  title: WooCommerce Upsert Customer by Email
  summary: Find a customer by email and create the account only if it does not already exist.
  description: >-
    Avoids duplicate customer accounts when importing buyers. The workflow
    searches existing customers by email, then branches: when a match is found
    it reads the existing customer, and when no match is found it creates a new
    customer account. Every step spells out its request inline so the flow can
    be read and executed without opening the underlying OpenAPI description.
