# Everflow - How do I link my account?

# Overview

To authenticate with Everflow, you need:

1. **API Key** — A key that grants Nango access to the Everflow API on your behalf.
2. **Subdomain** — `api` for standard accounts, or `api-eu` if your account is EU-hosted.

This guide will walk you through generating your API key and finding your subdomain in Everflow.

### Prerequisites

* An active Everflow account with administrator access.

### Step 1: Generate your API key

1. Log in to your Everflow account.
2. Navigate to **Control Center** in the top menu, then select **Security**.
3. Click the **API Keys** tab.
4. Click **+ API Key**.
5. Fill in the required details:
   * **Key name** — a descriptive label (e.g. "Nango integration")
   * **Who will use it** — the employee or service that owns this key
   * **What it can access** — select the API permissions this key needs
6. Copy the generated API key immediately — it is only shown once and cannot be retrieved later.

### Step 2: Find your subdomain

Your subdomain is `api` for standard accounts. If your Everflow account is EU-hosted, use `api-eu` instead.

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

Once you have your API key and subdomain:

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