What Is An API | Vpedia - Empowering knowledge sharing

An Application Programming Interface (API) is a connection between computers or between computer programs, offering a service to other pieces of software, and is a type of software interface that allows different systems to communicate with each other. The use of APIs has become increasingly popular with the rise of microservices architecture and cloud computing. APIs are used to enable communication between different systems. GraphQL and other query languages are used to enable more efficient and flexible data exchange. API gateways are used to manage and secure API traffic. API security measures such as OAuth and JWT are used to protect against API-based attacks.
