# OpeniLink Hub — WeChat Bot Management Platform

> Skill by [ara.so](https://ara.so) — Daily 2026 Skills collection.

OpeniLink Hub is an open-source self-hosted platform for managing WeChat bots via the official **iLink (智联) protocol** introduced with WeChat ClawBot in March 2026. It handles context_token lifecycle, CDN encryption, 24-hour session renewal, multi-bot management, and message dispatch — so you focus on your business logic.

SDK Usage

Go SDK

go get github.com/openilink/openilink-sdk-go

package main

import (
    "context"
    "fmt"
    "log"

    openilink "github.com/openilink/openilink-sdk-go"
)

func main() {
    client := openilink.NewClient(openilink.Config{
        HubURL: "http://localhost:9800",
        Token:  os.Getenv("OPENILINK_TOKEN"),
    })

    // Listen for incoming messages via WebSocket
    err := client.OnMessage(context.Background(), func(msg *openilink.Message) error {
        fmt.Printf("[%s] %s: %s\n", msg.BotID, msg.Sender, msg.Content)

        // Reply to the message
        return client.SendText(context.Background(), &openilink.SendTextRequest{
            BotID:    msg.BotID,
            ToUserID: msg.Sender,
            Content:  "收到你的消息: " + msg.Content,
        })
    })
    if err != nil {
        log.Fatal(err)
    }
}

Node.js SDK

npm install @openilink/openilink-sdk-node

import { OpeniLinkClient } from '@openilink/openilink-sdk-node';

const client = new OpeniLinkClient({
  hubUrl: 'http://localhost:9800',
  token: process.env.OPENILINK_TOKEN,
});

// Subscribe to messages
client.onMessage(async (msg) => {
  console.log(`[${msg.botId}] ${msg.sender}: ${msg.content}`);

  // Send a reply
  await client.sendText({
    botId: msg.botId,
    toUserId: msg.sender,
    content: `Echo: ${msg.content}`,
  });
});

await client.connect();

Python SDK

pip install openilink-sdk-python

import os
import asyncio
from openilink import OpeniLinkClient

async def main():
    client = OpeniLinkClient(
        hub_url="http://localhost:9800",
        token=os.environ["OPENILINK_TOKEN"],
    )

    @client.on_message
    async def handle(msg):
        print(f"[{msg.bot_id}] {msg.sender}: {msg.content}")
        await client.send_text(
            bot_id=msg.bot_id,
            to_user_id=msg.sender,
            content=f"你好，我收到了: {msg.content}",
        )

    await client.connect()

asyncio.run(main())

Webhook Configuration

Configure a Webhook endpoint in the Hub dashboard under Settings → Webhooks. Hub will POST events to your URL:

{
  "event": "message.received",
  "bot_id": "bot_abc123",
  "message": {
    "id": "msg_xyz",
    "sender": "user_openid",
    "content": "Hello",
    "type": "text",
    "timestamp": 1711900800
  }
}

Express.js webhook handler

import express from 'express';
import crypto from 'crypto';

const app = express();
app.use(express.json());

app.post('/webhook', (req, res) => {
  // Verify Hub signature
  const sig = req.headers['x-openilink-signature'];
  const expected = crypto
    .createHmac('sha256', process.env.WEBHOOK_SECRET)
    .update(JSON.stringify(req.body))
    .digest('hex');

  if (sig !== `sha256=${expected}`) {
    return res.status(401).json({ error: 'Invalid signature' });
  }

  const { event, bot_id, message } = req.body;

  if (event === 'message.received') {
    console.log(`Bot ${bot_id} received: ${message.content}`);
    // process message...
  }

  res.json({ ok: true });
});

app.listen(8080);

Go webhook handler

package main

import (
    "crypto/hmac"
    "crypto/sha256"
    "encoding/hex"
    "encoding/json"
    "fmt"
    "net/http"
    "os"
)

type WebhookEvent struct {
    Event   string  `json:"event"`
    BotID   string  `json:"bot_id"`
    Message Message `json:"message"`
}

type Message struct {
    ID        string `json:"id"`
    Sender    string `json:"sender"`
    Content   string `json:"content"`
    Type      string `json:"type"`
    Timestamp int64  `json:"timestamp"`
}

func webhookHandler(w http.ResponseWriter, r *http.Request) {
    var body []byte
    body, _ = io.ReadAll(r.Body)

    // Verify signature
    sig := r.Header.Get("X-OpeniLink-Signature")
    mac := hmac.New(sha256.New, []byte(os.Getenv("WEBHOOK_SECRET")))
    mac.Write(body)
    expected := "sha256=" + hex.EncodeToString(mac.Sum(nil))
    if sig != expected {
        http.Error(w, "Unauthorized", http.StatusUnauthorized)
        return
    }

    var event WebhookEvent
    if err := json.Unmarshal(body, &event); err != nil {
        http.Error(w, "Bad Request", http.StatusBadRequest)
        return
    }

    if event.Event == "message.received" {
        fmt.Printf("Bot %s received from %s: %s\n",
            event.BotID, event.Message.Sender, event.Message.Content)
    }

    w.Header().Set("Content-Type", "application/json")
    w.Write([]byte(`{"ok":true}`))
}

func main() {
    http.HandleFunc("/webhook", webhookHandler)
    http.ListenAndServe(":8080", nil)
}

Building a Custom App

Apps integrate with Hub via WebSocket or Webhook and are authorized via PKCE OAuth.

