# PRTG Classic - How do I link my account?

## Overview

To authenticate with PRTG's classic HTTP API, you will need:

1. **Instance Host** - The host of your PRTG instance.
2. **API Key** - A key that grants Nango permission to access the classic PRTG HTTP API.

This guide will walk you through finding both values in PRTG.

<Note>This integration is for the classic PRTG HTTP API with `apitoken` query authentication, not PRTG API v2.</Note>

### Prerequisites:

* You must have access to a PRTG user account that can create API keys.

### Instructions:

#### Step 1: Finding Your Instance Host

1. Log in to your PRTG instance.
2. Copy the host from your browser address bar, for example `monitor.example.com`.

#### Step 2: Finding Your API Key

1. In PRTG, go to **Setup** -> **Account Settings** -> **API Keys**.
2. Click **+** and select **Add API Key**.

3. Fill in the key details, set the required access level, and copy the generated API key.

#### Step 3: Enter credentials in the Connect UI

Once you have your **Instance Host** and **API Key**:

1. Open the form where you need to authenticate with PRTG.
2. Enter your **Instance Host** and **API Key** in their designated fields.
3. Submit the form, and you should be successfully authenticated.
