從第一封測試信，到正式上線，每一步都說人話。

const response = await fetch(
  `${process.env.FORWARD_BASE_URL}/api/v1/emails`,
  {
    method: "POST",
    headers: {
      Authorization: `Bearer ${process.env.FORWARD_API_KEY}`,
      "Content-Type": "application/json",
      "Idempotency-Key": "first-test-v1"
    },
    body: JSON.stringify({
      from: "Forward <sandbox@forward.test>",
      to: "delivered@forward.test",
      subject: "我的第一封 Forward 測試信 ✨",
      text: "這封信不會離開 Forward。"
    })
  }
);

const email = await response.json();
console.log(email.id, email.status, email.test_mode);
