Null values

JSON messages with null values are supported by web service calls and Blueriq as a Service.

Incoming JSON messages containing properties with null values are allowed for non-required properties. When a property is specified as non-required 

When a response to a REST JSON web service call contains properties with null values these properties will be handled as non-existent properties. This means that null values are only accepted for properties that are specified as non-required in the response domain schema. Non-required properties on request domain schemas are not present in the actual request that the web service call creates, so there won't be any null values in web service call requests.

HTTP status codes
