Hello there @Logan ,
I use the viewer SDK and created an profile with free license key, then added it to WebViewer constructor but in my console it says
PDFJS.express: A valid license key is required to use the view only build of PDF.js Express.
and here is the WebViewer constructor
WebViewer({
licenseKey: 'added key here',
path: 'path/to/js/PDFJSExpress/lib', // path to the PDF.js Express'lib' folder on your server
initialDoc: 'some url here',
}, document.getElementById('viewer'))
and I followed the instructions in Manuall Integration.
thanks,
Kingie
