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

When updating this object, you must provide the most recent `revisionNumber` to ensure you're working with the latest data; otherwise, the update will return an error. example: '1721172183' name: type: string description: >- The case-insensitive name of this class. Not guaranteed to be unique because it does not include the names of its hierarchical parent objects like `fullName` does. For example, two classes could both have the `name` "Marketing", but they could have unique `fullName` values, such as "Department:Marketing" and "Internal:Marketing". example: Marketing fullName: type: string description: >- The case-insensitive fully-qualified unique name of this class, formed by combining the names of its hierarchical parent objects with its own `name`, separated by colons. For example, if a class is under "Department" and has the `name` "Marketing", its `fullName` would be "Department:Marketing". **NOTE**: Unlike `name`, `fullName` is guaranteed to be unique across all class objects. However, `fullName` can still be arbitrarily changed by the QuickBooks user when they modify the underlying `name` field. example: Department:Marketing isActive: type: boolean description: >- Indicates whether this class is active. Inactive objects are typically hidden from views and reports in QuickBooks. Defaults to `true`. example: true parent: anyOf: - type: object properties: id: anyOf: - type: string - type: 'null' description: >- The unique identifier assigned by QuickBooks to this object. This ID is unique across all objects of the same type, but not across different QuickBooks object types. example: 80000001-1234567890 fullName: anyOf: - type: string - type: 'null' description: >- The fully-qualified unique name for this object, formed by combining the names of its parent objects with its own `name`, separated by colons. Not case-sensitive. example: Parent:Child:Grandchild required: - id - fullName additionalProperties: false - type: 'null' description: >- The parent class one level above this one in the hierarchy. For example, if this class has a `fullName` of "Department:Marketing", its parent has a `fullName` of "Department". If this class is at the top level, this field will be `null`. example: id: 80000001-1234567890 fullName: Department sublevel: type: number description: >- The depth level of this class in the hierarchy. A top-level class has a `sublevel` of 0; each subsequent sublevel increases this number by 1. For example, a class with a `fullName` of "Department:Marketing" would have a `sublevel` of 1. example: 1 required: - id - objectType - createdAt - updatedAt - revisionNumber - name - fullName - isActive - parent - sublevel additionalProperties: false title: The Class object x-conductor-object-type: other summary: >- A class is a category used to group QuickBooks objects into meaningful categories. For example, classes can be used to classify transactions by department, location, or type of work. securitySchemes: BearerAuth: type: http scheme: bearer description: >- Your Conductor secret key using Bearer auth (e.g., `"Authorization: Bearer {{YOUR_SECRET_KEY}}"`). ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