Minimal Go App (based on openilink-app-echo)

git clone https://github.com/openilink/openilink-app-echo.git my-app
cd my-app

// main.go
package main

import (
    "context"
    "log"
    "os"

    app "github.com/openilink/openilink-app-sdk-go"
)

func main() {
    a := app.New(app.Config{
        AppID:     os.Getenv("APP_ID"),
        AppSecret: os.Getenv("APP_SECRET"),
        HubURL:    os.Getenv("HUB_URL"),
    })

    // Declare a command: users type /ping in WeChat
    a.RegisterCommand("ping", "Reply with pong", func(ctx context.Context, req *app.CommandRequest) error {
        return req.Reply("pong 🏓")
    })

    // Handle all messages
    a.OnMessage(func(ctx context.Context, msg *app.Message) error {
        log.Printf("Received: %s", msg.Content)
        return nil
    })

    if err := a.Start(context.Background()); err != nil {
        log.Fatal(err)
    }
}

App manifest (

app.json

{
  "id": "my-awesome-app",
  "name": "My Awesome App",
  "version": "1.0.0",
  "description": "Does something great with WeChat messages",
  "webhook_url": "https://my-app.example.com/webhook",
  "commands": [
    {
      "name": "ping",
      "description": "Replies with pong"
    }
  ],
  "scopes": ["messages:read", "messages:write"]
}

Local Development with Mock Server

# Terminal 1: Start Mock Server (no real WeChat needed)
go run ./cmd/appmock --webhook-url http://localhost:8080/webhook

# Terminal 2: Run your App
APP_ID=test APP_SECRET=test HUB_URL=http://localhost:9801 go run .

# Terminal 3: Inject a test message
curl -X POST http://localhost:9801/mock/event \
  -H "Content-Type: application/json" \
  -d '{"sender":"alice","content":"/ping"}'

# Check what your App sent back
curl http://localhost:9801/mock/messages

AI Auto-Reply Configuration

In the Hub dashboard → Settings → AI:

# Set via env or dashboard
OPENAI_API_KEY=...        # Set in environment
OPENAI_BASE_URL=...       # For compatible APIs (Ollama, DeepSeek, etc.)
OPENAI_MODEL=gpt-4o-mini
AI_SYSTEM_PROMPT="You are a helpful WeChat assistant."

Compatible with any OpenAI-spec API (Ollama, DeepSeek, Qwen, etc.).

REST API Patterns

Hub exposes a REST API at

http://localhost:9800/api/v1

# List connected bots
curl -H "Authorization: Bearer $OPENILINK_TOKEN" \
  http://localhost:9800/api/v1/bots

# Send a text message
curl -X POST \
  -H "Authorization: Bearer $OPENILINK_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"bot_id":"bot_abc","to_user_id":"user_openid","content":"Hello!"}' \
  http://localhost:9800/api/v1/messages/send

# Send an image
curl -X POST \
  -H "Authorization: Bearer $OPENILINK_TOKEN" \
  -F "bot_id=bot_abc" \
  -F "to_user_id=user_openid" \
  -F "image=@/path/to/image.png" \
  http://localhost:9800/api/v1/messages/send-image

# Get message trace (debugging)
curl -H "Authorization: Bearer $OPENILINK_TOKEN" \
  http://localhost:9800/api/v1/messages/trace/msg_xyz

Common Patterns

Pattern: Forward WeChat messages to Slack

Install the Bridge app from the marketplace, configure:

BRIDGE_TARGET=slack
SLACK_WEBHOOK_URL=https://hooks.slack.com/services/...
BRIDGE_BOT_ID=bot_abc123   # which bot to bridge

Pattern: Multi-bot message routing

client.OnMessage(context.Background(), func(msg *openilink.Message) error {
    switch msg.BotID {
    case "bot_customer_service":
        return handleCustomerService(msg)
    case "bot_sales":
        return handleSales(msg)
    default:
        return handleDefault(msg)
    }
})

Pattern: Command parsing in webhook

@client.on_message
async def handle(msg):
    if msg.content.startswith("/"):
        parts = msg.content.split(maxsplit=1)
        cmd = parts[0][1:]   # strip leading /
        args = parts[1] if len(parts) > 1 else ""

        if cmd == "help":
            await client.send_text(
                bot_id=msg.bot_id,
                to_user_id=msg.sender,
                content="Commands: /help /status /ping"
            )
        elif cmd == "ping":
            await client.send_text(
                bot_id=msg.bot_id,
                to_user_id=msg.sender,
                content="pong!"
            )

Troubleshooting

Bot shows offline / session expired

• Hub auto-renews 24-hour iLink sessions. If a bot goes offline, check Dashboard → Bots → Status.
• Re-scan QR code from the bot detail page.
• Check logs:

  journalctl -u openilink-hub -f

  (if installed as service).

Messages not delivered to Webhook

• Check Dashboard → Messages → Trace for the message — shows each delivery step with latency.
• Verify webhook URL is reachable from Hub (especially in Docker: use

  host.docker.internal

  not

  localhost

  ).
• Confirm

  WEBHOOK_SECRET

  matches on both sides.

Passkey login not working

• RP_ORIGIN

  must exactly match the browser URL (including port), e.g.

  https://hub.example.com

  .

• RP_ID

  must be the domain only, e.g.

  hub.example.com

  .
• Passkey requires HTTPS in production (localhost is exempt).

App OAuth flow fails

• Ensure App's redirect URI is registered in Hub dashboard under Apps → OAuth Settings.
• PKCE is required —

  code_challenge_method

  must be

  S256

  .

Docker networking: App can't reach Hub

# Use service name, not localhost
environment:
  HUB_URL: http://hub:9800

Database migration issues (PostgreSQL)

# Hub runs migrations automatically on start.
# To reset (destructive!):
docker compose down -v
docker compose up -d
