## Responses

### 200

Depending on the type of event, the `initiator_id` parameter can be placed differently in response body (into the `request_content` object):
* only in the `meta` object if `event_name` is:
  * `document.update`
  * `document.complete`
  * `document.open`
  * `template.copy`
  * `document.fieldinvite.create` etc.
  * `document_group.update`
  * `document_group.invite.create` etc.;
   
* in the `meta` and in the `content` objects if `event_name` is:
  * `document.delete`
  * `document_group.delete`
  * `document_group.open`
  * `user.document_group.open`
  * `document_group.invite.declined`
  * `user.document_group.invite.declined`
  
The type of event also affects the composition of the parameters of the `request_content` object.
