Apps for Microsoft Teams
You can extend Microsoft Teams by developing an app that provides content and services. A single app can provide one or more capabilities. Deciding which capabilities to offer depends on what you want to do. Apps are available in the Teams store, and can be custom built by you for distribution through the store or directly to your users.
Microsoft Teams apps are web apps, you can use any web-programming technology and can host them on any hosting platform.
An app in Teams consists of the following parts:
A Microsoft Teams app is defined by its manifest (a JSON file). Place the manifest and two icons in a .zip file, and you have an app package that you can install into Teams or publish through AppSource. (For details, see Create the package for your Microsoft Teams app.)
Teams App Studio is a new tool that will help you to configure your application. It also contains a React control library and configurable samples for cards. See Getting started with Teams App Studio.
Once an app has been created and has been a manifest it can be uploaded into a teams channel that you have rights to. See Upload your custom app in Microsoft Teams.
The final step of creating an app is publication. For more information see: Publish your app.
