First Pass
Made API Destination its own step type:
- blue palette and a globe icon in radial menu
- editor:
- endpoint section with URL variable inputs
- full-screen payload editor modal: Expand button to enter it, Cancel/Confirm footer to leave it, with a white code block and a slate-100 gutter
- A Sample Event Data help modal so you can see exactly what shape the payload arrives in
- Edit / Add destination icon buttons
Architectural Pivot
After living with it, we moved API Destination from being its own step type into the Update action.
Polish
Closed it out with typography and spacing work — inline URL variable labels, tighter line-heights, shortened docs link copy, and moving the docs link down to the bottom where it belongs.
