The acronym 'API' stands a very important part of the software development world, despite a complete lack of recognition of the wider world. The letter stands for Application Programming Interface and without the API, a wide range of integrated digital services will be unavailable – from posting pictures on social networking sites to sending emails via SMS.
Implementation of the API and other ways of Application Integration is what allows applications, libraries, and operating systems to understand each other and interact, changing technology and software from complex niche to be widely accessible, multi-purpose consumer services.
API works in a manner similar to the user interface; provides an abstract interface to the functional interaction between the different components of different software systems. There are several different categories of APIs, tailored to the specific or general use. Two main categories are:
• Public API – This is the most widespread form of API, the effective part of a programming language that allows for functional interactivity between different programs. Examples include the Standard Template Library in C ++ or Java API.
• Special API – this is the API that is designed for a specific problem or goal. Examples include the Google Maps API, which allows developers to access Google Maps data and templates for building visualization tools such as online travel planner or pedometres, or API SMS for text message marketing campaigns.
