This Api works as un upsert. If the key_identifier's value used to search is not present, a creation will be made. Otherwise an update will be performed with the key requested. Please consider that the key already present in database can not be updated with this Api.
Attention: the uuid in this case will be autogenerated by BE.
Attention: If you use the sku as a key, uuid in the body will be ignored and will be preserved the uuid in the database.
