  title: WooCommerce Upsert Product Category
  summary: Find a product category by slug and create it only if it does not already exist.
  description: >-
    A common catalog maintenance pattern. The workflow searches existing product
    categories for one whose name matches the supplied value, then branches:
    when a match is found it reads the existing category, and when no match is
    found it creates a new category. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
