About

The Workday Studio Developer Certification validates professional-level expertise in designing, building, and maintaining Workday integrations using Workday Studio. Launched as Workday's official credential for integration developers, this certification is restricted to Workday-employed, customer-employed, or certified-partner candidates. Certification confirms mastery of Workday integration architecture, REST and SOAP API consumption, XSLT/XPath transformation, MVEL scripting, event-based integration (EIB), and cloud-based data connectors. Roles certified at this level are capable of leading mid-to-large integration projects and mentoring junior developers.

Recommended courses at Integration & Development · Professional

Course-selection rule: Workday maintains tight control over official training. Most hands-on Studio training is employer-provided through Workday University; public courses (LinkedIn Learning, Udemy) offer foundational knowledge but do not substitute for official certification preparation. Consult your Workday partner or employer for accredited training paths.

Practice exams

Note: Workday does not publish third-party practice exams for this credential. Official practice is embedded in the certification course and accessed through Workday's Learning Management System (LMS).

Books

Book rule: Workday has not released an official exam-focused study guide. Most reference material is vendor documentation, community blogs, and internal Workday training materials. The Workday Community (forums + published guides) is the primary reference source. Dedicated textbooks are sparse; technical depth comes from hands-on experience in Workday Studio.
