# CallerAPI - How do I link my account?

## Overview

To authenticate with CallerAPI, you need:

1. **API Key** — the API key from your CallerAPI dashboard.

This guide will show you how to find it.

### Prerequisites

* A CallerAPI account. CallerAPI uses Google sign-in.

### Step 1: Copy your API key

1. Go to the [CallerAPI dashboard](https://callerapi.com/dashboard) and sign in with Google.
2. If a **Special Offer** pop-up opens, close it with the **X** button in its top-right corner.

3. In the **API key** card on the **Dashboard**, click **Copy key**. Click **Show key** if you want to see it first.

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

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