# Updated Built for Shopify requirement for fulfillment services callback response rate

Built for Shopify requirements about [responding to callback requests](https://shopify.dev/docs/apps/launch/built-for-shopify/requirements#respond-to-callback-requests) for fulfillment services apps are changing. The threshold for responding to Shopify [callback requests](https://shopify.dev/docs/api/admin-graphql/latest/objects/FulfillmentService) in the previous 28-day window is changing from 99% to 100%. The updated requirement comes into effect in July 2025.
