External preview extension
OpenKM 7.1 comes with two user interfaces, called "classic" and "kcenter". Although both functionally are very similar, the layout and the way they are used may have significant differences. This page is based in the "classic" user interface. If you are using the "kcenter" user interface and have any doubts to access any of these features, please create a ticket in the support website.
The External Preview feature helps you to preview documents based on external URL request.
This option is only available if you have enabled the External preview feature.
There are two parameters passed as request parameter in URL request:
- The document uuid.
- The downloadUrl.
