# Checkout.com - Sandbox - How do I link my account?

## Overview

To authenticate with Checkout, you will need:

1. **Client ID** - A unique identifier for your application on Checkout.
2. **Client Secret** - A key that grants full access to all your application and configurations.

This guide will walk you through generating the Client ID and Client Secret within Checkout.

## Prerequisites:

* You should have a registered test account with Checkout. Create one on [Checkout Getting Started page](https://checkout.com/).
* Permission to generate **API Keys**.

#### Step 1: Creating an Access Key Pair (Client ID and Client Secret)

1. From your Checkout sandbox dashboard, click on the **Developer** icon at the top right corner of the screen.
