Hi Antonio ,  

Thank you for contacting Syncfusion Support. 

We can load the PDF document as byteArray in the PDF Viewer from the server side using the Load() API in the WebAPI controller. Please find the code snippet from the below, 

Private viewerHelper As New PdfViewerHelper() 
Dim docBytes = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Data/PdfViewer/HTTP Succinctly.pdf")) 

We have created the sample for the same and shared in the following location, 

Please find the below KB link for reference, 

Please try this revert us with more details if you have any concerns on this.
