Metafield triggers and additional topics are now available for Events
Shopify developer change
MerchantDiff detected this entry in Shopify's official developer changelog on July 21, 2026.
This Shopify update is categorized as API, Update, Events & webhooks.
What changed
Apps can now subscribe to events for Order, Collection, InventoryItem, InventoryShipment, Location, and can subscribe to metafield changes on Product, Order, Customer, Collection and Location. ProductVariant metafields are supported through the Product topic. This gives apps a precise way to react to more objects and custom data changes. Apps can target the fields that matter in triggers, query the resource that changed, and avoid subscribing to every resource update just to diff payloads in their event handler. Both $app metafields and regular metafields are supported.
Who is affected
Apps that subscribe to or process Shopify webhooks or event payloads should review this change.
What action may be needed
Review whether the new capability is relevant to your app. If you plan to use it, test the affected API or workflow before adopting it in production.
