Guide to Launching Child Power Apps in Windows Version: Best Practices

For developers and businesses using Microsoft’s Power Apps, it’s often essential to understand how to launch one app from another, especially in the Windows environment. This guide will provide an in-depth look at how to initiate a child Power App from a parent Power App in the Windows version of Power Apps. By the end, you’ll be proficient in this vital functionality, enhancing both user experience and app integration.

Why Launch a Child Power App?

Imagine a situation where you have a primary or ‘master’ application and need to initiate a secondary or ‘child’ application. This structure is often used to distribute different functionalities or for performance optimization, ensuring a streamlined user experience.

Understanding the ‘Launch’ Formula

The core formula for initiating a child Power App from a master one is ‘Launch’. You can delve deeper into its intricacies and examples in the official Microsoft documentation.

Steps to Launch a Child Power App

When working with the master Power App:

  • Utilize the following syntax to launch the desired child Power App:

Remember to replace app_id with the specific ID of the child Power App. You can easily locate this ID by navigating to the Maker Portal, choosing the target app, and accessing its ‘Details’ from the menu.

Deep Linking to Specific Screens

Power Apps offers the ability to deep link directly to certain screens or pages within the child app. Here’s an example of how to pass a specific parameter, like ‘recordID’:

    Launch("ms-apps:///providers/Microsoft.PowerApps/apps/app_id", {recordID:6545})

Once initiated, utilize the formula within the ‘OnStart’ of the child app to identify the ID and direct the user to the specific screen. Learn more about this deep linking technique in the official Microsoft guide.

If you’re running the master app in a browser, selecting the ‘Open Child App’ button will prompt a dialog. Opting for the ‘Open Power Apps’ button will then initiate the app in the Windows version of Power Apps.


Launching child Power Apps from a primary app in the Windows version is a crucial functionality that can significantly boost your app’s efficiency and user experience.
