API Design that Matters

An Application Programming Interface (API) is one of the most talked-about technologies in the eCommerce industry. Many merchants try to measure an API's worth and understand its business value, yet they often have only a limited grasp of the technology behind it.

Broadly speaking, an API is a set of rules that allows different software systems to connect and communicate with each other. It facilitates interactions between applications, different code modules or backend IT systems, and establishes data sharing between components.

An API itself isn't a new concept, but as computer systems have become more complex, the need for this technology has grown rapidly. Its prevalence across the Web is now clear, as vendors use the Internet as the main network through which they integrate their systems with various shopping platforms.

Developing an Application Programming Interface is not a simple task and must be designed with both programmers and target users in mind. When it comes to full-functioned API design, there are several key qualities that every API should have. To make your API perform effectively, it must satisfy certain functional and nonfunctional requirements. These may vary depending on the context, but most commonly include:

  • Scalability. The ability to handle rapid increases in traffic load.
  • Security. Protection of users and data from attacks.
  • Reliability. Strong enough to minimize downtime.
  • Usability. Easy for developers to use and implement.
  • Testability. Allows programmers to test and verify functionality.
