I try to relabel Organization as "Entity":
$result = civicrm_api3('ContactType', 'create', array( 'label' => "Entity", 'api.ContactType.get' => array('name' => "Organization"), ));
This errors out with
Mandatory key(s) missing from params array: name, parent_id
Apparently I don't understand chaining and the required 'id' for updating is not returned. What is wrong in my reasoning?
