Hi @Ankit, it is not possible to update contacts by their label. You must use the internal value with every HubSpot endpoint. You can find the internal values by going to the properties page (https://app.hubspot.com/property-settings/HUBID/) and clicking into a specific property. Or you can pull the internal values using this endpoint: https://developers.hubspot.com/docs/methods/contacts/v2/get_contacts_properties
