Campaign Guides

Invite & Earn

The following documentation contains guides for implementing and testing the Invite & Earn Campaign in a React Native Project.


• App setup with the Flyy SDK. Setup Guide.
• An Invite & Earn Campaign running.


The referral process starts when the Referrer (User A) shares their referral link from the Offers Page on the app.

After User A has shared the link containing the Referral code, the Referee (User B) can apply the referrer's code in one of the following two ways.

  1. By manually typing in the referral code.
  2. Automatically when the app is downloaded and installed from App Store or Play Store using the referral link.

Next, the user Signs Up and performs the Event, say, updating their KYC, which will complete this process and distribute the rewards.

The above makes up the complete referral process.

The referral process on User B's device is summarized in the diagram below. The developer should ensure that User B executes these steps in the exact order for a successful referral.



Step 1: Initialize with initFlyySDKWithReferralCallback

This step takes care of one of the two ways a referral code is automatically applied. Use the initFlyySDKWithReferralCallback to initialize the SDK instead of the initFlyySDK method.


iOS 14.5+

Due to Apple's App Tracking Transparency Policy introduced from iOS 14.5, referral links might not work. Users should therefore be allowed to manually set the referral code as explained in Step 2 below.

Use the callback to perform additional UI-related actions, such as verifying the incoming referrer code.

The referrer's code is automatically applied.

Flyy.initSDKWithReferralCallback("<partner_id>", Flyy.STAGE,
  (referralData) => {
      (isValid, referralCode) => {
        console.log(isValid, referralCode);

Step 2: Set Referral Code

This step takes care of the other way where the referral code is manually applied.

If the user is required to apply the referral code manually, the setFlyyReferralCode method should be used as follows.

However, note that the setFlyyReferralCode method must be called before calling setNewUser.

  (isValid, referralCode) => {
    if (isValid) {

Step 3: Sign Up

When working with an Acquisition Module campaign, a new user must register with the setNewUser method instead of setUser.


Step 4: Trigger Event

The final step to completing the referral process is triggering an event. The rewards will be distributed only after the campaign event is sent.

//Note: Only use the sendEvent method in Staging. For production, make
//an API call from your backend.
Flyy.sendEvent(eventId, "true");

Variant Campaign Event

Follow this step only to implement the variant campaign.

From the implementation standpoint, there is just 1 difference when working with Variant Campaigns: the sendEvent method expects Event Data as a JSON object.

The below code sample is about the Variant Campaign created here from the Dashboard.

Flyy.sendEvent("purchase", <JSON.stringify(data)>);

After the 4th step, the Flyy Rewards System sends out a scratch card to the Referrer (User A) and Referee (User B).

The Flyy Rewards System performs a few checks to determine whether new users are eligible before giving out the rewards. You may run into these safeguards while testing the Invite & Earn implementation. If you do, you may find possible resolutions in the Test Invite & Earn and the Troubleshooting sections.

Test Invite & Earn


  • Two physical devices — one for User A and one for User B.

Use the below 4 steps to test this offer in your app or download the sample project from GitHub.

The Flyy Rewards System requires that the mobile device used for registering a user should not have been used before for registering any other user. See the Troubleshooting section to learn how to remove users previously registered using the same device.

Test with your app

On User A's device

  • Sign Up and check the Offers Page screen to get the Referral Code.

The referral link will look something like this: <>.
In this example link C8UFPBE is user A's referral code.

On User B's device

  • Apply the Referral Code shared by User A.
  • Perform Sign Up.
  • Perform the action on User B's device that triggers the "kyc_done" event.

After the event is triggered, the Flyy Rewards System will check if this is a genuine referral and give out the reward containing a Scratch Card and notification to User A and B's devices.

Test with the GitHub Project

Download the React Native Project from GitHub.

Set up FCM notifications and App Store app and Play Store app redirects before starting the test.

Set up FCM Notifications

In your staging dashboard, go to Settings > SDK Keys and provide the following server key:


Redirect to Store Links

Find out how to perform these steps for the iOS app and Android app from these links.

Then, perform the following steps.

On User A's device

  • Run the project.
  • On the SDK Setup screen, type in the Package Name and Partner Id as it appears in your Staging dashboard.
  • Sign Up with a new User ID.
  • Tap the Invite & Earn button, open the Offer, and Share the Referral Link.

On User B's device

  • Tap on the Referral Link. The link should open on the Safari browser for iOS, but it will show an error as we left the app store link field empty. For Android, the link will redirect to the App Page in the Play Store -- but do not download the app.
  • Run the app from the terminal.
  • Type in the Package Name and Partner Id. Click Next. An alert message will be displayed whether the Referral Code is valid or invalid. If the Referral Code is valid, it is applied without further steps.
    • If the referral code is invalid, manually enter the referral code on the Sign-Up screen.
  • Sign Up with a new User ID.
  • On the Home screen, tap the Send Event button. This button is calling the sendEvent method with "kyc_done" as the event key in its parameter.

After tapping on the Send Event button, the Flyy Rewards System determines whether to give out the reward or not and sends a Scratch Card and notification to User A and B's devices.


Suppose you are not receiving rewards during testing. See the common problems below.

Multiple Devices with the same Device ID

Users A and B must sign up from unique devices and the same device should not exist on Flyy's dashboard before they sign up.

To verify the uniqueness of the device id, go to Settings > Playground and follow these steps:

  1. Perform a Search with User A's user id.
  2. Copy the Device Id from the search result.
  3. Perform another search with the copied Device Id.
  4. If more than 1 search results show up, delete all records with identical Device Id.

Repeat the same steps for User B.

After you have ensured that all records with the above Device Ids have been deleted, rerun the test.

Notification Issue

Go to Reports > Referrals and check if the new referral record with User A and B is created. If the new record exists, but the devices do not receive a notification, test your app's FCM configuration.

Also, ensure that the correct Server Key has been provided at Settings > SDK Keys.

To test notifications from the dashboard.

  • Go to Settings > Playground from the dashboard.
  • Search by User Id.
  • Click "Test FCM". Note that at least 1 Campaign must be active.
