removeProperty — Power Automate (WDL) function reference

Drop a field.

Syntax

wdl

removeProperty(object, property)

wdl

removeProperty(item(), 'Temp')

→ New object

Useful before forwarding a payload to an external system.

wdl

removeProperty(triggerBody(), 'InternalNotes')

→ The trigger body without the InternalNotes field

wdl

removeProperty(setProperty(item(), 'Status', 'Archived'), 'TempFlag')

→ The item updated and cleaned up in one expression

Removing a property that doesn't exist does not throw — it silently returns the object unchanged, the opposite of addProperty()'s duplicate-key error.
Only removes a top-level property named exactly as given — to strip a nested field you must drill in and reconstruct the parent object.
