Get sharing link using GET /shares/{shareIdOrEncodedSharingUrl} does not work across Tenants

Hi!
I need to just validate if a link is a legitimate sharing link.
To perform this, I just call the GET /shares/{shareIdOrEncodedSharingUrl} Graph endpoint.
In {shareIdOrEncodedSharingUrl} I encode the link I want to analyze to base64.
If that link belongs to the same tenant than the user doing the query, it works... but if the sharing link belongs to another tenant, it does not work (error 403).

I am using Graph Explorer and I tried specifying redeemSharingLink or redeemSharingLinkIfNecessary in the Prefer header but it's the same.

In the documentation it does not mention that the sharing link needs to belong to the same tenant.

Thanks

Hi @PabloGlomby-5415,

Per my test, I got the same result as yours on my end. Currently, the GET /shares/{shareIdOrEncodedSharingUrl} endpoint can only get shared DriveItems in the same tenant.

As a workaround, you could use https://graph.microsoft.com/v1.0/me/drive/sharedwithme?allowexternal=true to list the items shared with me, it would conatain external items.

Thanks but this is not what I am searching. I want to at least know if a given URL is a valid sharing link or not (even if I cannot get the file name).
If I get a URL belonging to AnyoneCanView, sharedwithme will not return it.

Thanks

If so, you have to in the same tenant. It cannot access shared items in other tenants
