will only be printed out if you build the project with Development Build checked.


There are some necessary files in submodules lined with symbolic links. If you're cloning the project make sure you clone it with the --recursive flag.

$ git clone --recursive [email protected]:soomla/unity3d-store.git

Getting Started

  1. First, you'll need to either download (RECOMMENDED) the unity3d-store pre-baked packages, or clone unity3d-store.
  • RECOMMENDED: Download unity3d-store

    OR, if you'd like to work with sources:

  • Clone unity3d-store from SOOMLA's github page.

    $ git clone --recursive [email protected]:soomla/unity3d-store.git

    There are some necessary files in submodules linked with symbolic links. If you're cloning the project make sure to include the --recursive flag.

  1. Drag the "StoreEvents" and "CoreEvents" Prefabs from Assets/Soomla/Prefabs into your scene. You should see them listed in the "Hierarchy" panel.

    This step is no longer required starting from Store v1.9.0

  1. On the menu bar click Window > Soomla > Edit Settings and change the values for "Soomla Secret" and "Public Key":
  • Soomla Secret - This is an encryption secret you provide that will be used to secure your data. (If you used versions before v1.5.2 this secret MUST be the same as Custom Secret)

  • Public Key - If your billing service provider is Google Play, you'll need to insert the public key given to you from Google. (Learn more in step 4 here). Choose both secrets wisely. You can't change them after you launch your game!

  • Fraud Protection - If your billing service provider supports Fraud Protection, you can turn on this option and provide needed data. Optionally, you can turn on Verify On Server Failure if you want to get purchases automatically verified in case of network failures during the verification process.

    In order to get clientId, clientSecret and refreshToken for Google Play go over Google Play Purchase Verification.

  1. Create your own implementation of IStoreAssets in order to describe your game's specific assets.
  • For a brief example, see the example at the bottom.

  • For a more detailed example, see our MuffinRush example.

  1. Initialize SoomlaStore with the class you just created:

    SoomlaStore.Initialize(new YourStoreAssetsImplementation());

    Initialize SoomlaStore in the Start function of MonoBehaviour and NOT in the Awake function. SOOMLA has its own MonoBehaviour and it needs to be "Awakened" before you initialize.

    Initialize SoomlaStore ONLY ONCE when your application loads.

  2. You'll need an event handler in order to be notified about in-app purchasing related events. Refer to the document about Event Handling for more information.

That's it! You now have storage and in-app purchasing capabilities ALL-IN-ONE!

###Unity & Android

Starting IAB Service in background

If you have your own storefront implemented inside your game, it's recommended that you open the IAB Service in the background when the store opens and close it when the store is closed.

// Start Iab Service

// Stop Iab Service

This is not mandatory, your game will work without this, but we do recommend it because it enhances performance. The idea here is to preemptively start the in-app billing setup process with Google's (or Amazon's) servers.

In many games the user has to navigate into the in-game store, or start a game session in order to reach the point of making purchases. You want the user experience to be fast and smooth and prevent any lag that could be caused by network latency and setup routines you could have done silently in the background.

Unity & Windows Phone 8


This WP8 plugin work on Unity 4.5.4 and above 4.x versions.

For Unity 5 the plugin work with 5.0.1p1 patch release 1 version and above.

To build for WP8 target you need to configure the assemblies with the new plugins setting panel introduce in the 5.0 version.

For Assets/Plugins/soomla-wp-core.dll Check Editor platform only

For Assets/Plugins/wp-store.dll Check Editor platform only

For Assets/Plugins/WP8/soomla-wp-core.dll Check WP8Player platform only and select Assets/Plugins/soomla-wp-core.dll for the Placeholder

For Assets/Plugins/WP8/wp-store.dll Check WP8Player platform only and select Assets/Plugins/wp-store.dll for the Placeholder

IAP Test Mode

To activate the IAP Test Mode select the checkbox in the Soomla Config Panel. Declare your test IAP in Assets/Plugins/WP8/IAPMock.xml

Simulator build

To run your app in the simulator select the checkbox in the Soomla config panel. This option copy the right assembly into the Assets/Plugins/WP8/ folder

Clone and Develop on Windows (workaround)

One major issue is that Git didn't manage symlink on Windows...

Before launching Unity you have to run "fix-symlinks-windows\setup-symlinks.bat" from the root of the repo in a Git bash. If you forget to call it before launching Unity, just close Unity and delete the Library folder.

When you want to restore the repo at it's initial state run "restore-symlinks.bat"

Keep in mind that modifications in symlink single files or not copied, you have to copy them before restoring symlinks!

