# PDF Vector - How do I link my account?

## Overview

To authenticate with PDF Vector, you need:

1. **API Key** — an API key from your PDF Vector instance settings.

This guide will show you how to get it.

### Prerequisites

* A PDF Vector account. You can [sign up for free](https://app.pdfvector.com/auth/sign-up), no credit card required.

### Step 1: Create an API key

1. Log in to the [PDF Vector dashboard](https://app.pdfvector.com/auth/sign-in).
2. In the left sidebar, click **Instances**, then click **General Instance** (`global.pdfvector.com`).
3. Open the **Settings** tab and, in the **API Keys** section, click **Create Key**.

4. Enter a name for the key (for example, `nango`) and click **Create**.

5. The new key appears in the **API Keys** list. Click the copy button next to it to copy the key.

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

1. Open the form where you need to authenticate with PDF Vector.
2. Enter your key in the **API Key** field.
3. Submit the form. The connection is saved without checking the key: if the key is wrong, the first API request returns an authentication error.

You are now connected to PDF Vector.
