Using Fabric Restful API to Manage item permission

Hello jovialttu19 

Microsoft Fabric’s REST API currently has limited official support for managing granular item-level permissions like adding users to Lakehouses or GraphQL APIs.

Try these endpoints, I haven't tried these personally and these are not documented 

POST https://<region-redirect>.analysis.windows.net/metadata/access

GET https://<region-redirect>.analysis.windows.net/m/access/artifacts/<item-id>

The `POST /metadata/access` endpoint is used to grant permissions (e.g., ReadAll for Lakehouses).
• The `GET /m/access/artifacts/{item-id}` endpoint retrieves existing permissions for an item

To use these endpoints, your Entra ID app must have:
• Delegated permissions: `Item.ReadWrite.All`
• Workspace access: The service principal needs at least `Contributor` role in the target workspace

Let me know if this works 

Thankyou nilendraFabric for your response.

Hi jovialttu19,

Thank you for reaching out to the Microsoft Fabric Community Forum.

Based on my research, the Microsoft Fabric REST API offers limited official support for managing granular item-level permissions. The available official endpoint, Resolve Item Permissions, allows retrieval of permissions for the authenticated principal but does not support assigning permissions.

For permission management, it is advisable to use the Microsoft Fabric portal, which provides a user-friendly interface for assigning roles and permissions to users. You may refer to the following link for detailed guidance on the permission model and management:

We recommend staying updated on API developments by regularly checking the Microsoft Fabric REST API documentation for any official updates regarding permission management.
