Downloading an image contained in a SharePoint List with MSGraph

TourmenteT 30

Hi, I would like to download an image contained in a SharePoint list (SiteAssets library) using Microsoft Graph API. The issue is that I can't find the ItemID needed to download the file using this documentation. How can I access the content of SiteAssets using MSGraph ? I've read on another post that this is not possible but it goes back one year ago and the Feedback page mentionned is down. Thanks for your help.

Hi @TourmenteT, Per my research, there is no update about download file from SiteAssets library by graph. Currently we are still unable to access the files in SiteAssets library using graph. It is highly recommended that you can vote this ticket. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future. Thanks for your understanding. Since the issue is a by-design one. As a workaround, I would recommend you to use rest api to access SiteAssets library. Please refer to following api

https://xxx.sharepoint.com/sites/xiexin/_api/Web/GetFileByServerRelativeUrl('/sites/xiexin/SiteAssets/test.jpg')/$value

Hi Thank you for your answer. I've created a feedback on the site you've given me. As for Rest-API, here is the issue I'm getting :

Error occured while trying to download SharePoint image: ('-2147024891, System.UnauthorizedAccessException', 'Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))', "403 Client Error: Forbidden for url: https://redacted.sharepoint.com/sites/MySite/_api/Web/getFileByServerRelativeUrl('%2Fsites%2FMySite%2FSiteAssets%2FLists%2F9ed58b89-84d8-4a38-a7fd-4b85a21ffda4%2FImage.png')?$select=ServerRelativePath,Id")

site_url = "https://redacted.sharepoint.com/sites/MySite/"
client_id = "redacted"
client_secret = "redacted"

context_auth = AuthenticationContext(site_url)
context_auth.acquire_token_for_app(client_id, client_secret)
ctx = ClientContext(site_url, context_auth)

try:
	file_object = io.BytesIO()
    file = ctx.web.get_file_by_server_relative_url(relative_url)
    file.download(file_object).execute_query()
    file_object.seek(0)

    with open(os.path.join(folder_path_images, file_name), "wb") as local_file:
        local_file.write(file_object.read())
except Exception as e:
    print(f"Error occured while trying to download SharePoint image: {e}")

Thank you
