# Jira Data Center (API Key) - How do I link my account?

# Overview

To authenticate with Jira Data Center (API Key), you will need:

1. **Instance Base Url** - The root URL of your Jira Data Center instance.
2. **API Key** - A key that grants Nango permission to interact with your Jira Data Center instance’s APIs, resources, and services.

This guide will walk you through generating an API Key and finding your Instance Base URL within Jira Data Center.

### Instructions:

#### Step 1: Finding Your Instance Base Url

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

Once you have your **Instance Base Url** and **API Key**:

1. Open the form where you need to authenticate with Jira Data Center (API Key).
2. Enter your **Instance Base Url** and **API Key** in their designated fields.
3. Submit the form, and you should be successfully authenticated.
