/invite endpoint "notAllowed" but /createLink ok in Sharepoint via Graph API

Question

Hi,

I don't understand why I can create a sharing link via the POST /sites/{siteId}/drive/items/{itemId}/createLink endpoint but when I try to use the POST /sites/{siteId}/drive/items/{itemId}/invite endpoint I receive a 403 with this body:

{
  "error": {
    "code": "notAllowed",
    "message": "Operation not allowed"
  }
}

The api permissions needed to use one or another seems to be the same, so why I could be getting this error?

It also happens if I set the parameter "requireSignIn" to true and if I remove "sendInvitation" parameter.

There is something I can configure as admin in sharepoint or somewhere else to allow the /invite ?

Thanks

Hi @Lemo_admin

I tested the API locally and it worked fine for me. Also, when I call the endpoint using a GET request, it throws the same error as yours, so make sure you are using a POST request and not a GET request.

Hope this helps.

Hello @Lemo_admin ,

I am able to reproduce the issue from my end and noticed that request body is missed. Please refer below image where request body is empty.

Please refer to the documentation https://learn.microsoft.com/en-us/graph/api/driveitem-invite?view=graph-rest-1.0&tabs=http.

After providing a valid request body we are able to get 200 status code.

Hope this helps.
