I have the full SharePoint URL for a file, like: https://my-sharepoint-host.net/subsite/library/LOOONG folder name that exceeds the configured maxUrlLength value/fileName.txt

I need to obtain some details about that file: the listId and the fileID, so that I can then reach it with a link like https://my-sharepoint-host.net/_api/Web/Lists(guid'xxxxx-xx-xxxx')/Items(xx)/File .

But the original URL is too long, and I cannot used it in a /_api/web/GetFileByServerRelativeUrl(... HTTP Request.
If I try this, I get the message The length of the URL for this request exceeds the configured maxUrlLength value. from SharePoint.

What options do I have ?

What URL can I call to get those id field for the file ?

Thank you.

Have you tried reading the file from PowerShell? That should at least get you the GUID for the file:

Requires SharePoint PnP

$site_url = "https://my-sharepoint-host.net/subsite/library/"
Connect-PnPOnline  -Url $site_url -UseWebLogin
$Items = (Get-PnPListItem -List $list_name  -PageSize 2500).FieldValues    
foreach($Item in $Items)
  # echo out the file meta data, look for the document GUID
  • I don't have that option, I don't have access to powershell. I need to implement functionality for a tool which does HTTP requests...

  • There are third party tools that will do this. If you google "check for broken links in sharepoint libraries", you will find them. Apr 12, 2022 at 13:57
