I am using microsoft teams api to fetch public channel message. With messages I also get attachments with a sharepoint URL as content URL. Now i want to download that file but it fails to download it. If i directly copy paste contentURL on browser, it downloads the file but if i do an http call, it fails. I cannot use sharepoint graph api(download by item ID) as i don't get itemID here. Is there any way to download those file? Any permission needed or any mistake i am doing on HTTP call?
