Body (from Message Center)

We are announcing the ability to debug flows using variable default values in Power Automate. This feature will reach general availability on June 15, 2026.

How does this affect me?
This feature allows makers to test and troubleshoot flows faster by setting variable default values directly in the designer, instead of restarting runs or manually preparing inputs each time. These default values are applied only during debug runs and do not affect production executions.

During debugging sessions, the default values are automatically applied when you start the execution from a specific step of the automation, enabling you to test specific scenarios without modifying actions or rerunning the flow from the beginning.

What action do I need to take?
This message is for awareness, and no action is required.
