It accepts an array of IDs so you can batch the request into a single call, which is significantly faster. ## OpenAPI ````yaml GET /quickbooks-desktop/unit-of-measure-sets/{id} openapi: 3.1.0 info: title: Conductor API version: 0.0.1 servers: - url: https://api.conductor.is/v1 security: - BearerAuth: [] paths: /quickbooks-desktop/unit-of-measure-sets/{id}: get: summary: Retrieve an unit-of-measure set description: >- Retrieves an unit-of-measure set by ID. **IMPORTANT:** If you need to fetch multiple specific unit-of-measure sets by ID, use the list endpoint instead with the `ids` parameter.

To ensure this set appears in the QuickBooks UI for companies configured with a single unit per item, prefix the name with "By the" (e.g., "By the Barrel"). **NOTE**: Unit-of-measure sets do not have a `fullName` field because they are not hierarchical objects, which is why `name` is unique for them but not for objects that have parents. example: Weight Units isActive: type: boolean description: >- Indicates whether this unit-of-measure set is active. Inactive objects are typically hidden from views and reports in QuickBooks.
