Welcome
Teams SDK is a suite of packages for building agents and applications on Microsoft Teams. It handles authentication, event routing, and Teams-specific plumbing so you can focus on your app's logic.
Get started
The fastest path is the Teams Developer CLI (in Preview):
- Register your app install the CLI, register a bot, sideload into Teams.
- Build your first bot write a message handler in TypeScript, C#, or Python.
If you'd rather have your AI coding assistant do the work, install the teams-dev skill and ask it to "create a Teams bot".
What you can build
Teams SDK has you covered for AI-powered agents, message extensions, embedded web apps, Adaptive Cards, dialogs, Microsoft Graph integrations, and more across TypeScript, C#, and Python.
- Why an SDK? what the SDK handles for you
