Signal

The Signal extension allows marketers to send a "signal" to their apps through the Adobe Experience Platform Mobile SDKs. This signal might tell the Mobile SDKs or the apps to complete tasks, such as send PII-labeled data, to trigger a postback to a third-party ad-network and open an app deep link or URL. To ensure that signals are sent or are activated, the marketers need to configure triggers and traits in the Data Collection UI.

The Signal extension allows you to send postbacks to third-party endpoints and open URLs, such as web URLs or application deep links, when using rules actions in the Data Collection UI.

To send PII data to external destinations, the PII action can trigger the Rules Engine when certain triggers and traits match. When setting a rule, you can also set the PII action for a Signal event. The collectPii API can then be used to trigger the rule and send the PII data to a remote server.

To get started with Signal extension, complete the following steps:

Add the Signal extension to your app.
Define the necessary rules in the Data Collection UI.
(Optional) When using Send PII actions in the Data Collection UI, implement the APIs to collect PII data and send it to the configured third party destination.

For more information about creating and configuring a rule in the Data Collection UI, see Rules.

Add the Signal extension to your app

Android

Add the Signal extension and its dependency, the Mobile Core extension to your project using the app's Gradle file.

Kotlin

implementation("com.adobe.marketing.mobile:core")
implementation("com.adobe.marketing.mobile:signal")
Copied to your clipboard
implementation(platform("com.adobe.marketing.mobile:sdk-bom:3.+"))

Register the Signal extension

The MobileCore.registerExtensions() API can be used to register the Signal extension with the Mobile Core extension. This API allows the extension to send and receive events to and from the Mobile SDK.

To register the Signal extension, use the following code sample:

Android

After calling the setApplication() method in the onCreate() method, register the Signal extension.

Java

public class MobileApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        MobileCore.setApplication(this);

        List<Class<? extends Extension>> extensions = Arrays.asList(Signal.EXTENSION, ...);
        MobileCore.registerExtensions(extensions, o -> {
            // Any other post registration processing
        });
    }
}
Copied to your clipboard
public class MobileApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        MobileCore.setApplication(this);

        List<Class<? extends Extension>> extensions = Arrays.asList(Signal.EXTENSION, ...);
        MobileCore.registerExtensions(extensions, o -> {
            // Any other post registration processing
        });
    }
}

iOS

After calling the setApplication() method in the onCreate() method, register the Signal extension.

Java

public class MobileApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        MobileCore.setApplication(this);

        List<Class<? extends Extension>> extensions = Arrays.asList(Signal.EXTENSION, ...);
        MobileCore.registerExtensions(extensions, o -> {
            // Any other post registration processing
        });
    }
}
Copied to your clipboard
public class MobileApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        MobileCore.setApplication(this);

        List<Class<? extends Extension>> extensions = Arrays.asList(Signal.EXTENSION, ...);
        MobileCore.registerExtensions(extensions, o -> {
            // Any other post registration processing
        });
    }
}

In your app's application:didFinishLaunchingWithOptions, register the Signal extension with Mobile Core:

Swift

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
     MobileCore.registerExtensions([Signal.self, ...]) {
       MobileCore.configureWith(appId: "yourAppId")
       // Any other post registration processing
     }
     return true;
}
Copied to your clipboard
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
     MobileCore.registerExtensions([Signal.self, ...]) {
       MobileCore.configureWith(appId: "yourAppId")
       // Any other post registration processing
     }
     return true;
}

Objective-C

    [AEPMobileCore registerExtensions:@[AEPMobileSignal.class, ...] completion:^{
        [AEPMobileCore configureWithAppId: @"yourAppId"];
        // Any other post registration processing
    }];
    return YES;
 }
Copied to your clipboard
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [AEPMobileCore registerExtensions:@[AEPMobileSignal.class, ...] completion:^{
        [AEPMobileCore configureWithAppId: @"yourAppId"];

        });
    }
}
Copied to your clipboard
public class MobileApp extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        MobileCore.setApplication(this);

       // Any other post registration processing
     }
     return true;
}
Copied to your clipboard
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
     MobileCore.registerExtensions([Signal.self, ...]) {
       MobileCore.configureWith(appId: "yourAppId")
       // Any other post registration processing
     }
     return true;
}

Objective-C

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [AEPMobileCore registerExtensions:@[AEPMobileSignal.class, ...] completion:^{
        [AEPMobileCore configureWithAppId: @"yourAppId"];
        // Any other post registration processing
    }];
    return YES;
 }
Copied to your clipboard
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    [AEPMobileCore registerExtensions:@[AEPMobileSignal.class, ...] completion:^{
        [AEPMobileCore configureWithAppId: @"yourAppId"];
        // Any other post registration processing
    }];
    return YES;
 }

Implement the Mobile SDK to send PII data to external destinations

To send PII data to external destinations, the PII action can trigger the Rules Engine when the configured triggers and traits match. When creating a rule, you can set the PII action for a Signal event, so that collectPii can trigger the rule and send the PII data.

For more information about collectPii and its usage, see collectPii.

For more information about how to configure the Signal postbacks in the Data Collection UI, see Signal extension and Rules Engine integration.
