Generating API Keys: A Complete Overview

What Is an API Key?

An API key is a unique identifier used to authenticate requests made to an application programming interface (API). Essentially, it acts as a security credential that helps systems verify who is making a request and whether that request is authorized. API keys are commonly used in software integrations, allowing applications to communicate securely — for instance, between a merchant portal and an e-commerce platform such as WooCommerce, OpenCart, or custom payment gateways.

API keys enable businesses to:

• Authorize access to specific system functions.

• Track and control API usage and data exchange.

• Secure connections between integrated systems.

• Simplify setup for developers and merchants connecting multiple tools.

The key is tied to the user’s EPI (Electronic Payment Interface) and enables third-party software, like shopping cart plugins, to connect to the payment platform.
