I'm looking at getting a thumbnail image of documents when uploaded into a document library. I can see the thumbnail preview when I click on ellipses (...) context menu of the document. Is there a way to somehow get this document using Rest API?
I did try the below for a .png file.
https://tenant.sharepoint.com/sites/test_layouts/15/getpreview.ashx?path=https%3A%2F%2Ftenant.sharepoint.com%2Fsites%2Ftest%2FTestWork.png
It worked for .png file but not for word, excel or PDF documents.
Thanks in advance
