Update existing post with Craigslist API

Question

I need to automate adding images to some existing posts via Craigslist API.
The documentation at http://www.craigslist.org/about/bulk_posting_interface states:
Note: If you submit a posting item with the same rdf:about as an existing posting item, the existing posting item will not be updated. Presently the only way to alter the content of a posting is via URL specificed in the cl:postingManageURL element.
This is pretty vague. The way I understand this is, you first have to attempt a post, get a URL back and then it's unclear what to do next.
Has anyone tried this? Ideas?
Thanks, Andy

Answer 1

I haven't played with this API, but when I see this:

<cl:postingManageURL> - In post mode, this element will contain a URL that can be used to edit or delete the new posting.

That leads me to believe that all you need to do is make sure your request is an HTTP POST with the same postingManageURL as the post you want to edit. Then provide the previewHTML you want to update the post with.

As of now, CL does not provide an API to update ads using the bulk posting API. I have tested all kind of things by including the manage url, including the live ad url etc. Nothing seems to work.
