Shopify has increased the active functions limit from 5 to 25 per Function API, giving developers significantly more flexibility in their custom commerce logic. This expansion applies to payment customizations, delivery customizations, cart and checkout validations, and fulfillment constraints. Developers can now split complex workflows into smaller, more manageable dedicated functions rather than bundling everything into monolithic implementations.
This change fundamentally improves code organization and maintainability for Shopify developers. With 5x the function capacity, developers can now modularize their logic, making it easier to test, debug, and update individual functions without affecting others. This is particularly valuable for larger stores with complex business rules around payments, shipping, and checkout flows—teams can now assign different functions to specific concerns rather than creating complicated nested logic in a single function.
If you're building Shopify apps that manage custom functions across multiple stores, GetShopifyToken provides secure, reliable OAuth token management to authenticate your function deployments at scale.
