Smart Webhook Routing Logic

The Smart Webhook automatically routes messages based on event_name and message content:

| Event Type | Condition | Output | |------------|-----------|--------| | message.text.received | Text message | Output 0: Text Message | | message.image.received | Image with empty/null caption | Output 1: Photo Only | | message.image.received | Image with caption text | Output 2: Photo + Message | | message.sticker.received | Sticker message | Output 3: Sticker | | message.unsupported.received | Unsupported type | Output 4: Unsupported/Other | | Any other event | Fallback | Output 4: Unsupported/Other |

Message Structure:

{
  "event_name": "message.image.received",
  "message": {
    "caption": "Mẫu này còn không?",
    "photo_url": "https://...",
    "chat": { "id": "..." },
    "from": { "display_name": "..." }
  }
}
