# Business identifier

`GET /v2/book/{book_uuid}/business`

This API retrieves the business associated with a given `book_uuid`. It returns the business ID and display name, which can be used with business-level endpoints to access aggregated data across multiple <<glossary:Book>>s. 
A single business can have multiple Books. All books associated with the same business within your organization return the same business ID.

## Path parameters

- `book_uuid` string, uuid, required

## Response `200`

Success

- object
  - `id` string — Universally Unique Identifier (UUID) of the business entity. This is a stable identifier that is used with all business endpoints.
  - `name` string — Display name of the business. The name is determined in the following order: user-defined display name, org-specific name, then global entity name.

## Other responses

- `400` — Invalid Auth/Book UUID format
- `403` — Book not associated with requesting organization
- `404` — Business Identity Not Associated With Book
- `500` — Internal server error
