| 1 | +# QRZ Log Export Feature - Implementation Complete |
| 2 | + |
| 3 | +## Overview |
| 4 | +This implementation adds comprehensive QRZ logbook synchronization functionality to the Nextlog amateur radio logging application. Users can now sync their logged QSOs with their QRZ.com logbook both manually and automatically. |
| 5 | + |
| 6 | +## Features Implemented |
| 7 | + |
| 8 | +### ✅ Core Functionality |
| 9 | +- **QRZ Logbook API Integration**: Full implementation using QRZ's POST-based logbook API |
| 10 | +- **ADIF Format Conversion**: Proper conversion of contacts to ADIF format for QRZ upload |
| 11 | +- **Authentication**: Uses existing encrypted QRZ credential storage |
| 12 | +- **Auto-sync**: Background sync on contact creation/update when enabled |
| 13 | +- **Manual Sync**: Individual contact sync and bulk selection sync |
| 14 | +- **Status Tracking**: Comprehensive sync status per contact |
| 15 | + |
| 16 | +### ✅ Database Schema |
| 17 | +- Added QRZ sync fields to contacts table: |
| 18 | + - `qrz_sync_status`: enum ('not_synced', 'synced', 'error', 'already_exists') |
| 19 | + - `qrz_sync_date`: timestamp of last sync attempt |
| 20 | + - `qrz_logbook_id`: QRZ logbook record ID if successfully synced |
| 21 | + - `qrz_sync_error`: error message for failed syncs |
| 22 | +- Added `qrz_auto_sync` setting to users table |
| 23 | + |
| 24 | +### ✅ API Endpoints |
| 25 | +- `/api/user/qrz/validate` - Validate QRZ logbook credentials |
| 26 | +- `/api/contacts/qrz-sync` - Bulk sync multiple contacts |
| 27 | +- `/api/contacts/[id]/qrz-sync` - Sync individual contact |
| 28 | +- Updated `/api/user/profile` to include auto-sync setting |
| 29 | + |
| 30 | +### ✅ UI Components |
| 31 | +- **QRZSyncIndicator**: Visual status indicator with tooltips and sync buttons |
| 32 | +- **Profile Page**: QRZ credential validation and auto-sync toggle |
| 33 | +- **Contacts Tables**: Added QRZ sync column to search and dashboard pages |
| 34 | +- **Bulk Operations**: Checkbox selection and bulk sync controls |
| 35 | +- **Error Handling**: Clear error messages and retry functionality |
| 36 | + |
| 37 | +### ✅ Error Handling & Conflict Resolution |
| 38 | +- Handles existing QSOs gracefully (marks as "already_exists") |
| 39 | +- Comprehensive error tracking and display |
| 40 | +- Retry functionality for failed syncs |
| 41 | +- Network error handling |
| 42 | + |
| 43 | +## Setup Instructions |
| 44 | + |
| 45 | +### 1. Database Migration |
| 46 | +Apply the QRZ sync schema changes: |
| 47 | +```sql |
| 48 | +-- Run the migration script |
| 49 | +\i scripts/add-qrz-sync-fields.sql |
| 50 | +``` |
| 51 | + |
| 52 | +### 2. Configure QRZ Credentials |
| 53 | +1. Go to Profile page |
| 54 | +2. Enter QRZ.com username and password |
| 55 | +3. Click "Validate Credentials" to test logbook access |
| 56 | +4. Enable "Auto-sync new contacts to QRZ logbook" if desired |
| 57 | + |
| 58 | +### 3. Usage |
| 59 | +**Manual Sync:** |
| 60 | +- Go to Search Contacts page |
| 61 | +- Select contacts using checkboxes |
| 62 | +- Click "Sync X to QRZ" button |
| 63 | +- Or click individual sync buttons on each contact |
| 64 | + |
| 65 | +**Auto Sync:** |
| 66 | +- Enable in Profile settings |
| 67 | +- New contacts will automatically sync in background |
| 68 | +- Updated contacts will re-sync if core fields change |
| 69 | + |
| 70 | +## Technical Implementation Details |
| 71 | + |
| 72 | +### QRZ Logbook API |
| 73 | +The implementation uses QRZ's logbook API (different from XML lookup API): |
| 74 | +- Endpoint: `https://logbook.qrz.com/api` |
| 75 | +- Authentication: POST with username/password |
| 76 | +- Upload: ADIF format via form data |
| 77 | +- Response: TEXT format with status codes |
| 78 | + |
| 79 | +### Auto-sync Logic |
| 80 | +- Triggers on contact create/update |
| 81 | +- Runs in background (non-blocking) |
| 82 | +- Only syncs if user has auto-sync enabled |
| 83 | +- Resets sync status when contact is modified |
| 84 | + |
| 85 | +### Status Management |
| 86 | +- `not_synced`: New contact, not yet synced |
| 87 | +- `synced`: Successfully uploaded to QRZ |
| 88 | +- `error`: Sync failed (see error message) |
| 89 | +- `already_exists`: QSO already in QRZ logbook |
| 90 | + |
| 91 | +### Security |
| 92 | +- Leverages existing encrypted credential storage |
| 93 | +- Credentials validated before use |
| 94 | +- Background operations handle auth failures gracefully |
| 95 | + |
