1.3 Signed Webhook Requests

1.3 签名Webhook请求

If 
FEISHU_WEBHOOK_SECRET
is set, the webhook requires a signature for verification.
Generate a signed request:
bash
undefined
如果设置了
FEISHU_WEBHOOK_SECRET
，webhook请求需要携带签名以通过验证。
生成签名请求：
bash
undefined

Calculate timestamp and signature

计算时间戳和签名

TIMESTAMP=$(date +%s) STRING_TO_SIGN="${TIMESTAMP}\n${FEISHU_WEBHOOK_SECRET}" SIGN=$(printf '%b' "${STRING_TO_SIGN}" | openssl dgst -sha256 -hmac "" -binary | openssl base64)
TIMESTAMP=$(date +%s) STRING_TO_SIGN="${TIMESTAMP}\n${FEISHU_WEBHOOK_SECRET}" SIGN=$(printf '%b' "${STRING_TO_SIGN}" | openssl dgst -sha256 -hmac "" -binary | openssl base64)

For proper HMAC-SHA256 signing:

正确的HMAC-SHA256签名方式：

SIGN=$(echo -ne "${TIMESTAMP}\n${FEISHU_WEBHOOK_SECRET}" | openssl dgst -sha256 -hmac "" -binary | base64)
curl -s -X POST "${FEISHU_WEBHOOK_URL}"
-H "Content-Type: application/json"
-d "{ "timestamp": "${TIMESTAMP}", "sign": "${SIGN}", "msg_type": "text", "content": { "text": "Signed message from OpenClaudia." } }"

**Feishu signature algorithm details:**
1. Concatenate `timestamp + "\n" + secret` as the string to sign
2. Compute HMAC-SHA256 with an empty key over that string
3. Base64-encode the result
4. Include both `timestamp` and `sign` in the request JSON body

---
SIGN=$(echo -ne "${TIMESTAMP}\n${FEISHU_WEBHOOK_SECRET}" | openssl dgst -sha256 -hmac "" -binary | base64)
curl -s -X POST "${FEISHU_WEBHOOK_URL}"
-H "Content-Type: application/json"
-d "{ "timestamp": "${TIMESTAMP}", "sign": "${SIGN}", "msg_type": "text", "content": { "text": "Signed message from OpenClaudia." } }"

**Feishu签名算法细节：**
1. 将`timestamp + "\n" + secret`拼接为待签名字符串
2. 使用空密钥对字符串进行HMAC-SHA256计算
3. 将结果进行Base64编码
4. 在请求JSON体中同时包含`timestamp`和`sign`字段

5. Helper: Build and Send Cards Programmatically

5. 辅助工具：通过代码构建并发送卡片

For complex or dynamic cards, use Python to construct the JSON payload:
bash
python3 -c "
import json, subprocess, os

webhook_url = os.environ.get('FEISHU_WEBHOOK_URL', '')
if not webhook_url:
    print('Error: FEISHU_WEBHOOK_URL not set')
    exit(1)
对于复杂或动态卡片，使用Python构建JSON请求体：
bash
python3 -c "
import json, subprocess, os

webhook_url = os.environ.get('FEISHU_WEBHOOK_URL', '')
if not webhook_url:
    print('Error: FEISHU_WEBHOOK_URL not set')
    exit(1)

Build card dynamically

动态构建卡片

card = { 'msg_type': 'interactive', 'card': { 'header': { 'title': {'tag': 'plain_text', 'content': 'Dynamic Card Title'}, 'template': 'blue' }, 'elements': [] } }
card = { 'msg_type': 'interactive', 'card': { 'header': { 'title': {'tag': 'plain_text', 'content': 'Dynamic Card Title'}, 'template': 'blue' }, 'elements': [] } }

Add content blocks

添加内容区块

card['card']['elements'].append({ 'tag': 'markdown', 'content': 'This card was built programmatically.\n\nKey metrics:\n- Users: 10,000\n- Revenue: $50,000' })
card['card']['elements'].append({ 'tag': 'markdown', 'content': 'This card was built programmatically.\n\nKey metrics:\n- Users: 10,000\n- Revenue: $50,000' })

Add a divider

添加分隔线

card['card']['elements'].append({'tag': 'hr'})
card['card']['elements'].append({'tag': 'hr'})

Add buttons

添加按钮

card['card']['elements'].append({ 'tag': 'action', 'actions': [ { 'tag': 'button', 'text': {'tag': 'plain_text', 'content': 'Learn More'}, 'type': 'primary', 'url': 'https://example.com' } ] })
card['card']['elements'].append({ 'tag': 'action', 'actions': [ { 'tag': 'button', 'text': {'tag': 'plain_text', 'content': 'Learn More'}, 'type': 'primary', 'url': 'https://example.com' } ] })

Add footer

添加页脚

card['card']['elements'].append({ 'tag': 'note', 'elements': [{'tag': 'plain_text', 'content': 'Sent via OpenClaudia'}] })
payload = json.dumps(card) result = subprocess.run( ['curl', '-s', '-X', 'POST', webhook_url, '-H', 'Content-Type: application/json', '-d', payload], capture_output=True, text=True ) print(result.stdout) "

---
card['card']['elements'].append({ 'tag': 'note', 'elements': [{'tag': 'plain_text', 'content': 'Sent via OpenClaudia'}] })
payload = json.dumps(card) result = subprocess.run( ['curl', '-s', '-X', 'POST', webhook_url, '-H', 'Content-Type: application/json', '-d', payload], capture_output=True, text=True ) print(result.stdout) "

