Stage 13 — Notifications: Telegram bot + multi-channel + service reminders
Schema:
- clients.telegram_chat_id (linked via /start contact-share)
- clients.notify_prefs (per-client channel order override)
- service_reminders_sent (dedup ledger for the daily cron)
Telegram (per tenant):
- TelegramService (sendMessage, getMe, setWebhook with auto-generated secret)
- Bot token stored in companies.settings.telegram.bot_token
- Webhook /telegram/webhook/{slug} validates X-Telegram-Bot-Api-Secret-Token,
matches client by last 9 digits of phone, persists chat_id, replies confirm
- /start prompts share-contact; /stop unlinks chat_id
NotificationDispatcher refactor:
- Multi-channel: telegram first if chat_id + bot configured, then email
- Backwards-compat with legacy boolean notify.{type} flags
- 4 HTML-formatted Telegram messages (wo_ready with tracking link, payment,
appointment, reminder)
Service reminders:
- `reminders:send` artisan command with --slug / --dry-run
- Policy: vehicles whose last closed WO is older than reminder.after_days
(default 365). Skips if sent within reminder.cooldown_days (default 30).
- Schedule daily 09:00
Filament UI:
- Settings page: Telegram bot token field + "Test bot" + "Set webhook" actions
- Settings page: reminder_after_days + reminder_cooldown_days inputs
- ClientResource: telegram_chat_id readonly badge
Tests (6 new, all pass):
- webhook links client via shared contact
- webhook rejects wrong secret → 401
- dispatcher uses telegram when chat_id present (Http::fake)
- dispatcher falls back to email otherwise
- dispatcher returns false when no channel available
- reminder cron respects 30-day cooldown
