Create custom messaging extensions for Microsoft Teams

Learn how to create messaging extensions for Microsoft Teams apps, including action-based, search-based, and URL unfurling.

I work with Microsoft Learning to publish & maintain multiple self-paced learning modules related to Microsoft 365. These modules are primarily used as self-paced study resources for developers preparing to take the MS-600 exam , the only prerequisite to achieve the Microsoft 365 Certified: Teams Application Developer Associate certification. This is one of those modules.

Users can interact with your Microsoft Teams apps though buttons and forms in the Microsoft Teams client. Messaging extensions enable users to execute search queries or trigger actions in external systems. The results of these actions are sent from your custom web service to the Microsoft Teams client as embedded web pages or richly formatted cards.

In this module, you’ll learn how to create different types of messaging extensions in a custom Microsoft Teams app.
