# Altoviz - How do I link my account?

## Overview

To authenticate with Altoviz, you need:

1. **API key** — a key you create in the settings of your Altoviz account.

This guide will show you how to create one.

### Prerequisites

* An Altoviz account. If you don't have one, register from the [Altoviz sign-in page](https://app.altoviz.com) and finish the company setup. Altoviz has a free plan, and the API is available on it.

### Step 1: Create an API key

1. Sign in to the [Altoviz app](https://app.altoviz.com).
2. In the left menu, click **Paramètres** (Settings). Under **Avancé** (Advanced), click **Clés d'API** (API keys).

3. Click **Nouvelle clé d'API** (New API key) and enter a label, for example `nango`.
4. Choose the access the key gets for each area (**Ventes**, **Achats**, **Notes de frais**, **Trésorerie**, **Comptabilité**): no access, read-only (**Lecture seule**), or read and write. Give it only the access your integration needs.
5. Click **Créer** (Create).

6. Copy the API key with the copy button before you close the dialog. Altoviz only shows the full key once.

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

1. Open the form where you need to authenticate with Altoviz.
2. Enter your API key in the **API Key** field.
3. Submit the form, and you should be successfully authenticated.

You are now connected to Altoviz.
