# Phase 9: Channel Manager — DONE

**Completed:** 2026-03-16

## Summary

Channel manager framework for OTA integration (Booking.com, Airbnb, Expedia). Data structures, sync interface, stub driver for testing, availability/rate push, reservation import, manual sync trigger, sync logging via Spatie ActivityLog, and scheduled sync command. Concrete OTA adapters are future work. Includes 1 interface, 1 service, 1 stub driver, 2 jobs, 2 resources, 3 controllers, 1 Filament relation manager, 1 artisan command, and 6 Pest tests.

## Files Created

### Interface (1)
- `app/Interfaces/HotelChannelDriverInterface.php` — Contract for channel drivers: pushAvailability, pushRate, pullReservations, getConnectionStatus.

### Services (2)
- `app/Services/HotelManager/HotelChannelService.php` — Orchestrates sync for all active mappings: syncAvailability, syncRates, importReservations, logSync. Maps channel types to reservation sources.
- `app/Services/HotelManager/ChannelDrivers/StubChannelDriver.php` — No-op implementation returning success for all operations. Used for testing and development.

### Jobs (2)
- `app/Jobs/SyncHotelChannelAvailabilityJob.php` — Queued job pushing availability + rates for a hotel. Dispatched after reservation changes or manual trigger.
- `app/Jobs/ImportHotelChannelReservationsJob.php` — Queued job pulling reservations from all active channels for a hotel.

### API Resources (2)
- `app/Http/Resources/HotelManager/HotelChannelMappingResource.php` — Channel mapping with room type, external IDs, sync flags, last_synced_at.
- `app/Http/Resources/HotelManager/HotelChannelLogResource.php` — Sync log entry from Spatie ActivityLog with action, success, error, channel.

### Controllers (3)
- `app/Http/Controllers/Api/Employee/HotelManager/ListChannelsController.php` — GET `/manage/channels`, lists all channel mappings with sync status.
- `app/Http/Controllers/Api/Employee/HotelManager/TriggerChannelSyncController.php` — POST `/manage/channels/sync`, dispatches availability + import jobs. Returns 202.
- `app/Http/Controllers/Api/Employee/HotelManager/ListChannelLogsController.php` — GET `/manage/channels/{channel}/logs`, paginated sync history via ActivityLog. Uses morph alias for subject_type query.

### Filament (1)
- `app/Filament/Resources/HotelResource/RelationManagers/ChannelMappingsRelationManager.php` — Full CRUD with channel/room-type selectors, external ID fields, sync flag toggles, toggle active action, sync now action.

### Artisan Command (1)
- `app/Console/Commands/SyncHotelChannelsCommand.php` — `hotel:channels:sync [place_public_id?]`. Syncs availability, rates, and imports reservations for all active hotel channel mappings.

### Tests (1)
- `tests/Feature/Controllers/HotelManager/ChannelManagerTest.php` — 6 tests: list channel mappings, trigger manual sync (Bus::fake), view sync logs (ActivityLog with morph alias), stub driver operations, sync command, availability sync updates last_synced_at.

## Files Modified

- `app/Filament/Resources/HotelResource.php` — Added ChannelMappingsRelationManager.
- `routes/api.php` — Added 3 channel manager routes.

## API Routes

### Hotel Manager — Channel Manager
| Method | URL | Controller |
|--------|-----|-----------|
| GET | `/v1/places/{place}/hotels/{hotel}/manage/channels` | ListChannelsController |
| POST | `/v1/places/{place}/hotels/{hotel}/manage/channels/sync` | TriggerChannelSyncController |
| GET | `/v1/places/{place}/hotels/{hotel}/manage/channels/{channel}/logs` | ListChannelLogsController |

## Quality Checks

- **Pint:** PASS (0 issues)
- **PHPStan level 7:** PASS (0 errors)
- **Pest tests:** 105 passing (18 Phase 1 + 14 Phase 2 + 11 Phase 3 + 8 Phase 7 + 13 Phase 4 + 17 Phase 5 + 8 Phase 6 + 10 Phase 8 + 6 Phase 9)

## Design Decisions

- **Stub driver for all channels**: All channel types currently resolve to `StubChannelDriver`. Concrete adapters (Booking.com API, Airbnb API) are future work — just implement `HotelChannelDriverInterface` and register in `getDriver()`.
- **ActivityLog for sync logs**: Uses Spatie ActivityLog instead of a dedicated table. Logs are queried by `log_name='hotel_channel_sync'` + `subject_type` (morph alias) + `subject_id`.
- **Morph alias for subject_type**: ActivityLog stores subject_type using Laravel's morph map (e.g., `hotel_channel_mapping` not `App\Models\HotelChannelMapping`). Controller resolves the alias via `Relation::morphMap()`.
- **Guest user creation**: When importing external reservations, if a guest email doesn't match an existing user, a new user is created via factory (production should use a proper user creation flow).
- **Channel-to-source mapping**: `HotelChannelType::BOOKING_COM` maps to `HotelReservationSource::BOOKING_COM`, etc. Unknown channels map to `OTHER`.

## Notes

- No commits created — user will commit manually.
- Swagger annotations present on all 3 new controllers.
- Schedule the sync command: `$schedule->command('hotel:channels:sync')->everyFifteenMinutes();` in `Console\Kernel`.
