Webhooks

Webhooks allow you to send bot message events to external services for processing.

Configure Webhooks

1. In LangBot WebUI, click "API Integration" in the sidebar
2. Switch to the "Webhooks" tab
3. Click "+" to create a new webhook
4. Fill in:
   • Name: Webhook identifier
   • URL: Target URL to receive events
   • Description: Optional
   • Status: Enable or disable

Event Format

Person Message (bot.person_message)

{
  "uuid": "event-unique-id",
  "event_type": "bot.person_message",
  "data": {
    "bot_uuid": "bot-uuid",
    "adapter_name": "AdapterName",
    "sender": {
      "id": "user-id",
      "name": "User Name"
    },
    "message": [
      {
        "type": "Plain",
        "text": "Message content"
      }
    ],
    "timestamp": 1234567890
  }
}

Group Message (bot.group_message)

{
  "uuid": "event-unique-id",
  "event_type": "bot.group_message",
  "data": {
    "bot_uuid": "bot-uuid",
    "adapter_name": "AdapterName",
    "group": {
      "id": "group-id",
      "name": "Group Name"
    },
    "sender": {
      "id": "user-id",
      "name": "User Name"
    },
    "message": [
      {
        "type": "Plain",
        "text": "Message content"
      }
    ],
    "timestamp": 1234567890
  }
}

Response Format

Webhook services should return JSON:

{
  "status": "ok",
  "skip_pipeline": false
}

Parameters

• status: Processing status (recommend "ok")
• skip_pipeline: Whether to skip LangBot pipeline processing
  • true: Message won't continue in pipeline
  • false: Message proceeds normally

Tip

skip_pipeline lets you completely take over message processing. When true, the message is only handled by your webhook service and won't trigger LangBot's AI features.

Integration Example

Dify Workflow

Use the dify-plugin-langbot-trigger plugin to receive LangBot webhook events and create workflows in Dify.

Notes

• Webhook URL must be accessible
• Request timeout: 15 seconds
• Failed requests don't affect normal processing
• Multiple webhooks execute in parallel
• Any webhook returning skip_pipeline: true skips pipeline processing
