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
Before you start, you need to:
Create an API key
Go to the BlindPay Dashboard, select an instance and click the API Keys tab.

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