Webhook Push Skill

Overview

This skill provides a unified interface for sending webhook notifications to three major Chinese enterprise communication platforms:

• WeCom (企业微信) - Enterprise WeChat by Tencent
• DingTalk (钉钉) - Enterprise communication platform by Alibaba
• Feishu (飞书) - Collaboration platform by ByteDance

When to Use This Skill

Use this skill when you need to:

• Send notifications to enterprise chat groups
• Integrate monitoring alerts into enterprise platforms
• Automate notifications for CI/CD pipelines
• Build incident management workflows
• Send reports and updates to team channels
• Create multi-platform notification systems

Core Capabilities

1. Unified Message Model

Send messages using a single, platform-agnostic interface:

from webhook_push import UnifiedMessage, MessageSender

message = UnifiedMessage(
    content={
        "type": "text",
        "body": {"text": "Deployment completed successfully!"}
    }
)

sender = MessageSender()
result = await sender.send(message, "dingtalk", webhook_url="https://oapi.dingtalk.com/robot/send?access_token=xxx")

2. Rich Message Types

Support for various message types:

• Text - Simple text messages with @mentions
• Markdown - Rich formatted messages
• Image - Send images (WeCom, Feishu)
• Link - Link cards (DingTalk)
• Card - Interactive cards with buttons
• File - File attachments (WeCom, Feishu)
• Feed - Multiple link cards (DingTalk)

3. Automatic Platform Conversion

Messages are automatically converted to platform-specific formats:

# Same message works across platforms
message = UnifiedMessage(
    content={
        "type": "markdown",
        "title": "Daily Report",
        "body": {
            "content": "# Daily Stats\n- Users: 128\n- Revenue: $5,000"
        }
    }
)

# Send to all platforms automatically
result = await sender.send_auto(message)

4. Graceful Degradation

Unsupported features are automatically downgraded:

• Cards → Markdown with links
• Markdown → Plain text
• Rich features → Simple alternatives

5. Retry Mechanism

Built-in exponential backoff retry logic handles transient failures.

Message Types

Text Message

message = UnifiedMessage(
    content={
        "type": "text",
        "body": {"text": "Hello, team!"},
        "mentions": [
            {"type": "mobile", "value": "13800000000", "display_name": "Zhang San"}
        ]
    }
)

Markdown Message

message = UnifiedMessage(
    content={
        "type": "markdown",
        "title": "Deployment Report",
        "body": {
            "content": """# Deployment Complete

## Status: ✅ Success
- Version: v1.2.3
- Environment: Production
- Deployed by: @zhangsan

[View Logs](https://example.com/logs)"""
        }
    }
)

            "title": "系统告警",
            "description": "CPU使用率超过阈值",
            "emphasis": {
                "title": "95%",
                "desc": "当前CPU使用率"
            },
            "horizontal_content_list": [
                {"keyname": "服务器", "value": "web-01"},
                {"keyname": "阈值", "value": "80%"}
            ],
            "jump_list": [
                {"type": 1, "url": "https://example.com/alerts", "title": "查看详情"}
            ],

Usage Patterns

Basic Pattern

from webhook_push import MessageSender, UnifiedMessage

# Create message
message = UnifiedMessage(
    content={
        "type": "text",
        "body": {"text": "Your notification message"}
    }
)

# Send to specific platform
sender = MessageSender()
result = await sender.send(
    message,
    "dingtalk",
    webhook_url="https://oapi.dingtalk.com/robot/send?access_token=YOUR_TOKEN"
)

if result.success:
    print("Sent!")
else:
    print(f"Failed: {result.error}")

Multi-Platform

# Send to multiple platforms
result = await sender.send_multi(
    message,
    platforms=["wecom", "dingtalk", "feishu"],
    webhook_urls={
        "wecom": "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=XXX",
        "dingtalk": "https://oapi.dingtalk.com/robot/send?access_token=YYY",
        "feishu": "https://open.feishu.cn/open-apis/bot/v2/hook/ZZZ"
    }
)

print(f"Success: {result.success_count}, Failed: {result.failed_count}")

Automatic Selection

# Send to all configured platforms
result = await sender.send_auto(message)

print(f"Sent to: {result.sent_platforms}")
print(f"Skipped: {result.skipped_platforms}")

Platform Configuration

Enterprise WeChat

# Via webhook URL
webhook_url = "https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=YOUR_KEY"

Best Practices

1. Use Markdown for Rich Content

Markdown provides the best compatibility across platforms:

message = UnifiedMessage(
    content={
        "type": "markdown",
        "body": {
            "content": """# Report

## Summary
- Metric 1: **128**
- Metric 2: 3,421

> Last updated: 18:00"""
        }
    }
)

2. Handle Failures Gracefully

result = await sender.send(message, "dingtalk", webhook_url)

if not result.success:
    if result.retry_suggested:
        # Retry later or queue for retry
        await retry_queue.add(message)
    else:
        # Log the error
        logger.error(f"Send failed: {result.error}")

3. Use Card Messages for Actions

Cards with buttons provide better user experience:

message = UnifiedMessage(
    content={
        "type": "card",
        "body": {
            "card_type": "interactive",
            "elements": [{"type": "div", "text": "Review required"}],
            "actions": [
                {"type": "button", "text": "Approve", "url": "...", "style": "primary"},
                {"type": "button", "text": "Reject", "url": "..."}
            ]
        }
    }
)

4. Monitor Rate Limits

Each platform has different rate limits:

The sender automatically handles rate limit errors.

Advanced Features

Custom Retry Policy

from webhook_push import MessageSender, RetryPolicy, SenderOptions

options = SenderOptions(
    retry_policy=RetryPolicy(
        max_retries=5,
        initial_delay=1000,
        max_delay=30000,
        backoff_multiplier=2.0
    )
)

sender = MessageSender(options)

Message Deduplication

Use message_id for deduplication:

message = UnifiedMessage(
    metadata={"message_id": "unique-id-123"},
    content={"type": "text", "body": {"text": "Same message"}}
)

Correlation Tracking

Use correlation_id to track related messages:

message = UnifiedMessage(
    metadata={"correlation_id": "deployment-123"},
    content={"type": "markdown", "body": {"content": "Deployment update"}}
)

Error Handling

Common error codes:

Performance Tips

1. Use send_multi for sending to multiple platforms
2. Use send_auto to leverage all available platforms
3. Configure timeouts for long-running operations
4. Monitor rate limits for high-volume scenarios
