We have been using a custom web part for handling comments on SharePoint pages. For connecting the comments to the page we used Open Graph and the page object. We're now moving our news archive to a new site and for keeping the comments we would need to update the open_graph web_url.
However it doesn't exist any documentation on this in the Yammer developer site. I can only find a way to fetch the object using the REST API but no update method. Can someone provide information if this is possible at all?
