Unity SDK

Getting Started#

Supported versions#

TapResearch only supports Unity v2017.4.0f1 and above.

Download the SDK#

You can download the latest version of the TapResearch Unity SDK on GitHub.

Integrate TapResearch#

Inside the TapResearchSDK directory, you will find Tapresearch.unitypackage. You can import the package by selecting Assets > Import Package > Custom Package... through the Unity menu.

Library Dependencies#

The SDK uses External Dependency Manager for Unity to integrate the native library dependencies. If the dependency manager is already installed on your app, you can remove the Dependency Manager files when importing the SDK. For the Android build, make sure the dependencies have been resolved by going to Assets => External Dependency Manager => Android Resolver => Resolve. For iOS, the plugin will add CocoaPods to the project and will import the dependencies in the Xcode project.

iOS Project Setup#

  • Ensure you have the following inside the Assets > Plugins > iOS folder:
    • TapResearch.framework
    • TRUnityBridge.mm


The TapResearchSDK includes a post-process script that runs after compilation to add required frameworks and linker flags for iOS. If you're using a Windows machine to generate the Xcode project or if the script fails, you'll need to add the frameworks and set the linker flags manually.

  • Add the following frameworks to Target > Build Phases > Link Binary With Libraries:
    • Foundation.framework
    • UIKit.framework
    • SystemConfiguration.framework
    • MobileCoreServices.framework
    • AdSupport.framework
    • Security.framework

Linker Flags#

  • Select the build settings tab and type in Other Linker Flags in the search field.
  • Add the following flag.
    • -ObjC

Android Project Setup#

  • Ensure you have the following inside the Assets > Plugins > Android folder:
    • tapresearch.aar
    • unitybridge.aar

Initialize TapResearch#

Initialize the TapResearchSDK as early as possible. Please note that the Configure() method only needs to be called once on app launch. Also, your iOS and Android apps have different API tokens. Use pre-processor directives so Unity knows which API token to use when you build your app.

using TapResearch;
const String ApiToken = "ios_api_token";
const String ApiToken = "android_api_token";
public class MyMainController : MonoBehaviour {
public void Awake()

The next step will be to set a unique user identifier. Please note that without a unique identifier, the survey wall won't be available.


Our system only accepts User IDs with ASCII characters. If necessary, you can convert it to BASE64 before sending the User ID to us.


A Placement is an object that should be attached to the app's call to action that will direct the users to TapResearch.

To view the available placements or creating a new one, navigate to the app settings in the Supplier Dashboard, and copy the placement's identifier.

The Placement is encapsulated in the TRPlacement object which contains metadata and the method to display the survey wall.

Initialize a placement#

To initialize a placement, it is best practice to call the SDK as late as possible before displaying the placement in the app. For example, you can initialize it in the Start method of the scene where the placement will be visible.

public TRPlacement tapresearchPlacement;
void Start()
TapResearchSDK.OnPlacementReady = this.OnPlacementReady;
void OnPlacementEventReady(TRPlacement placement)
//You can now store this placement to be shown with your Survey Wall.

More About Placements#

  • The survey wall may or may not be available to a specific user and it's important to check survey availability before displaying the call to action.

  • A placement can only show the survey wall one time. Once the survey wall is dismissed, you'll have to initialize a new TRPlacement object if you wish the user to go back to TapResearch.

Display the survey wall#

To display the survey wall, call the ShowSurveyWall on your TRPlacement object.


Going Live#

Learn how to take the app live.

Hot Survey#

hasHotSurvey is a placement attribute that indicates a special high-yield survey is available for this user. When this attribute is true, the user should be shown a special call to action to encourage them to take advantage of this opportunity. These special survey opportunities may only be available for a few minutes, so initPlacement should be called whenever the parent view is loaded. If you want to use Hot Surveys, please contact developers@tapresearch.com.


Server to server callbacks#

You can read more about server to server callbacks.


Placement Delegate#

A new delegate has been added which is used by the SDK to let the app know a placement is ready or not available.

You no longer need to initialize a placememt manually. When implementing the delegate, you callbacks will alert you of a new placement for you to store its status. Placements are now passed at the time of showSurveyWall() with a new method overload.

public delegate void PlacementDelegate(TRPlacement placement);
public static PlacementDelegate OnPlacementReady;
public delegate void PlacementEventDelegate(TRPlacement placement);
public static PlacementEventDelegate OnPlacementEventReady;
public delegate void ExpiredPlacementDelegate(String expiredPlacement);
public static ExpiredPlacementDelegate OnPlacementEventUnavailable;

When implementing the delegate, you callbacks will alert you of a new placement for you to store its status. Placements are now passed at the time of showSurveyWall() with a new method overload.

public static void ShowSurveyWall(string placementIdentifier) { }

Reward Callbacks#

The SDK will check if the user has unredeemed rewards in the following events:

  • On SDK initialization
  • When the user exits TapResearch

The RewardListener interface is the reward listener that will handle the new rewards that the player earned in a session. The object that implements the interface should be passed to TapResearchSDK.getInstance().setRewardListener to get activated.

