The text discusses headless API architecture, its benefits, and implementation guide. Headless API architecture separates the frontend UI from the backend services, creating a more flexible foundation for building robust, adaptable systems. This separation delivers several key benefits, including unparalleled flexibility, enhanced scalability, improved performance, omnichannel delivery, and future-proofing. The text also provides a step-by-step implementation process, security best practices, performance optimization strategies, testing strategies, and a decision framework for adopting headless architecture.