One last thing is that this script didn't follow symlink in submodules of submodules, you can still have missing files.

Unity & iOS

  • If you are building your app under Windows, you have to have iTunes installed since the SOOMLA postprocessing is expecting a utility that exists in OS X and is installed with iTunes in Windows.

What's next? In App Purchasing.

When we implemented modelV3, we were thinking about ways that people buy things inside apps. We figured out many ways you can let your users purchase stuff in your game and we designed the new modelV3 to support 2 of them: PurchaseWithMarket and PurchaseWithVirtualItem.

PurchaseWithMarket is a PurchaseType that allows users to purchase a VirtualItem with Google Play or the App Store.
PurchaseWithVirtualItem is a PurchaseType that lets your users purchase a VirtualItem with a different VirtualItem. For Example: Buying 1 Sword with 100 Gems.

In order to define the way your various virtual items (Goods, Coins ...) are purchased, you'll need to create your implementation of IStoreAsset (the same one from step 4 in the "Getting Started" above).

Here is an example:

Lets say you have a VirtualCurrencyPack you call TEN_COINS_PACK and a VirtualCurrency you call COIN_CURRENCY:

VirtualCurrencyPack TEN_COINS_PACK = new VirtualCurrencyPack(
	            "10 Coins",                    // name
	            "A pack of 10 coins",      // description
	            "10_coins",                    // item id
				10,								// number of currencies in the pack
	            COIN_CURRENCY_ITEM_ID,         // the currency associated with this pack
	            new PurchaseWithMarket("com.soomla.ten_coin_pack", 1.99)

Now you can use StoreInventory to buy your new VirtualCurrencyPack:


And that's it! unity3d-store knows how to contact Google Play or the App Store for you and will redirect your users to their purchasing system to complete the transaction. Don't forget to subscribe to store events in order to get the notified of successful or failed purchases (see Event Handling).

Storage & Meta-Data

When you initialize SoomlaStore, it automatically initializes two other classes: StoreInventory and StoreInfo:

  • StoreInventory is a convenience class to let you perform operations on VirtualCurrencies and VirtualGoods. Use it to fetch/change the balances of VirtualItems in your game (using their ItemIds!)
  • StoreInfo is where all meta data information about your specific game can be retrieved. It is initialized with your implementation of IStoreAssets and you can use it to retrieve information about your specific game.

The on-device storage is encrypted and kept in a SQLite database. SOOMLA is preparing a cloud-based storage service that will allow this SQLite to be synced to a cloud-based repository that you'll define.

Example Usages

  • Get VirtualCurrency with itemId "currency_coin":

    VirtualCurrency coin = (VirtualCurrency) StoreInfo.GetItemByItemId("currency_coin");
  • Give the user 10 pieces of a virtual currency with itemId "currency_coin":

    StoreInventory.GiveItem("currency_coin", 10);
  • Take 10 virtual goods with itemId "green_hat":

    StoreInventory.TakeItem("green_hat", 10);
  • Get the current balance of green hats (virtual goods with itemId "green_hat"):

    int greenHatsBalance = StoreInventory.GetItemBalance("green_hat");

Event Handling

SOOMLA lets you subscribe to store events, get notified and implement your own application specific behavior to those events.

Your behavior is an addition to the default behavior implemented by SOOMLA. You don't replace SOOMLA's behavior.

The 'Events' class is where all event go through. To handle various events, just add your specific behavior to the delegates in the Events class.

For example, if you want to 'listen' to a MarketPurchase event:

StoreEvents.OnMarketPurchase += onMarketPurchase;

public void onMarketPurchase(PurchasableVirtualItem pvi, string payload, Dictionary<string, string> extra) {
    // pvi is the PurchasableVirtualItem that was just purchased
    // payload is a text that you can give when you initiate the purchase operation and you want to receive back upon completion
    // extra will contain platform specific information about the market purchase.
    //      Android: The "extra" dictionary will contain "orderId" and "purchaseToken".
    //      iOS: The "extra" dictionary will contain "receipt" and "token".

    // ... your game specific implementation here ...

NOTE: One thing you need to notice is that if you want to listen to OnSoomlaStoreInitialized event you have to set up the listener before you initialize SoomlaStore. So you'll need to do:

StoreEvents.OnSoomlaStoreInitialized += onSoomlaStoreInitialized;


Soomla.SoomlaStore.Initialize(new Soomla.Example.MuffinRushAssets());
