Is there a property that indicates a ListItem has been shared?

Question

I need to extract sharing information for list items, I'm currently doing this with ObjectSharingInformation.GetObjectSharingInformation using the securableObject overload and passing the list item.

This works and I'm able to extract the info I need. However, I have to call this for every list item even though I know there are very few list items that have actually been shared. This results in many unnecessary requests and 429 Too many requests responses. I'm handling these with incremental retries but would like to avoid them altogether.

So, is there a property or field value I can check on the list item I already have that would indicate that the item has been shared? I'd like to limit my calls to GetObjectSharingInformation to only those items I know have actually been shared.

Answer 1

There is no specific property for if an item “have actually been shared”.

Consider using ObjectSharingInformation.SharingLinks to retrieve only items with Sharing Links generated.
