# Private API (Generic) - How do I link my account?

# Overview

To authenticate with Private API (Generic), you need one key piece of information:

1. **API Key** - The key that the proxy injects into your upstream API requests.

How the key is presented (header vs query param, its name, and any prefix like `Bearer` or `Api-Key`) is configured on the integration by the team that set it up, not by the end user.

This guide will walk you through setting up a connection with Private API (Generic).

## Step 1: Get your API Key

Obtain your API key from your API provider.

## Step 2: Enter credentials in the Connect UI

Once you have your **API Key**:

1. Open the form where you need to authenticate with Private API (Generic).
2. Enter your **API Key** in the API key field (its label may be customized for the integration).
3. Submit the form, and you should be successfully authenticated.

You are now connected to Private API (Generic).
