# Radar - How do I link my account?

## Overview

To authenticate with Radar, you need:

1. **API Key** - A Secret or Publishable key from your Radar dashboard.

This guide will show you where to find it.

### Prerequisites

* A Radar account. Radar does not offer a free tier, and every plan starts with a quote: [contact Radar](https://radar.com/contact) to get access.

### Step 1: Copy your API key

1. Log in to the [Radar dashboard](https://dashboard.radar.com/login).
2. Open the [Settings](https://dashboard.radar.com/settings) page.
3. Copy the key you need. Use a Live key for production and a Test key for testing and non-production environments:
   * **Live Secret** or **Test Secret** key (starts with `prj_live_sk_` or `prj_test_sk_`). Endpoints with the `Secret` authentication level, such as listing users, are only safe to call server-side with a Secret key.
   * **Live Publishable** or **Test Publishable** key (starts with `prj_live_pk_` or `prj_test_pk_`). Use it for endpoints with the `Publishable` authentication level.

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

1. Open the form where you need to authenticate with Radar.
2. Paste your key in the **API Key** field.
3. Submit the form, and you should be successfully authenticated.

You are now connected to Radar.
