# Fabric REST API patterns Base URL: `https://api.fabric.microsoft.com/v1` ## Finding Workspaces and Items 1. List workspaces: `GET /v1/workspaces` → paginate with `continuationToken` 2. Find by name: iterate results until `displayName` matches 3. List items in workspace: `GET /v1/workspaces/{wsId}/items?type={ItemType}` 4. Type-specific endpoints return extra `properties` (connection strings, etc.): `GET /v1/workspaces/{wsId}/{lakehouses|warehouses|notebooks|semanticModels|...}` 5. Cross-workspace discovery (no `wsId` in path): `POST /v1/catalog/search` with `{ "search": "Sales Revenue", "pageSize": 50, "filter": "Type eq 'Lakehouse'" }` → permission-trimmed items (each with `id` GUID + `workspaceId`) across your whole accessible estate, by catalog metadata (name/description/workspace name). OneLake Catalog Search API (Preview, March 2026); same capability as the `fab find` CLI verb (fabric-cli skill) and the Fabric Core MCP server's `search_catalog` tool. ## Sensitivity Labels on Item Responses As of March 2026 GA, `List Items` / `Get Item` / `Update Item` responses include a `sensitivityLabel` property on the `Item` object when the item has a Purview information-protection label applied: ```json { "id": "34fa05fc-e7ba-435a-b1ab-63534b6aa4f9", "displayName": "PDF_Env", "type": "Environment", "workspaceId": "2ae4b0b9-895b-4676-bfcd-125b1f20e34d", "sensitivityLabel": { "sensitivityLabelId": "4922deb9-fe99-4f4f-971c-9bdf556ec6a9" } } ``` **Field name gotcha
