  title: Intuit Find or Create Customer
  summary: Look up a customer by display name and create it only if missing.
  description: >-
    An idempotent customer upsert for QuickBooks Online. The workflow runs a
    SQL-like query against the Customer entity filtering on DisplayName, then
    branches: when the QueryResponse already contains a matching Customer it
    reads that customer back, and when no match is found it creates a new
    Customer. This avoids duplicate customers, which QuickBooks rejects because
    DisplayName must be unique. Every step spells out its request inline so the
    flow can be read and executed without opening the underlying OpenAPI
    description.
