This SDK will be deprecated, and will not receive further updates.

Bot Builder Microsoft Teams Extensions

Build status

The Microsoft Bot Builder SDK Teams Extensions allow you to build bots for Microsoft Teams quickly and easily. Review the documentation to get started!

Note that the Bot Builder Extensions does NOT yet work with Bot Framework SDK 4.x. It currently only works with Bot Framework SDK 3.x.

This SDK allows you to easily...

  • Fetch a list of channels in a team
  • Fetch profile info about all members of a team
  • Fetch tenant-id from an incoming message to bot
  • Create 1:1 chat with a specific user
  • Mention a specific user
  • Consume various events like channel-created, team-renamed, etc.
  • Accept messages only from specific tenants
  • Write Compose Extensions
  • and more!


If you are building your bot in .NET, simply grab the Microsoft.Bot.Connector.Teams nuget.

If you are using Node, grab the botbuilder-teams NPM instead.

Get started quickly with our samples:

  • Sample bot C#
  • Sample bot Node
