===Format rules===
==Dates==
All date and time values are displayed as integer numbers and represent the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT), like [[http://php.net/manual/en/function.time.php|PHP time()]] function. The date/time property type in the specification is specified as “Time”, the actual JSON type is “Number”.

  * **201** : the object has been created
  * **204** : the object has been destroyed
  * **400** : any kind of logical error (missing parameters, invalid operation, constraint violation etc.)
  * **403** : access is forbidden (authentication or authorization failure)
  * **404** : object not found
  * **405** : HTTP method not allowed (for example if you try to update a read-only object)
  * **411** : length Required (if the request body is empty for methods that require it)
  * **422** : unprocessable entity (missing parameters, invalid operation, constraint violation etc.)
