Hi Chris,
The request has resurfaced to be able to clear Recipient/Occasion/Style and we are still unable to reset any of these fields. I must admit that re-testing this back when I received your response below escaped me.
If we pass a null with the field, the param gets ignored by the updateListing call. If we pass a style with a single blank space, it gets accepted as a valid style and returned as an empty element and not a null. if we pass any value other then the described enums for recipient or occasion fields, then we receive an error response.
If your testing is proving that you can clear these fields with the updateListing call, then please document so that we can see how you are doing it. If it is a bug then please advise when it will be resolved and documentation on how to correctly clear these fields.
Thanks,
G.
