The Microsoft Teams Developer Platform allows you to integrate your app into Microsoft Teams. You can do this via Tabs that directly surface your web experience, Bots that surface your experience in chat, and Connectors that send your notifications into channels. Please read the tag info (README) for guidance on how to increase the chance that you'll get a high quality answer to your questions.
The Microsoft Teams Developer Platform offers several ways to integrate with Microsoft Teams:
Tabs allow team members to access your service on a dedicated canvas within a channel. This lets them work directly with the tools and data you provide, in the channel’s context, and to have conversations about them. A tab consists of a package (manifest), a “configuration page” and a “content page”. These pages must include the Microsoft Teams JavaScript library, which has APIs to assist integration into the Microsoft Teams web and desktop clients.
Bots allow your customers to interact with your service through conversation, via the Microsoft Bot Framework, the same framework used to build apps across Microsoft platforms including Skype and Office 365 mail.
Connectors help bring useful information and rich content from your services right into channels in Microsoft Teams and enable collaborating team members to have engaging conversations around them.
