# Quick Start

{% hint style="warning" %}
**You must first sign up for a Qvalia account, and contact Sales or Support to get access and API setup!**
{% endhint %}

### Get your API keys

Your API requests are authenticated using API keys. Any request that doesn't include an API key will return an `401` error.

**You will get your API key from Qvalia support, or the onboarding team!**

### Review the API Documentation

{% content-ref url="api-documentation/apis" %}
[apis](https://api.qvalia.io/api-documentation/apis)
{% endcontent-ref %}

### Make your first request

To make your first request, send an authenticated request to the `/invoices` endpoint. This will create an `invoice`.

### Create outgoing invoice
