  title: Shopify Restock a Product Variant
  summary: Read a variant to find its inventory item, resolve a location, and set the available quantity.
  description: >-
    Restocks a specific product variant by quantity. The workflow lists the
    product's variants to resolve the variant's inventory item, lists locations
    to resolve the target location, and sets the available quantity for that
    inventory item at that location. This is the variant-centric entry point for
    keeping stock accurate. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
