# Azure Communication Services

> Create an Azure Communication Services resource and retrieve the connection string used by the PADS4 Microsoft Teams integration.

The PADS4 Microsoft Teams integration relies on **Azure Communication Services** to join and manage Teams meetings. This guide walks you through creating the resource and retrieving the connection string that PADS4 CTRL Center needs.

## Before you begin

Make sure that you have:

* An **Azure subscription** with permission to create resources.
* Completed the [Azure Set-up](/ctrl-centre/administration/azure-set-up) app registration for the Teams integration.

## Step 1: Create a Communication Services resource

1. Sign in to the [Microsoft Azure Portal](https://portal.azure.com).
2. Go to **Azure Communication Services** and select **Create**.
3. Configure the resource:
   * **Subscription** — select your Azure subscription.
   * **Resource group** — choose an existing group or create a new one.
   * **Name** — any reference name for the resource.
   * **Geography** — choose the region closest to your users.
4. Select **Review + create**, then **Create**.

## Step 2: Retrieve the primary connection string

PADS4 CTRL Center needs the **Primary Connection String** from the resource.

1. Open the Communication Services resource you just created.
2. In the left menu, select **Keys**.
3. Copy the **Primary key connection string**.

<Warning>
  Treat the connection string like a password. Store it securely and rotate it if it may have been exposed.
</Warning>

You can now enter this value in PADS4 CTRL Center to complete the Microsoft Teams integration.
