# Microsoft Dynamics 365 Finance and Operations - How do I link my account?

# Overview

To connect Microsoft Dynamics 365 Finance and Operations in Nango, you need to provide:

1. **Tenant ID** — The unique identifier for your organization that uses Microsoft services.
2. **Environment URL** — The domain of your Finance and Operations environment.

This guide walks you through finding both values, then authorizing through Microsoft Entra ID.

### Prerequisites

* You must have an active Microsoft Entra ID (Azure AD) account with access to a Finance and Operations environment.

### Step 1: Finding your Tenant ID

1. Your Tenant ID can be found in the **Tenant ID** field on the [Overview page](https://aad.portal.azure.com/#view/Microsoft_AAD_IAM/ActiveDirectoryMenuBlade/~/Overview) within your Azure account.

### Step 2: Finding your Environment URL

Sign in to your Finance and Operations environment, then copy its domain from the browser's address bar — everything after `https://` and before the first `/` (for example, `mycompany.operations.dynamics.com`).

### Step 3: Authorize the connection

1. Open the form where you need to authenticate with Microsoft Dynamics 365 Finance and Operations.
2. Enter the **Tenant ID** and **Environment URL** in their designated fields.
3. Submit the form, then log in with your Microsoft account and grant the requested permissions.
