👤 Human-in-the-Loop (Approval Flow)

Kenapa Perlu Approval?

Tanpa approval: AI auto-send reply → bisa salah → rugi reputasi
Dengan approval: AI draft reply → human review → approve/reject → send

Wait Node = Pause Workflow

[Webhook: New Inquiry]
    → [AI Node: Draft Reply]
    → [Slack: Send draft for approval]
    → [Wait Node: Wait for Webhook (approval/rejection)]
        ├── Approved → [Send WhatsApp: Reply to customer]
        └── Rejected → [Slack: Log rejection + reason]

Wait Node Config

Node: Wait
- Mode: Webhook
- Path: approval-callback
- Resume: on webhook call

Webhook URL: https://[n8n]/webhook/approval-callback

Approval Interface Options

Option A: Slack Button (Simplest)

Slack message dengan button:
┌─────────────────────────────────┐
│ 📩 New Inquiry dari Budi        │
│ "Mau tanya harga produk X"      │
│                                 │
│ AI Draft Reply:                 │
│ "Halo Budi, harga produk X..." │
│                                 │
│ [✅ Approve] [❌ Reject]        │
└─────────────────────────────────┘

Option B: Simple Web Page

⚡ Pro Tips

1. Set timeout di Wait Node — jangan biar wait selamanya. 24 jam timeout, lalu auto-reject.
2. Log semua approval decisions — audit trail.
3. Escalation path — kalau ga di-approve dalam X jam → notif ke level atas.
4. Default action — kalau timeout, apa yang terjadi? Approve atau reject?
