  title: Shopify Find Collection and List Its Products
  summary: Find a custom collection by title, then list the products it contains.
  description: >-
    A storefront merchandising read flow. The workflow searches custom
    collections by title and branches: when a collection matches it lists the
    products that belong to that collection, and when none matches it ends
    cleanly. This lets a caller resolve a human-friendly collection name into
    the products that should be displayed for it. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
