I added the demo script below to my site with my client ID and it pulls in the pdf sample file as expected (URL in red). I then added my own pfd URL and it fails to work. I get a "File preview not available, please reload to try again" error. Here's the pdf I was trying to display: https://medpower.com/s/himycasstatesubmissionfilecreation.pdf
Do I have to save the source PDF files in a special way or on a special website before I can pull them in using the PDF Embed API? I don't understand why the demo URL works, but mine does not. Any help you can provide is greatly apprecaited!
FYI, here's the code I used that substitutes our pdf URL:
As I understand it, when you create credentials you have to fill in the exact domain name where your files will reside. And it must be exact. For example, mxdpower.com is not a substitute for www.mxdpower.com.
