The Unify API adheres to a "sparse" response pattern. In this pattern, if a property in the API response has an empty value, that property is omitted from the response. However, if the property has a non-empty value, it is included in the response.

Example Hubspot response: field hubspot_owner_id = null

This field is mapped to the Unify owner_id property.

Due to the “sparse” concept, it will not be included in the Unify response:

As soon as there is a value for the hubspot_owner_id, the Unify response will return the owner_id property with the value.
