Upload your app to Meta Horizon Store

Updated: Apr 21, 2026

The Meta XR Platform Window is an in-editor tool that uploads your packaged Unreal Engine app directly to Meta Horizon Store. It handles the upload process in the background using ovr-platform-util, which downloads automatically on first use.

Prerequisites

Before uploading, ensure you have the following:

Meta XR Plugin: Installed and enabled in your Unreal Engine project.

Registered app: An app registered in the Meta Horizon Developer Dashboard⁠.

App ID and App Token: Available from the API tab of your app in the Meta Horizon Developer Dashboard⁠.

Packaged APK: A signed Android APK built from your project.

Configure your Android project settings

Sign your APK. For details, see the Signing Android projects⁠ section of the Unreal Engine documentation.

Modify the following settings in the Unreal Engine editor under Edit > Project Settings > Platforms > Android:

Android Package Name: This must match the package name registered in the Meta Horizon Developer Dashboard⁠.

Store Version: Each upload of your APK requires a unique store version number. Increment this number before each upload.

Install Location: No action required. For distribution builds, the Meta XR Plugin sets this to auto, which allows Android to choose between internal storage and SD card.

Upload using the Meta XR Platform Window

You can open the Meta XR Platform Window in two ways:

Toolbar: Select the Meta XR Tools dropdown in the toolbar, then select Meta XR Platform Window.

Plugin settings: Navigate to Edit > Project Settings > Plugins > Meta XR, then select the Launch Meta XR Platform Window button.

Configure the upload settings

In the Meta XR Platform Window, fill in the following fields:

Target Platform: Select Quest.

App ID: Enter the App ID from the API tab in the Meta Horizon Developer Dashboard⁠.

App Token: Enter the App Token from the same API tab.

Release Channel: Select the release channel for this upload.

Release Note: Enter a description of the changes in this build.

APK File Path: Browse to the location of your packaged APK file.

Debug Symbols: Enable this toggle to include debug symbols with the upload.

Symbol Directory: If debug symbols are enabled, specify the directory containing your symbol files.

Start the upload

Select Upload to begin the upload process. The tool runs ovr-platform-util in the background to transfer your build to Meta Horizon Store. You can select Cancel to stop an in-progress upload.
