So, now that you know what an API is, why is it so important? Well, an API particularly comes into play when companies or organizations invest in software to help run their business.

For example, there are many companies that use Google APIs to integrate into their products, such as Google Analytics or Google Maps, among others.

Developers use application programming interfaces to hide complexity, organize code, design reusable components, and connect different systems, applications, or services.

Provide sample responses in your API documentation so the user has a solid idea if it is behaving as expected or not. Use consistent naming conventions.

While the concept of an "API restriction" may not sound dramatic, this latest change has users once again worried about Twitter's future.
