Beta — subject to change. This endpoint is publicly available, but its request/response shape may evolve before General Availability as we incorporate early feedback.

Searches sales orders using a structured filter body with nested logical operators (and, or) and per-field comparators. Use this when the flat query parameters on GET /sales_orders aren’t expressive enough. The response payload matches GET /sales_orders.

Only the fields listed in the request schema may appear in where and order; unknown fields return 422. Custom field values are addressable via custom_fields.<uuid> nested paths.
