# WhatsApp Notification Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Add a WhatsApp notification to the dashcam transfer script that sends a summary to admin Eddy after each transfer.

**Architecture:** A single `send_whatsapp_notification()` function is added to `dashcam-transfer.py`. It POSTs to the local wwebjs-api (running on Mac Mini via Tailscale) using stdlib `urllib.request`. Failures are logged but never crash the script.

**Tech Stack:** Python 3 stdlib (`urllib.request`, `json`), wwebjs-api REST API

---

### Task 1: Add WhatsApp notification to dashcam-transfer.py

**Files:**
- Modify: `dashcam-transfer.py:3` (add imports)
- Modify: `dashcam-transfer.py:189-191` (add notification call)

- [ ] **Step 1: Add imports**

Add `import json` and `import urllib.request` after the existing stdlib imports.

- [ ] **Step 2: Add `send_whatsapp_notification()` function**

Insert before `parse_args()` (after `ensure_free_space`):

```python
WHATSAPP_API = "http://100.97.199.84:3000/client/sendMessage/EdGpt"
WHATSAPP_CHAT = "31620248011@c.us"


def send_whatsapp_notification(ok, errors):
    status = "geen fouten" if errors == 0 else f"{errors} fout(en)"
    body = f"Dashcam transfer voltooid: {ok} bestanden overgezet, {status}"
    payload = {"chatId": WHATSAPP_CHAT, "content": body, "contentType": "string"}
    try:
        data = json.dumps(payload).encode()
        req = urllib.request.Request(WHATSAPP_API, data=data, headers={"Content-Type": "application/json"})
        urllib.request.urlopen(req, timeout=10)
        logging.info("WhatsApp notificatie verstuurd")
    except Exception as e:
        logging.warning("WhatsApp notificatie mislukt: %s", e)
```

- [ ] **Step 3: Call notification at end of `main()`**

Replace:
```python
    logging.info(
        "Transfer voltooid: %d ok, %d fouten", ok, errors
    )
```

With:
```python
    logging.info("Transfer voltooid: %d ok, %d fouten", ok, errors)
    send_whatsapp_notification(ok, errors)
```

- [ ] **Step 4: Verify the script parses correctly**

Run: `python3 -c "import ast; ast.parse(open('dashcam-transfer.py').read()); print('OK')"`
Expected: `OK`

- [ ] **Step 5: Commit**

```bash
git add dashcam-transfer.py
git commit -m "feat: stuur WhatsApp notificatie na dashcam transfer"
```
