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/build-assemblies/{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/build-assemblies/{id}: get: summary: Retrieve a build assembly description: >- Retrieves a build assembly by ID. **IMPORTANT:** If you need to fetch multiple specific build assemblies by ID, use the list endpoint instead with the `ids` parameter.
