# Apple Business Manager - How do I link my account?

# Overview

To authenticate with Apple Business Manager, you will need:

1. **Client ID** – Returned when you upload your public key in Apple Business Manager.
2. **Key ID** – Returned when you upload your public key in Apple Business Manager.
3. **Private Key** – The EC private key (PEM format) you generate to sign the client assertion JWT.

This guide will walk you through generating your **Private Key** and finding your **Client ID** and **Key ID** in Apple Business Manager.

### Prerequisites:

* An [Apple Business Manager](https://business.apple.com) account with the **Administrator** role.

### Instructions:

#### Step 1: Create an API account and generate a private key

Apple Business Manager authenticates using a P-256 elliptic curve private key that you generate — it is never stored by Apple.

1. Sign in to **Apple Business Manager** as a user with the **Administrator** role.
2. Select your name at the bottom of the sidebar, then select **Preferences** → **API**.

3. Click **Create API Account**.

4. Enter an account label, click **Create**, then click **Generate Private Key** and save the file.

The `.pem` file automatically downloads to your browser's download location. This key is used to sign JWTs for authentication.

#### Step 2: Note your credentials

After generating the private key, Apple Business Manager displays your API account details. Select **Manage** to view:

* **Client ID** – A unique identifier for your API account, used in JWT claims.
* **Key ID** – The identifier for the key pair, used in the JWT header.

Keep these values available for the next step.

#### Step 3: Enter credentials in Nango

Once you have your **Client ID**, **Key ID**, and **Private Key**:

1. Open the form where you need to authenticate with Apple Business Manager.
2. Enter your **Client ID**, **Key ID**, and **Private Key** in their respective fields.
3. Submit the form to complete authentication.
