API Integration and Automation refers to connecting different software applications using APIs to enable seamless data exchange and automated workflows. It allows systems to communicate in real time without manual intervention. Developers use REST or SOAP APIs to send, receive, and process data between platforms. Automation helps streamline repetitive tasks such as data synchronization, notifications, and system updates. This improves efficiency, reduces errors, and saves time in business operations. API integration is widely used in cloud services, enterprise applications, and DevOps environments. It enables scalable and flexible system interactions across multiple platforms.
