Webhooks（接收）

当 SupDesk 项目中发生事件时，出站 Webhooks 会向您配置的端点发送 HTTP POST 请求。本页面记录了载荷格式、签名机制和重试行为，以便您构建可靠的 Webhook 接收器。

载荷格式

每次 Webhook 投递使用标准信封：


{
  "event": "post.created",
  "timestamp": "2026-07-15T12:00:00.000Z",
  "project_id": "550e8400-e29b-41d4-a716-446655440000",
  "data": { ... }
}

字段	类型	描述
`event`	string	触发投递的事件
`timestamp`	string	事件发生时的 ISO 8601 时间戳
`project_id`	string	事件发生的项目 UUID
`data`	object	事件特定的载荷（见下文）

签名验证

每次投递包含一个 X-SupDesk-Signature 头：


X-SupDesk-Signature: sha256=a1b2c3d4e5f6...

sha256= 之后的值是使用 Webhook 签名密钥计算的请求体原始数据的十六进制编码 HMAC-SHA256。

验证步骤

读取请求体原始数据（不要先解析 JSON）
计算 HMAC-SHA256(签名密钥, 原始数据)
将十六进制摘要与签名头中的值进行比较
使用恒定时间比较以防止时序攻击

Node.js 示例


import { createHmac, timingSafeEqual } from "crypto";
 
function verifySupDeskWebhook(secret, rawBody, signatureHeader) {
  const expected = createHmac("sha256", secret)
    .update(rawBody)
    .digest("hex");
  const received = signatureHeader.replace("sha256=", "");
  return timingSafeEqual(Buffer.from(expected), Buffer.from(received));
}
 
// Express example
app.post("/webhooks/supdesk", express.raw({ type: "application/json" }), (req, res) => {
  const sig = req.headers["x-supdesk-signature"];
  if (!verifySupDeskWebhook(SECRET, req.body, sig)) {
    return res.status(401).json({ error: "Invalid signature" });
  }
  const event = JSON.parse(req.body);
  // Process event...
  res.status(200).json({ ok: true });
});

Python 示例


import hmac
import hashlib
from flask import Flask, request, jsonify
 
app = Flask(__name__)
WEBHOOK_SECRET = "your-signing-secret"
 
def verify_signature(secret: str, body: bytes, header: str) -> bool:
    expected = hmac.new(secret.encode(), body, hashlib.sha256).hexdigest()
    received = header.removeprefix("sha256=")
    return hmac.compare_digest(expected, received)
 
@app.route("/webhooks/supdesk", methods=["POST"])
def handle_webhook():
    sig = request.headers.get("X-SupDesk-Signature", "")
    if not verify_signature(WEBHOOK_SECRET, request.data, sig):
        return jsonify(error="Invalid signature"), 401
    event = request.get_json()
    # Process event...
    return jsonify(ok=True), 200

Ruby 示例


require "openssl"
require "sinatra"
require "json"
 
WEBHOOK_SECRET = "your-signing-secret"
 
def verify_signature(secret, body, header)
  expected = OpenSSL::HMAC.hexdigest("SHA256", secret, body)
  received = header.sub("sha256=", "")
  Rack::Utils.secure_compare(expected, received)
end
 
post "/webhooks/supdesk" do
  body = request.body.read
  sig = request.env["HTTP_X_SUPDESK_SIGNATURE"] || ""
  unless verify_signature(WEBHOOK_SECRET, body, sig)
    halt 401, { error: "Invalid signature" }.to_json
  end
  event = JSON.parse(body)
  # Process event...
  status 200
  { ok: true }.to_json
end

重试

当 Webhook 投递失败时，SupDesk 以指数退避方式重试：

尝试	延迟
1	立即
2	1 秒
3	2 秒

重试条件： 5xx 响应、网络错误、超时（10 秒）。

不重试： 4xx 响应（客户端错误表示配置问题）。

响应 Webhook

返回 2xx 状态码以确认收到
在 10 秒内响应以避免超时重试
如果逻辑耗时较长，请异步处理事件
对于重复投递返回相同响应（幂等性）
