I am able to set Klaviyo and custom properties with API calls but cannot clear/blank out the property value. I can not do it through the interface or with the API. For example if I set Location to “NY” and want to then set it to blank, neither the interface or API will allow it. Through the interface I can remove the property. I would prefer blanking it out but if that is not possible is there a way to remove the property through the API?
