# List departments

Retrieve a flat list of all departments within an organization.

Returns all departments belonging to the specified organization as a flat array. Each department includes its hierarchical metadata (`parent_id`, `path`, `depth`) so you can reconstruct the tree client-side if needed.

#### Path Parameters

**`organization_id`** string required

The unique identifier of the organization (format: `org_*`).

## Returns

An array of department objects.