6. Bilingual Support (Chinese + English)

6. 双语支持（中文 + 英文）

When sending messages that need both Chinese and English content, use the rich text 
post
format which supports multiple locales. Feishu will display the locale matching the user's language setting.
bash
curl -s -X POST "${FEISHU_WEBHOOK_URL}" \
  -H "Content-Type: application/json" \
  -d '{
    "msg_type": "post",
    "content": {
      "post": {
        "zh_cn": {
          "title": "重要通知：系统维护",
          "content": [
            [
              {"tag": "text", "text": "我们将于 "},
              {"tag": "text", "text": "1月25日 22:00-02:00 (北京时间)", "un_escape": true},
              {"tag": "text", "text": " 进行系统维护。"}
            ],
            [
              {"tag": "text", "text": "维护期间服务将暂时不可用。如有问题请联系 "},
              {"tag": "a", "text": "技术支持", "href": "https://example.com/support"},
              {"tag": "text", "text": "。"}
            ]
          ]
        },
        "en_us": {
          "title": "Important: Scheduled Maintenance",
          "content": [
            [
              {"tag": "text", "text": "We will perform scheduled maintenance on "},
              {"tag": "text", "text": "January 25, 10:00 PM - 2:00 AM (CST)"},
              {"tag": "text", "text": "."}
            ],
            [
              {"tag": "text", "text": "Services will be temporarily unavailable. For questions, contact "},
              {"tag": "a", "text": "Support", "href": "https://example.com/support"},
              {"tag": "text", "text": "."}
            ]
          ]
        }
      }
    }
  }'
当需要发送中英文双语内容时，使用富文本
post
格式，该格式支持多语言环境。Feishu会根据用户的语言设置显示对应版本的内容。
bash
curl -s -X POST "${FEISHU_WEBHOOK_URL}" \
  -H "Content-Type: application/json" \
  -d '{
    "msg_type": "post",
    "content": {
      "post": {
        "zh_cn": {
          "title": "重要通知：系统维护",
          "content": [
            [
              {"tag": "text", "text": "我们将于 "},

            ],
            [
              {"tag": "text", "text": "维护期间服务将暂时不可用。如有问题请联系 "},

              {"tag": "text", "text": "。"}
            ]
          ]
        },
        "en_us": {
          "title": "Important: Scheduled Maintenance",
          "content": [

Common Troubleshooting

常见故障排查

Message not delivered:
  • Verify the webhook URL is correct and the bot is still in the group
  • Check that 
    msg_type
    matches the content structure
  • For signed webhooks, ensure the timestamp is within 1 hour of current time
Card not rendering:
  • Validate JSON structure: header and elements are both required
  • Button URLs must start with 
    http://
    or 
    https://
  • Markdown in cards supports a limited subset: bold, italic, links, lists, tables
API token errors:
  • Tenant access tokens expire after 2 hours; re-fetch before sending
  • Ensure the app has been published and approved in the developer console
  • Verify 
    im:message:send_as_bot
    permission is granted
消息未送达：
  • 验证webhook URL是否正确，且Bot仍在群组中
  • 检查
    msg_type
    是否与内容结构匹配
  • 对于签名webhook，确保时间戳与当前时间差不超过1小时
卡片未正常渲染：
  • 验证JSON结构：header和elements字段均为必填项
  • 按钮URL必须以
    http://
    或
    https://
    开头
  • 卡片中的Markdown仅支持有限子集：加粗、斜体、链接、列表、表格
API令牌错误：
  • 租户访问令牌有效期为2小时，发送前需重新获取
  • 确保应用已在开发者控制台发布并通过审核
  • 验证已授予
    im:message:send_as_bot
    权限

Tips

小贴士

  • Start with webhooks. Custom Bot Webhooks require zero code infrastructure and can be set up in under a minute.
  • Use interactive cards for anything beyond simple text. They are more readable and actionable.
  • Include action buttons in every marketing card. Drive recipients to a landing page, dashboard, or sign-up form.
  • Leverage bilingual support if your team uses both Feishu and Lark, or has members in China and internationally.
  • Respect rate limits. For bulk messaging (e.g., sending to multiple groups), add a 1-second delay between requests.
  • Test in a private group first before sending to large team channels.
  • Keep card content concise. Cards have a maximum content size of approximately 30KB. For very long reports, link to an external page.
  • Use the Feishu Message Card Builder for visual card design: https://open.feishu.cn/tool/cardbuilder (Feishu) or https://open.larksuite.com/tool/cardbuilder (Lark).
  • 从webhook开始：自定义Bot Webhook无需代码基础设施，可在1分钟内完成配置。
  • 使用互动卡片：除简单文本外，优先使用互动卡片，可读性和可操作性更强。
  • 添加操作按钮：在所有营销卡片中加入按钮，引导接收者访问落地页、仪表盘或注册表单。
  • 利用双语支持：如果团队同时使用Feishu和Lark，或成员分布在中国和海外，请提供双语内容。
  • 遵守频率限制：批量发送消息（如向多个群组发送）时，在请求之间添加1秒延迟。
  • 先在私有群组测试：向大型团队频道发送前，先在私有群组测试效果。
  • 保持卡片内容简洁：卡片最大内容约为30KB，对于超长报告，请链接到外部页面。