The reward information will be encapsulated in the TRReward object with the following methods:

Method nameTypeDescription
TransactionIdentifierStringThe reward unique identifier
CurrencyNameStringThe virtual currency name
PlacementIdentifierStringThe placement that started the session identifier
RewardAmountintThe reward amount in virtual currency. The value will automatically be converted to your virtual currency based on the exchange rate you specified in the app settings.
PayoutEventintThe action that the user was rewarded for. 0 - Profile Complete, 3 - Survey Complete.

public class MyMainController : MonoBehaviour {
public void Awake() {
TapResearchSDK.Configure (YOUR_API_TOKEN);
TapResearchSDK.OnReceiveReward = this.OnReceiveReward;
private void OnReceiveReward(TRReward reward) {
Debug.Log ("You've earned " + reward.RewardAmount + " " + reward.CurrencyName + ". " + reward.TransactionIdentifier);

It is important to note that onReceiveReward will be called back-to-back if the player completed multiple surveys in one session.

Survey callback (Optional)#

Assign a delegate if you want to be notified when the survey wall status changes.

public class MyMainController : MonoBehaviour {
public void Start() {
TapResearchSDK.OnSurveyWallOpened = this.OnSurveyWallOpened;
TapResearchSDK.OnSurveyWallDismissed = this.OnSurveyWallDismissed;
private void OnSurveyWallOpened () {
// Stop music, timers, etc.
private void OnSurveyWallDismissed () {
// Start music, timer, etc.

Customize the survey wall#

If you wish to customize the look of the survey wall modal to fit with the rest of your game, use the following:

TapResearchSDK.SetNavigationBarText ("Title");
TapResearchSDK.SetNavigationBarTextColor ("#00ffff");
TapResearchSDK.SetNavigationBarColor ("#ff7f50");

Screen Orientation#

To force the application to render in landscape mode only, it would be better to use the following screen orientation guide instead of disabling the portrait orientation in the player settings. TapResearch works better in portrait mode so using the player settings may result in some problems rendering the surveys.

Android Debug Console Output#

To output debug info to logcat when generating an Android build, use the following:

TapResearchSDK.SetDebugMode (true);

Upgrade to v2.4.2#

  • Exposed version string as public.
  • Fixed a bug affecting Nav bar color customization.
  • iOS race condition during init rarely affecting rewards and offers.
  • Relocated TestButtonClick.cs to Plugins/TapResearch/TRExamples directory.
  • Note: you can remove the old mainscene/TestButtonClick from Assets directory.

Upgrade to v2.3.0#

  • A new Delegate has been added for handling the readiness of all placements. The SDK will fetch placements for you and alert you of their readiness.
public delegate void PlacementDelegate(TRPlacement placement);
  • A new method was added for passing placements at the time of showing your SurveyWall.
public static void ShowSurveyWall(string placementIdentifier) { }

Upgrade to v2.1#

  • In every file that will reference the SDK, add using TapResearch. All the SDK classes are under the TapResearch namespace.
  • The SDK API class was changed from TapResearch to TapResearchSDK. e.g. TapResearch.Configure is now TapResearchSDK.Configure
  • Delete the following files from the previous SDK
    • TapResearch.cs
    • Assets/Plugins/Android/tapresearch.aar
    • Assets/Plugins/Android/unitybridge.aar
    • Assets/Plugins/Android/play-services-ads-lite-10.2.6
    • Assets/Plugins/Android/play-services-basement-10.2.6
    • Assets/Plugins/iOS/TapResearchSDK.framework
  • Check the library dependency manager section for more info about library dependencies.

Test Devices#

Before you are ready to go live, the SDK can only work with a test device. Navigate to your dashboard and click the Add Devices button. Add a device name and a unique user identifier or a Google Advertising ID / Apple IDFA. Now, when you enter our survey flow through your app, you will be able to complete a test survey and receive a test reward when you re-open your app.


Survey wall isn't available#

If placement.IsSurveyWallAvailable is false, please reference the Android or iOS integration guides for further steps.
