About Zapier Functions
Zapier Functions lets you write and run TypeScript or JavaScript without managing servers, then wire that logic into Zaps, Interfaces, and 8,000+ app integrations. Author code in a built-in editor with instant deploys and versioned edits, call external APIs, enrich data, and return structured outputs for the next Zap step. Use Functions to blend low-code and code: keep Zaps readable while handling tricky transformations, validations, and business rules in TS/JS.
