User properties are attributes you can set on a user level. You can send user properties to third-party platforms and use them in Qonversion for customer segmentation and analytics.
Here is an example of user properties:

Usage

There are two types of user properties: Qonversion-defined and custom user properties.

Defined User Properties

We defined some common case properties and provided API for adding them:

Qonversion.shared().setUserProperty(.email, value: "[email protected]")

[[Qonversion sharedInstance] setUserProperty:QONUserPropertyKeyEmail value:@"[email protected]"];

Qonversion.getSharedInstance().setUserProperty(QUserPropertyKey.Email, "[email protected]");

Qonversion.shared.setUserProperty(QUserPropertyKey.Email, "[email protected]")

Qonversion.getSharedInstance().setUserProperty(QUserPropertyKey.email, '[email protected]');

Qonversion.getSharedInstance().setUserProperty(UserPropertyKey.EMAIL, '[email protected]');

Qonversion.GetSharedInstance().SetUserProperty(UserPropertyKey.Email, "[email protected]");

Qonversion.getSharedInstance().setUserProperty(Qonversion.UserPropertyKey.EMAIL, '[email protected]');

The full list of the defined properties is provided below:

Name	Key	Description
Email	_q_email	User Email. It can be used for cross-platform authorization and integrations with Qonversion.
Name	_q_name	User Name
KochavaDeviceId	_q_kochava_device_id	Kochava Unique Device ID
AppsFlyerUserId	_q_appsflyer_user_id	Customer user ID. It can be used to cross-reference your in-house data with AppsFlyer attribution data.
AdjustAdId	_q_adjust_adid	Adjust Advertising ID
CustomUserId	_q_custom_user_id	Your Internal User ID. Use User ID for third-party Integrations to attribute events to existing users in other platforms.
FacebookAttribution	_q_fb_attribution	Mobile Cookie from the user's device
FirebaseAppInstanceId	_q_firebase_instance_id	The identifier for a Firebase app
AppSetId	_q_app_set_id	Unique user identifier for all the developer's applications on Android
AdvertisingId	_q_advertising_id	Unique user identifier assigned to a mobile device on iOS

Custom User Properties

Additionally, you can add custom user property. Qonversion can send them to third-party integrations as well. For example, you can add user details and use that data to send personalized emails or push notifications via Mailchimp and OneSignal integrations.

Qonversion.shared().setCustomUserProperty("liked-app", value: "yes")

[[Qonversion sharedInstance] setCustomUserProperty: @"liked-app" value: @"yes"];

Qonversion.getSharedInstance().setCustomUserProperty("liked-app", "yes");

Qonversion.shared.setCustomUserProperty("liked-app", "yes")

Qonversion.getSharedInstance().setCustomUserProperty('liked-app', 'yes');

Qonversion.getSharedInstance().setCustomUserProperty('liked-app', 'yes');

Qonversion.GetSharedInstance().SetCustomUserProperty("liked-app", "yes");

Qonversion.getSharedInstance().setCustomUserProperty('liked-app', 'yes');

You can use letters A-Za-z, numbers, and the following symbols _.:- as a property key.

To successfully set either Defined or Custom User Properties, launch Qonversion SDK first. Learn more.

Get User Properties

You can get user properties set for a current user as follows:

Qonversion.shared().userProperties({ userProperties, error in
  if let error = error {
    // Handle error
    return
  }
  
  userProperties?.properties.forEach({ userProperty in
    print("User property: ", "key: ", userProperty.key, ", value: ", userProperty.value)
  })
});

[[Qonversion sharedInstance] userProperties:^(QONUserProperties * _Nullable userProperties, NSError * _Nullable error) {
  if (error) {
    // Handle error
    return;
  }

  [userProperties.properties enumerateObjectsUsingBlock:^(QONUserProperty * _Nonnull userProperty, NSUInteger idx, BOOL * _Nonnull stop) {
    NSLog(@"User property: key: %@, value: %@", userProperty.key, userProperty.value);
  }];
}];

Qonversion.getSharedInstance().userProperties(new QonversionUserPropertiesCallback() {
    @Override
    public void onSuccess(@NonNull QUserProperties userProperties) {
        for (QUserProperty property : userProperties.getProperties()) {
            Log.d("User property", "Key: " + property.getKey() +
                    ", value: " + property.getValue());
        }
    }

    @Override
    public void onError(@NonNull QonversionError error) {
        // handle error here
    }
});

Qonversion.shared.userProperties(object : QonversionUserPropertiesCallback {
  override fun onSuccess(userProperties: QUserProperties) {
    userProperties.properties.forEach { 
      Log.d("User property", "key: ${it.key}, value: ${it.value}")
    }
  }

  override fun onError(error: QonversionError) {
    // handle error here
  }
})

try {
  QUserProperties userProperties = await Qonversion.getSharedInstance().userProperties();
  userProperties.properties.forEach((userProperty) {
    print('User property - key: ' + userProperty.key + ', value: ' + userProperty.value);
  });
} catch (e) {
  // handle error here
}

try {
  const userProperties = await Qonversion.getSharedInstance().userProperties();
  userProperties.properties.forEach(userProperty => {
    console.log('User property - key:' + userProperty.key + ', value: ' + userProperty.value);
  });
} catch (e) {
  // handle error here
}

