API Key Authorization is a method used to secure access to an API (Application Programming Interface) by requiring clients to include a unique API key when making requests. This key is typically a long alphanumeric string that is issued to the client by the API provider. API keys serve as a form of authentication and authorization, allowing the API provider to identify and control access to their API.

The API provider generates a unique API key for each client or application that needs access to their API. This key is often associated with specific usage limits or permissions.

Clients must include their API key in the headers or query parameters of their API requests. This key is used to identify the client making the request.

API Key is key-value pair based authorization where the key is **`Authorization`** and the value is a one-time string generated from the application while enabling the API for a defined set of actions with roles and privileges.

There are various applications whose API Keys are static. It is a one-time activity to enable those keys, keep them secret, and use them for API Authorization.
