## What it is

An API key is a unique identifier used to authenticate your requests to the BlindPay API.

## How it works

An API key authenticates you to a **single instance** — a key created for instance X will not work for instance Y. You can only create an API key through the BlindPay Instance Dashboard.

## Prerequisites

## Create an API key

Go to the [BlindPay Dashboard](https://app.blindpay.com/){target="\_blank"}, select an instance and click the `API Keys` tab.

Done. Authenticate all requests by passing the header `Authorization: Bearer YOUR_API_KEY`.
