Building a workflow that connects to an external app has always involved a degree of guesswork. You configure the action, publish the workflow, and hope it runs the way you expected. ESC Hub has added a Test Action feature that removes that uncertainty.

What's changed

There is now a Test Action button on every external-app action step inside the Workflow Builder. Click it and the action runs as a real live call against the connected app - using the exact inputs you have configured, with workflow variables, custom values, and transformations applied exactly as they would be at runtime.

A Test Drawer slides in from the right showing two panes side by side. Data In shows the resolved inputs being sent to the provider after all variable interpolation. Data Out shows the raw response coming back. Key fields surface as chips and cards above the expandable JSON so you can see what matters without digging through the full payload.

The test uses the same Connected Account the action will use when the workflow runs for real, so what you see in the test is what will happen in production.

Why it matters

Catching a misconfigured integration action after a workflow has already run on real contacts is frustrating and sometimes hard to undo. Being able to validate the exact payload going out and the exact response coming back - before anything goes live - means you can build with confidence and fix issues at the right time.
