What is an API?

An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. Think of it as a waiter in a restaurant: you (the client) place an order, the waiter (the API) takes it to the kitchen (the server), and returns with your response. APIs are what make modern software ecosystems work — from payment processing and map integrations to social logins and shipping tracking.

How APIs Work

An application sends a request to an API endpoint, the server processes it, and returns a structured response (typically in JSON or XML format). For example, a weather app sends a request to a meteorology API and displays the returned forecast data in its own interface.

REST vs SOAP APIs

• REST API: A lightweight, flexible API architecture that operates over HTTP and transfers data in JSON format. The standard for modern web and mobile applications.
• SOAP API: An XML-based protocol with stricter standards. Commonly used in enterprise and financial systems where security and formal contracts are required.

Why API Integration Matters

API integrations allow your e-commerce platform to automatically sync with your accounting software, shipping carriers, and marketplaces — eliminating manual data entry, reducing human error, and significantly improving operational efficiency. Teknobursa builds robust API integrations as part of all our enterprise software and e-commerce projects.
