ScopeId value for the sharepoint site, web and list/docLib.

Question

Recently, I came across a GUID property in SharePoint called ScopeId, which represents the permission inheritance status. However, I’m not sure how to retrieve its value at the site/web and list levels using CSOM or the REST API.

I am able to see the ScopeId value at the list item level. Currently, I can also retrieve the values for the web and list levels using the AsyncReadJob API.

This is the property I am referring to, which I obtained using AMR (AsyncReadJob API). Does anyone know how to retrieve the ScopeId value at the site/web and list levels?

Hi @Tony

First, I’d like to clarify that this is a user‑to‑user support forum. Moderators participating here do not have access to backend systems, nor can we directly intervene in Microsoft product functionality. Our role is limited to providing technical guidance and sharing best‑practice recommendations based on reported issues, requests, and scenarios.     

Currently, I have not found any native approach to retrieve the actual permission ScopeId GUID for a SharePoint Site (SP.Web) or List (SP.List) using either standard CSOM or the public SharePoint REST API. 

Based on my research, although the ScopeId property can be queried on ListItem objects, Microsoft treats ScopeId as an internal system identifier at the Web and List architectural levels. As a result, it might not exposed as part of the public API contract for endpoints such as /_api/web or /_api/web/lists. 

Even though CSOM assemblies expose constants like ClientConstants.ScopeId, these constants are reserved for internal client payload mapping (primarily for list items) and do not represent a loadable property on SP.Web or SP.List objects. Some internal services (for example AsyncReadJob–based pipelines) may surface a ScopeId value, but these APIs are not documented or supported for custom solutions and should not be relied upon in production implementations.

To help you reach your goal more effectively, I recommend engaging with  [GitHub Community Forum] for a deeper technical dive or to connect with individuals who have relevant experience and expertise. Some approaches may behave differently or be restricted depending on your specific environment and configuration.

Apologies for redirecting you to the related development team support. As moderators in this community, we do not have access to your specific tenant configuration, and my testing environment is limited. Therefore, my guidance is based on available Microsoft documentation and resources. That said, I’ll do my best to provide additional insight where possible.  

I hope this helps.

ScopeId is exposed in CSOM and REST only as a string property name/constant; there is no documented CSOM or REST property that returns the permission scope GUID for site, web, or list objects directly.

In CSOM, the related members are:

• ClientConstants.ScopeId – a constant string field.
• FieldPropertyNames.Scope, ViewPropertyNames.Scope, UserCustomActionPropertyNames.Scope, and ContentTypePropertyNames.Scope – constant string field names.
• View.Scope – exposes a ViewScope enum, not the permission scope GUID.

These APIs provide names and view scope information, not the underlying permission inheritance ScopeId value that AsyncReadJob returns. The context does not document any supported way to read the same ScopeId GUID for site/web/list via CSOM or REST.
