Workday offers a Workday Studio application (called "Eclipse") that allows you to test integrations using Workday's very own integration infrastructure. It has been designed for developers.
Here I document my steps in installing Workday Studio on my Mac OS.
Workday describes it as being:
- Run your Workday Studio integrations like any other Workday integration - configure, launch, schedule, monitor, and even audit your integrations.
- Use powerful and productive development tools optimized for interacting with your Workday tenant.
- Build sophisticated and highly customizable integrations without the need to own or manage any on-premise integration middleware or servers.