Qonversion.GetSharedInstance().UserProperties((userProperties, error) =>
{
    if (error != null)
    {
        // Handle the error  
        Debug.LogError("Error" + error);   
    }
    else
    {
        userProperties.Properties.ForEach(userProperty => {
            Debug.Log("User property - key: " + userProperty.Key + ", value: " + userProperty.Value);
        });
    }
});

try {
  const userProperties = await Qonversion.getSharedInstance().userProperties();
  userProperties.properties.forEach(userProperty => {
    console.log('User property - key:' + userProperty.key + ', value: ' + userProperty.value);
  });
} catch (e) {
  // handle error here
}

The object returned by userProperties method contains several utility fields and methods:

const emailProperty = userProperties.getDefinedProperty(Qonversion.UserPropertyKey.EMAIL);

(Optional) Set User ID

If you want to implement cross-platform (Android, IOS, and Web) user entitlement management, please, follow the User Identity guide.

To match Qonversion revenue events to users in third-party tools, you need to set the identical user IDs in all of them:

Qonversion.shared().setUserProperty(.userID, value: "yourSideUserId")

[[Qonversion sharedInstance] setUserProperty:QNUserPropertyKeyUserID value:@"yourSideUserId"];

Qonversion.getSharedInstance().setUserProperty(QUserPropertyKey.CustomUserId, "yourSideUserID");

Qonversion.shared.setUserProperty(QUserPropertyKey.CustomUserId, "yourSideUserID")

Qonversion.getSharedInstance().setUserProperty(QUserPropertyKey.customUserId, 'yourSideUserId');

Qonversion.getSharedInstance().setUserProperty(UserPropertyKey.CUSTOM_USER_ID, 'yourSideUserId');

Qonversion.GetSharedInstance().SetUserProperty(UserPropertyKey.CustomUserId, "yourSideUserId");

Qonversion.getSharedInstance().setUserProperty(Qonversion.UserPropertyKey.CUSTOM_USER_ID, 'yourSideUserId');

The user ID improves the quality of events matching to the platforms where event attribution is not exclusively based on IDFA or GAID.

(Optional) Set IDFA (Identifier for Advertisers, iOS 14.5+ only)

On iOS 14.5+, after requesting the app tracking permission using ATT, you need to notify Qonversion if tracking is allowed and IDFA is available. This will help to have precise attribution in Adjust, AppsFlyer, Singular and other Qonversion integrations.

ATTrackingManager.requestTrackingAuthorization { status in
    switch status {
    case .authorized:
        Qonversion.shared().collectAdvertisingId()
      
    // handle other states below
    }
}

[ATTrackingManager requestTrackingAuthorizationWithCompletionHandler:^(ATTrackingManagerAuthorizationStatus status) {
    switch (status) {
        case ATTrackingManagerAuthorizationStatusAuthorized:
            [[Qonversion sharedInstance] collectAdvertisingId];
            break;
        
        // handle other states if needed
        
        default:
          break;
    }
}];

Qonversion.getSharedInstance().collectAdvertisingId();

Qonversion.getSharedInstance().collectAdvertisingId();

Qonversion.GetSharedInstance().CollectAdvertisingId();

Qonversion.getSharedInstance().collectAdvertisingId();

(Optional) Set ASID (App set ID, Android 12+ only)

On Android 12+, you can provide an App set ID to have it used in Qonversion integrations.

Add com.google.android.gms:play-services-appset as the dependency to your project and write the following code.

final AppSetIdClient client = AppSet.getClient(context);
final Task<AppSetIdInfo> task = client.getAppSetIdInfo();
task.addOnSuccessListener(info -> {
    final String id = info.getId();
    Qonversion.getSharedInstance().setUserProperty(QUserPropertyKey.AppSetId, id);
});

val client = AppSet.getClient(requireContext())
client.appSetIdInfo.addOnSuccessListener { info: AppSetIdInfo ->
    Qonversion.shared.setUserProperty(QUserPropertyKey.AppSetId, info.id)
}

Qonversion.getSharedInstance().setUserProperty(QUserPropertyKey.appSetId, appSetId);

Qonversion.getSharedInstance().setUserProperty(UserPropertyKey.APP_SET_ID, appSetId);

Qonversion.GetSharedInstance().SetUserProperty(UserPropertyKey.AppSetId, appSetId);

Qonversion.getSharedInstance().setUserProperty(Qonversion.UserPropertyKey.APP_SET_ID, appSetId);
