Code-based Experiences & Content Cards - API reference

This document lists the public APIs available in the Messaging extension for implementing code-based experiences and content cards.

getPropositionsForSurfaces

The getPropositionsForSurfaces API retrieves the previously fetched propositions from the SDK's in-memory propositions cache for the provided surfaces. The completion handler is invoked with the decision propositions corresponding to the given surfaces or AEPError, if it occurs.

If a requested surface was not previously cached prior to calling getPropositionsForSurfaces (using the updatePropositionsForSurfaces API), no propositions will be returned for that surface.

public static void getPropositionsForSurfaces(@NonNull final List<Surface> surfaces, @NonNull final AdobeCallback<Map<Surface, List<Proposition>>> callback)

surfaces is a list of surfaces for which propositions are requested.
callback call method is invoked with propositions map of type Map<Surface, List<Proposition>>. If the callback is an instance of AdobeCallbackWithError, and if the operation times out or an error occurs in retrieving propositions, the fail method is invoked with the appropriate AdobeError.

updatePropositionsForSurfaces

The updatePropositionsForSurfaces API dispatches an event for the Edge network extension to fetch personalization decisions from the AJO campaigns for the provided surfaces array. The returned decision propositions are cached in-memory by the Messaging extension.

To retrieve previously cached decision propositions, use getPropositionsForSurfaces API.

Copied to your clipboard
public static void updatePropositionsForSurfaces(@NonNull final List<Surface> surfaces, @Nullable final AdobeCallback<Boolean> callback)

surfaces is a list of surfaces for which propositions need updating.
callback call method is invoked with true if a network response was returned and successfully processed, false otherwise

Example

Kotlin

val surface1 = Surface("myActivity#button")
val surface2 = Surface("myActivityAttributes")
val surfaces = listOf(surface1, surface2)

Messaging.updatePropositionsForSurfaces(surfaces) { success ->

surfaces is an array of surfaces for which propositions need updating.
completion is invoked with true if a network response was returned and successfully processed, false otherwise

Example
