QuickBooks Class API is one of 82 APIs that [QuickBooks](https://apis.io/providers/quickbooks/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification and an AsyncAPI event-driven specification. This API exposes 12 JSON Schema definitions. Tagged areas include Class. The published artifact set on APIs.io includes an OpenAPI specification, API documentation, an API reference, a getting-started guide, authentication docs, an AsyncAPI specification, and 12 JSON Schemas.

Class objects provide a way to track different segments of the business so they're not tied to a particular client or project. For example, you can define classes to break down the income and expenses for each business segment. Classes are available to the entire transaction or to individual detail lines of a transaction.
