post https://api.whippy.co/v1/custom_objects//records
Creates a new custom object record.
The custom object with its custom properties must be created before creating a custom object record.
The associated_resource_id field is used to associate the custom object record with a Whippy resource.
The associated_resource_type field is used to specify the type of the Whippy resource e.g. contact, conversation, message, tag.
The properties field is used to specify what custom properties should be set for the custom object record and their values.
If the custom object has a required custom property, and its key is not present in the properties field,
then the default value of the custom property will be used.
