From first file to live workflow.

Build your first action.

Start with one clear result, then connect it to your workflow.

exports.main = async (event) => {
  const email = String(event.inputs.email ?? "");

  return { text: email.trim().toLowerCase() };
};

Try the input { "email": " J.Chen@Example.com " }. The returned value is { "text": "j.chen@example.com" }. Follow the quickstart to test and publish it.
