Hi ​@FBreitenkamp ! 

Using "null" in a request will result in that value being removed, essentially. So for example, if someone put phone number: "null", it would result in nothing if there was already no phone number, and it would erase it if there was.

The "null" field is usually used with POST requests, and the Get Profiles is a GET request. So it is true that this isn’t possible with this specific endpoint. 

I hope this helps, and let me know if you have any follow up questions!
