API application programming interface . Providing convenient coding and development technologies and interaction web.

API – Definition

Faced with data import or synchronization problems, developers had to look for a way to make the software communicate with each other. The API or programming interface is one of the solutions invented. Here is an overview of this technology dear to programmers.

API or application programming interface

Detailed in computer science courses, an API refers to an application programming interface. It addresses specific issues for specific end users. Whether for the general public or a closed circle, the API allows software to communicate and interact with each other. They exchange data and their services even become complementary. For the user, an API is also defined as a set of functionalities offering the possibility of formulating specific requests.

How these interfaces work

An API aims to provide access to data or functionality that is located remotely. The user does not have the application in his terminal, but the programming interface takes him to the correct command. This communication becomes possible thanks to a universal computer language. It allows you to request actions or have files. The system is based on a centralized server.

Different configurations are possible

Application programming interfaces form a large family with many ramifications. That said, there are 3 categories that separate them. The open API is accessible to anyone who knows how to do it. Then there is the partner API which requests a license from the publisher or specific rights. A 100% private form of the application programming interface is also commonly used in businesses for internal needs.

Reasons to develop more APIs

An API allows a business to have more functionality on its website or dedicated application. This interface can also be used internally, especially for companies that manage a large database with different file formats. In both cases, third parties access the content and orders. Developers allow software to become complementary.

Technology already used on a daily basis

Internet advertising campaigns require an API. Well-known example, Google AdWords uses this interface for targeted ads. Operating systems such as Windows, Mac OS or application servers like Apache will also commonly use this communication between software. Then, there are SaaS Cloud solutions from Salesforce or Microsoft Office 365. It is thanks to an API that Maps type maps can be integrated into third-party sites.

Two variations of this invention

Simple Object Access Protocol or SOAP is the oldest form of API. It allows data transmission, but tends to give way to a more recent configuration. REST application programming interfaces are popular with software publishers for their flexibility. The Representational State Transfer category emerged thanks to greater openness. Even more relevant, Restful APIs have also taken up the torch for some time.
