Introduction
In today’s interconnected digital landscape, application programming interfaces (APIs) are essential for enabling seamless communication between systems, applications, and services. As organizations continue advancing their digital transformation, the focus has shifted from simply building functional APIs to designing interfaces that are clear, consistent, secure, and aligned with industry standards.
This course delivers a structured and practical approach to API design and development, combining foundational knowledge with real-world application. It covers key concepts such as RESTful API design, standardized resource structuring, and widely adopted specifications like OpenAPI (Swagger). Participants will gain the skills needed to design scalable, reliable, and developer-friendly APIs that meet modern development demands.
