Hi @Peter Xiang 

The 401 Unauthorized happens because your specific resource path (with PATCH) is not matching exactly with what ServiceNow expects. When you enable Apply to all resources, it bypasses that strict match and applies globally.

When you check Apply to all resources, the policy applies to every resource under that REST API regardless of the specific resource path → so authentication works fine → you get 200 OK.

Please mark this Helpful and Accepted Solution if this helps you. Your action will help me and the community in understanding same requirements.

Thanks & Regards
