Sharepoint + Graph API: Create Share Link doesn't work

Question

I try to create a share link of a directory on sharepoint via the Graph API, but I always get an "The operation failed because the object does not support sharing." error.

What I did

• Registered an app, according to the docs.
• Get a token without a user involved.
• Granted the app Files.ReadWrite.All, Sites.ReadWrite.All , Directory.ReadWriteAll permissions.
• Ran the following cURL

curl \
--request POST 'https://graph.microsoft.com/v1.0/sites/{site-id}/drive/items/{item-id}/createLink' \
--header "Authorization: Bearer ${TOKEN}" \
--header "Content-Type: application/json" \
--data '{"type": "edit", "recipients": [{"email": "******@gmail.com"}], "sendNotification": true}'

but I receive the following error

{"error":{"code":"notSupported","message":"The operation failed because the object does not support sharing.","innerError":{"code":"objectNotSupported","date":"2024-01-09T21:57:21","request-id":"xxxx-xxxx-xxxx","client-request-id":"xxxxx-xxx-xxxx-xxx"}}}

Via the UI creating share links work nicely without any problems, this is what puzzles me.

Hi Jurgen,

Maybe you can follow below steps to simulate creating the share link

Steps:
1. Get the drive Id
Use this endpoint https://graph.microsoft.com/v1.0/sites/1cpzfr.sharepoint.com,f0f575b8-513a-4d29-aced-944665acb461,60b419f0-5b77-4e7e-bb8b-d0c29288316b/drives

2. Copy the the drive id (for e.g id : b!uHX18DpRKU2s7ZRGZay0YfAZtGB3W35Ou4vQwpKIMWs3eEZky_dsSKJQhHoBQ80i) from the response object
Then request another call from this endpoint https://graph.microsoft.com/v1.0/sites/1cpzfr.sharepoint.com,f0f575b8-513a-4d29-aced-944665acb461,60b419f0-5b77-4e7e-bb8b-d0c29288316b/drives/b!uHX18DpRKU2s7ZRGZay0YfAZtGB3W35Ou4vQwpKIMWs3eEZky_dsSKJQhHoBQ80i/items?$filter=id ne ' ' 
This to get either folder id or files id, you can see it from response object

3. Copy the id (for my case i'm copying folder id : 01GJ2FQ63XXLW55ZYBN5BLL2VMNIEA5UWM)

4. Now request a create link endpoint 
https://graph.microsoft.com/v1.0/sites/1cpzfr.sharepoint.com,f0f575b8-513a-4d29-aced-944665acb461,60b419f0-5b77-4e7e-bb8b-d0c29288316b/drives/b!uHX18DpRKU2s7ZRGZay0YfAZtGB3W35Ou4vQwpKIMWs3eEZky_dsSKJQhHoBQ80i/items/01GJ2FQ63XXLW55ZYBN5BLL2VMNIEA5UWM/createLink
with Http Method POST and below payload or request body. Btw u can remove the password attribute to open share without entering password
{
  "type": "view",
  "scope": "anonymous",
  "retainInheritedPermissions": false
}

Here is the expected response. The webUrl is the shared link

Hope this helps.

Hi @Jürgen Drachta，

As the message said, the object does not support sharing. Currently the graph api only support us create sharelink for items. I feel regretful to inform you that it turns out to be a by-design one. You could refer to the following document

https://learn.microsoft.com/en-us/graph/api/driveitem-createlink?view=graph-rest-1.0&tabs=http#http-request

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.

Answer 3

Thanks for your answers!

WIth help of your answers, I could solve my problem!

The key was the following:

• I needed to use the following request `https://graph.microsoft.com/beta/sites/<site-id>/drives/<drive-id>/items/<item-id>/createLink, where
• <item-id> is found out via https://graph.microsoft.com/v1.0/sites/<site-id>/drives/<drive-id>/root /children and not via https://graph.microsoft.com/v1.0/sites/<site-d>/lists/<list-id>/items/.

Then everything works as expected, eventhough sendNotification=true seems to be a bit buggy, as it doesn't send out mails. But this is something I can live with ;-)
