Is it possible to upload/publish an unlisted extension via the chrome webstore api?

Question

We are hoping to upload a chrome extension and publish it as unlisted (as the visibility option) via the Chrome Webstore Api.

So far we have been able to upload but not publish using this documentation -- we can't publish because extensions have a whole bunch of required parameters (like a screenshot or small-tile image) which we can't figure out how to attach. We are really hoping that one of these parameters will be visibility, and we can set it to "unlisted".

If any kind soul has any knowledge of the Chrome Webstore API, or how to set these parameters, our whole development team would be very appreciative.

The documentation on this is very sparse: https://developer.chrome.com/webstore/webstore_api/items/update

Quoting Using the Chrome Web Store Publish API:

Note: Currently, there is no API for setting an item’s metadata, such as description. This has to be done manually in the Chrome Web Store Developer Dashboard. More detail about the Web Store API can be found here.

So, to the question whether you can supply all the metadata programmatically - the answer is "no". And the Publish method does not seem to support "unlisted".
