# Set Up Mobile In-App Campaigns

Before creating a Mobile In-App message, prepare the audience and decisioning objects that determine which customers can receive the campaign. This page covers the three Engage Studio setup tasks for campaign owners. App and SDK integration prerequisites are covered in the [Mobile In-App SDK Integration Prerequisites](/products/marketing-cloud/engage-studio/channels/mobile-inapp/sdk-integration-prerequisites) guide.

Beta
Mobile In-App Messaging is currently in beta. Message types, campaign settings, and delivery behavior may change before general availability.

## Set Up the Campaign Decisioning Objects

Complete these steps in Audience Studio and Engage Studio:

1. Create or select a **Parent Segment** that defines the eligible customers. Confirm that the Parent Segment contains the intended test customer.
2. Create a **Realtime Personalization** entry. Confirm that the entry is available for the campaign configuration.

1. Create a **Personalization Section** that stores the Mobile In-App message payload. Confirm that the Section is linked to the Realtime Personalization entry.
