How to get Document Thumbnail via Rest API (SharePoint online - classic experience) for excel, word and pdf files?
Frage
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
Lösung
Not sure if you know rest api but This should return the url of the thumbnail -->
/_api/web/lists/getbytitle('title')/items(itemid)?$select=EncodedAbsThumbnailUrl
