What role does the API Interface serve in application integration?

The API Interface plays a crucial role in application integration by acting as a software intermediary that enables communication between two applications. This functionality is essential as it allows different systems, which may be built on diverse technologies or platforms, to interact and exchange data seamlessly.

Through the API Interface, one application can make requests for data or services from another, and the receiving application can respond accordingly. This interaction is typically standardized using protocols or formats such as REST, SOAP, JSON, or XML, which fosters compatibility and simplifies the exchange process.

By providing this intermediary capability, the API Interface helps to decouple systems and promotes modular architecture in application design. This leads to greater flexibility in integrating new services, components, or third-party applications, facilitating easier maintenance and scalability.
