  title: Salla Upsert Product by SKU
  summary: Find a product by keyword and update it if it exists, otherwise create it.
  description: >-
    A common catalog synchronization pattern. The workflow searches the
    product catalog for an existing product matching a SKU or name keyword and
    then branches: when a match is found it updates that product in place, and
    when no match is found it creates a new product. Each step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
