Edit Value via Webhook

[FatLou]

I am trying to set a value to blank using a webhook. Basically if an option is deleted from Table A I want the value Group by in Table B to be set to empty. The webhook is filtering the data properly it just is not setting the value to empty (clearing the value).

{
“Action”: “Edit”,
“Properties”: {
“Locale”: “en-US”,
“Location”: “47.623098, -122.330184”,
“Timezone”: “Pacific Standard Time”,
},
“Rows”: [
<<Start: FILTER(“PropertyandTenantLeasingActivity”, AND(([Properties]=[_THISROW].[PropertyID]),[Group by]=[_THISROW].[Space or Category]))>>
{
“ID”: “<<[ID]>>”,
“Group by”:
},
<>
]
}
