About the "In Stock" Metafield Source

When a warehouse is marked as the "In Stock" Source, Cydekick writes a custom.in_stock boolean metafield to each Shopify product whenever inventory is synced. The product is marked true when that warehouse has stock > 0, and false when empty.

The metafield is visible under Unstructured product metafields in the Shopify product page. To make it appear on the product edit page as a standard field, create a definition in Shopify → Settings → Custom data → Products with namespace custom, key in_stock, type Boolean.

Only one warehouse per channel can be the "In Stock" Source — enabling it on one will automatically disable it on any other.
