Shopify Automation: Flow, Functions, and APIs

Most store work is a rule executed by hand: tag this order, discount that cart, sync the warehouse. Shopify gives you three layered ways to automate it, and the real skill is picking the shallowest one that works. This cursus covers Flow, the no-code trigger-condition-action builder that handles most of it; Functions, WebAssembly running inside checkout to change discounts, shipping, and validation as they happen; and the Admin GraphQL API with webhooks and bulk operations, where you gain full power and inherit software you own forever.
