# ASIN Data API - How do I link my account?

## Overview

To authenticate with ASIN Data API, you need:

1. **API Key** - the API key of your ASIN Data API account.

This guide will show you how to find it.

### Prerequisites

* An ASIN Data API account. If you don't have one, [sign up for free](https://app.asindataapi.com/signup) and click the verification link in the email ASIN Data API sends you.

### Step 1: Copy your API key

Each ASIN Data API account has one API key, created automatically.

1. Log in to the [ASIN Data API dashboard](https://app.asindataapi.com/login). You land on the **API Playground**.
2. Your API key is shown next to **API Key** at the top of the page. Click the copy icon next to it.
