To update the existing record you should know the record ID and use a PUT request with application/json or application/x-www-form-urlencoded content type of PUT/POST body. Received values will be casted according to the class defined in QuickBlox Dashboard.
A field that is present in class but not specified in the PUT request has a null value. To nullify the existing value you should specify null for application/x-www-/form-urlencoded, and null for application/json content type.
An update request updates specified fields only (i.e. other fields will be left untouched). For numeric fields Integer and Float, there is a special increment operator inc that increments or decrements the numeric field.
