In this Workday Developer Program Deep Dive, DevRel Engineer Marek Wichtowski walks through Workday Orchestrate Copilot — from rapid prototyping with Business Process Templates to AI-assisted integration generation using specs, rules files, and custom skills. 🔧 WHAT YOU'LL LEARN ✅ Best Practice of the Month: Prototype First, Build Later Why you should prototype with the Workday Business Process Template instead of spending time planning How to iterate on orchestrations without saving or deploying — the built-in debugger lets you run logic instantly Using custom aggregations to build maps, lists, and structured JSON outputs inside a loop ✅ Something We Learned: Augmenting Copilot Behavior with Attachments How attaching a structured spec file (Markdown) produces dramatically better Copilot output than typing in chat Why including your SOAP XML request as an attachment prevents Copilot from hallucinating API calls How to prep a spec using external AI tools (like Gemini) and then clean it up for Copilot consumption ✅ Workday Orchestrate Copilot — Deep Dive Demo: Live walkthrough: generating a 9-step inbound integration from a Markdown spec in under 20 minutes Adding error handling via Copilot prompts vs. encoding it into reusable rules The difference between Rules files (orchestration-specific, reusable across sessions) and Skills (named, invocable patterns scoped to a thread) How to combine a skill and a rules file in a single Copilot session for layered generation quality Using the built-in Audit skill to validate your orchestration against your own rules and surface violations Accept vs. Decline in Copilot — why you should save checkpoints before iterating Why Copilot currently generates single orchestrations (not multi-orchestration flows) — and how to work around it Using WDCLI to download, version-control, and redeploy your Orchestrate apps locally 📌 CHAPTERS 0:00 Welcome & Forward-Looking Statement 0:34 Developer Program Update: DevCon Recordings & YouTube Playlist 2:00 Best Practice of the Month: Prototype Without Deploying 5:00 Live Demo: Custom Aggregations & Test Data Generation 11:30 Introducing Orchestrate Copilot: Overview of Edit Mode, Ask Mode & Threads 13:30 Demo: Generating an Integration from a Markdown Spec 17:00 Adding Error Handling via Copilot Prompt 20:30 Rules Files: Enforcing Patterns Across Orchestrations 24:30 Skills: Reusable, Named Patterns for Copilot Generation 28:00 Combining Skills + Rules for Compliance Auditing 31:00 Fixing Violations & Accepting Copilot Changes 33:00 Q&A: Local Folder Compatibility, Downloading Rules, Writing Skill Files 41:00 Q&A: WDCLI Basics, SKU Availability, Sub-Orchestrations, Third-Party Agents 👩‍💻 WHO THIS IS FOR Workday Developers building integrations and automations on the Workday platform using Workday Orchestrate, Orchestrate Copilot, WDCLI, SOAP APIs, and JSON-based inbound integrations. 🔗 RESOURCES 💻 Sample rules files, skill files, and spec: https://forum.developer.workday.com/t/developer-program-deep-dive-june-2026-orchestrate-copilot/42936 📺 Subscribe to the Workday Developer playlist for new content every week: https://www.youtube.com/playlist?list=PLH6Be9QWl1EzkL3NFBlXMPM7JUl2qYz_u 🛒 Get your Workday Developer swag: https://workdaystore.com/WD29/Workday/Developer/ 📝 Submit a pitch for the Workday Developer Blog: https://forms.gle/RtfjUBB2df8eLAED8 📍 Find a developer meetup near you or sign up to host: https://luma.com/workdaydevelopermeetups 📅 This is a monthly series — future Deep Dives will cover advanced Orchestrate patterns, Extend optimization, and API consumption analytics. #WorkdayDeveloper #WorkdayOrchestrate #OrchestateCopilot #WorkdayIntegration #WorkdayBuild #AIAssistedDevelopment #WorkdayExtend #WDCLI #EnterpriseIntegration #LowCode #WorkdayDeveloper #WorkdayOrchestrate #WorkdayExtend #APIOptimization #WorkdayIntegration #WQL #WorkdayDevelopment #LowCode #EnterpriseIntegration
