What is API  - SSTTEK Academy


API, short for Application Programming Interface, is an interface that allows a software application or service to communicate with other applications or services. APIs enable data and functionality exchange between different software components. 

APIs are commonly used in the following ways: 

  • Data Sharing: An application can use APIs to share data with another application. For example, a weather application can use an API to share weather data with a third-party application or website. 
  • Functional Operations: An application can use APIs to utilize the functionality of another application or service. For instance, a payment processing API can be used for payment transactions, or a map API can be used to access mapping services. 

APIs typically communicate over a specific protocol or format. Common protocols include HTTP (Hypertext Transfer Protocol), REST (Representational State Transfer), SOAP (Simple Object Access Protocol), and GraphQL. 

APIs offer significant benefits to software developers and companies. For example, an app developer can easily add functionality to their application, such as map services, payment processing, or social media integration, by using ready-made APIs. This speeds up the software development process and improves resource efficiency. Similarly, a company can expand the reach of its products and services by offering them through APIs to other applications or developers, fostering collaborations and partnerships.
