I need to clear the “Work Email” fields to blank. When I try $$CLEAR$$, ___BLANK___, “ “, , “” etc.
I get an email validation error. I know it is possible to update via the API. If I am unable to use the clear field, might need to code the API to clear the field. Thank you.

I was able to add a step using the KNACK connector. In the connector there is an option for API Request Beta, I added this item.
URL =
https://api.knack.com/v1/objects/object_16/records/(KNACK USER ID FOUND FROM A FIND PREV Step)
The URL will update the Individual (object_16) for record, Knack Record ID.
NOTE: You will need to figure out the object for your instance, The easier way is look at the Knack plugin. So if you have a find Knack, in the criteria you will see Objects, when you click on that you will see the object numbers under the names, this is the object # you will need for the API URL
Method: Put
Additional Headers: Content-Type application/json
In the Body Field I added the following, knowing that the field # for work email is 109. You can get the field number when you go to knack and inspect the field you want, it will show you the field number.
{"field_109":null
"field_109_raw":null
}
TADA! This will clear the email field (which in our knack is Field 109) via the API. You do not have to worry about authenticating as this is handled from the Knack connector itself.
Hope that helps someone else.

Unless the field tooltip explicitly indicates how to clear a field value with another specific value, you’d likely have to use the the app API to clear a field value.
+5Hello
This is expected behavior.
If the field is validated as an email, Update actions usually won’t accept empty values like CLEARCLEARCLEAR or blank strings. Leaving the field unmapped just means “don’t update,” not “clear.”
A couple quick things to check:
If the app has an overwrite or replace existing value option, enable that.
Try Utilities by Zapier Line-itemizer Create with nothing mapped. Some apps treat that as a true empty value.
If that still fails, Webhooks by Zapier with a Custom Request is the reliable route. Calling the app’s API directly lets you set the field to null or empty and bypasses Zapier’s validation.

Thank you for your replies. I will go the API route. I just wanted to make sure there wasn’t some type of clearing variable, etc.
