Workday Extend gives developers a native way to extend Workday’s HCM and Finance system instead of relying on risky workarounds or shadow IT. This course walks through the complete application lifecycle – modeling business objects, designing pages, automating business processes, integrating external systems, and applying governance. You will practice inside a live sandbox tenant, complete structured labs, and finish with a capstone project that reflects what employers expect from a certified developer in 2026, including the platform’s newer AI-assisted development capabilities.
