Using PDF files from Google Drive/Dropbox or another domain!

This is a frequent question. It’s understandable when users want to save bandwidth/time and use files from third party domains or File sharing domains.

But this requires proper CORS access permission from that external domain.
One simply cannot use PDF files from another domain without proper CORS permission set.

Remember! The permission has to be set on that third party domain(which has the PDF file), not in your domain where the flipbook will be displayed.

How to set?

Or it can be available in your provider’s settings or control panels too!.

File sharing providers like Google Drive, Dropbox, One Drive are not known to provide any CORS access!
