Workflow Functions

Run your own JavaScript or TypeScript directly inside Shopify Flow - no servers to host. Transform data, calculate values, format text, evaluate conditions, call external APIs, and read or write store data, then pass custom outputs to the next Flow step. Generate functions with AI (Claude or OpenAI), start from verified templates, sync to GitHub with full version history, run on a schedule, and manage it all over a REST API and MCP. Build advanced automations - no external service required.
