# BigMailer - How do I link my account?

## Overview

To authenticate with BigMailer, you need:

1. **API Key** — a BigMailer API key.

This guide will show you how to create it.

### Prerequisites

* A BigMailer account. You can [sign up](https://app.bigmailer.io/console/signup) for free on the Startup plan.
* An activated account: click the activation link in the email BigMailer sends after signup. Until then, you cannot create API keys.
* The Account Administrator role. The account owner has it by default.

### Step 1: Create an API key

1. [Sign in](https://app.bigmailer.io/console/login) to the BigMailer console.
2. Open **Account** -> **API** ([API key management page](https://app.bigmailer.io/console/accounts/api)) and click **Create Key**.

3. Enter a **Name** that tells you which application uses the key.
4. Under **Brands** and **Actions**, limit the key to what your integration needs (for example `brands/list` and `brands/get`), then click **Create**.

5. Click **Copy to clipboard** to copy the API key, then click **OK**.

### Step 2: Enter your API key in the Connect UI

1. Open the form where you need to authenticate with BigMailer.
2. Enter your **API Key** in the designated field.
3. Click **Connect**.

You are now connected to BigMailer.
