The technology that enables seamless integration of applications and data is known as Application Programming Interfaces (APIs). APIs allow different software systems to communicate with each other, facilitating data transfer and functionality sharing. With the rise of cloud computing, APIs have become crucial for connecting various services and platforms, leading to more efficient workflows and innovation. Moreover, they support interoperability, enabling businesses to leverage existing systems while adopting new technologies. The effective use of APIs can enhance user experiences and streamline operations across diverse applications.
