I would like to fetch more information for an embedded Issuu player via the Issuu API, but it seems that the new embeds dont carry the documentIds anymore, but a configId.
The API however only works with the documentId.
Example embed:
<div data-configid="0/919xxx" style="width: 525px; height: 356px;" class="issuuembed"></div><script type="text/javascript" src="//e.issuu.com/embed.js" async="true"></script>
or
<iframe width="525" height="356" src="//e.issuu.com/embed.html#0/91xxxx" frameborder="0" allowfullscreen></iframe>
So how can i get the documentId when i only have the configId?
