# Microsoft Teams

Send messages to Teams channels and users, schedule online meetings, and manage team membership — all without leaving your automation flow. Uses Microsoft Graph API with OAuth 2.0 client credentials.

## Authentication

**Auth type:** OAuth 2.0 (client credentials)

Register an app in [Azure Portal](https://portal.azure.com) → **App registrations**. Grant it the following **application permissions** (not delegated): `Chat.ReadWrite`, `ChannelMessage.Send`, `OnlineMeetings.ReadWrite`, `Team.ReadBasic.All`, `TeamMember.ReadWrite.All`. Then grant admin consent.

| Credential        | Description                                        |
| ----------------- | -------------------------------------------------- |
| **Tenant ID**     | Your Microsoft Entra (AAD) tenant ID               |
| **Client ID**     | The application (client) ID from App registrations |
| **Client Secret** | A client secret value — not the secret ID          |

## Triggers
