Posted on by Community Power Pla... Microsoft Employee

Hi Everyone,

Can any one please provide steps to add PDF viewer in app created.

I have my one drive for business with one PDF file.

When I attempt to view the PDF from the App getting an error with "Couldn't open PDF file". This link should let anyone view the PDF, so why is my PowerApp not able to view this?

Since OneDrive requires authentication, even for an anonymous link, I don't think a sharing link will work based on the limitations specified in the documentation since a sharing link still does authentication. See #3 from the list of limitations below.

Limitations

The security architecture of PowerApps requires the PDF Viewer to support only HTTPS links, not HTTP.

The Document property must link directly to the PDF file. Server redirects or HTML views of the document aren't supported.

The server that hosts the document must not require authentication.

You may not be able to view a PDF document in your app if the document resides on a server that has restrictive cross-origin resource sharing (CORS) settings. To resolve this issue, the server that hosts PDF documents must permit cross-origin requests from powerapps.com.

Thank You for your clarification,
Can it be possible to show a PDF document if it resides in SharePoint?

There are ways to do it, but it requires the use of Flow and and HTTP request. Here's a video that has a walkthrough.

There is actually a very easy to use workaround 🤗.

Assuming you have a Gallery control with the Items property set to a SharePoint or OneDrive Data Source for any given Document Library, all you need to do is set the Document property on the PDF Viewer control to:
Substitute (Gallery1.Selected.'{Thumbnail}'.Small, "transform/thumbnail", "transform/pdf" )

It doesn't really get any easy then that!
Try it and reply back on this thread if it works for you so other people also know...

@MasterOffice365
How does this even work? Using One Drive only offers Excel file connection. How would you connect it to anything except Excel?
