400 public key is required with restful api

[zhiwzhao]

my code as below, but still get error . why ? i make sure the public key is correct.

// ========== 配置信息 ==========
var USER_ID = "2Uia********1zC4";           
var SERVICE_ID = "service_xe5rgst";
var TEMPLATE_ID = "template_unlqucm";

// ========== 邮件参数 ==========
var templateParams = {
  to_name: "张三",
  to_email: "[email protected]",
  from_name: "开工大吉",
  subject: "开工大吉",
  message: "这是测试邮件，开工大吉"
};

// ========== 发送请求 ==========
var url = "https://api.emailjs.com/api/v1.0/email/send";

var headers = {
  "Content-Type": "application/json"
};

var data = {
  service_id: SERVICE_ID,
  template_id: TEMPLATE_ID,
  user_id: USER_ID,                    // ✅ 使用原始 Public Key（无 user_）
  template_params: templateParams
};

// 发起 POST 请求
console.log("请求数据:", JSON.stringify(data, null, 2));
var res = http.post(url, JSON.stringify(data), headers);
var response = res.body.string();

// ========== 处理响应 ==========
if (res.statusCode == 200) {
  toast("✅ 邮件发送成功！");
  console.log("响应:", response);
} else {
  toast("❌ 邮件发送失败");
  console.log("状态码:", res.statusCode);
  console.log("错误信息:", response);
}

Are you using K6 as the engine?

In general, your code looks fine, but most likely it should be:

var res = http.post(url, JSON.stringify(data), { headers });

This matches the typical K6 syntax for including headers.
