# Phase 6 Implementation Summary
|
||||
|
||||
## Overview
|
||||
Phase 6 implementation adds webhook support and remote control capabilities, allowing IGNY8 SaaS to send events to WordPress.
|
||||
|
||||
## Implemented Features
|
||||
|
||||
### 6.1 REST Route Registration with Shared Secret ✅
|
||||
|
||||
**Files Created:**
|
||||
- `includes/class-igny8-webhooks.php` - Main webhook handler class
|
||||
|
||||
**Features:**
|
||||
- **REST Endpoint**: `/wp-json/igny8/v1/event` (POST)
|
||||
- **Shared Secret Authentication**: HMAC-SHA256 signature verification
|
||||
- **Connection Check**: All webhook handlers verify `igny8_is_connection_enabled()` before processing
|
||||
|
||||
**Security:**
|
||||
- Webhook secret stored in WordPress options (auto-generated on first use)
|
||||
- Signature verification via `X-IGNY8-Signature` header
|
||||
- Secret can be regenerated from settings page
|
||||
- Failed authentication attempts are logged
|
||||
|
||||
**Functions:**
|
||||
- `igny8_get_webhook_secret()` - Get or generate webhook secret
|
||||
- `igny8_regenerate_webhook_secret()` - Regenerate secret
|
||||
|
||||

|
||||
|
||||
### 6.2 SaaS Event Handlers ✅
|
||||
|
||||
**Event Types Supported:**
|
||||
|
||||
#### 1. Task Published (`task_published`, `task_completed`)
|
||||
- Creates or updates WordPress post from IGNY8 task
|
||||
- Fetches full task data from Writer API
|
||||
- Respects enabled post types
|
||||
- Updates post status if task is completed
|
||||
|
||||
#### 2. Link Recommendation (`link_recommendation`, `insert_link`)
|
||||
- Queues link insertion for processing
|
||||
- Validates required parameters (post_id, target_url, anchor)
|
||||
- Respects Linker module toggle
|
||||
- Processes links asynchronously via cron
|
||||
|
||||
#### 3. Optimizer Request (`optimizer_request`, `optimizer_job_completed`)
|
||||
- Updates optimizer job status
|
||||
- Stores score changes and recommendations
|
||||
- Updates post meta with optimizer data
|
||||
- Respects Optimizer module toggle
|
||||
|
||||
**Event Handler Flow:**
|
||||
1. Verify connection is enabled
|
||||
2. Verify module is enabled (if applicable)
|
||||
3. Validate event data
|
||||
4. Process event
|
||||
5. Log activity
|
||||
6. Return unified JSON response
|
||||

|
||||
|
||||
### 6.3 Webhook Activity Logging ✅
|
||||
|
||||
**Files Created:**
|
||||
- `includes/class-igny8-webhook-logs.php` - Logging functions
|
||||
|
||||
**Features:**
|
||||
- **Log Storage**: WordPress options (last 500 logs)
|
||||
- **Log Fields**:
|
||||
- Event type
|
||||
- Event data
|
||||
- IP address
|
||||
- User agent
|
||||
- Status (received, processed, failed)
|
||||
- Response data
|
||||
- Timestamps (received_at, processed_at)
|
||||
- Error messages
|
||||
|
||||
**Functions:**
|
||||
- `igny8_log_webhook_activity()` - Log webhook receipt
|
||||
- `igny8_update_webhook_log()` - Update log with processing result
|
||||
- `igny8_get_webhook_logs()` - Retrieve logs with filtering
|
||||
- `igny8_clear_old_webhook_logs()` - Cleanup old logs
|
||||
|
||||
**UI Display:**
|
||||
- Recent webhook activity table in settings page
|
||||
- Shows last 10 webhook events
|
||||
- Displays event type, status, and timestamp
|
||||
|
||||

|
||||
|
||||
### Link Queue System ✅
|
||||
|
||||
**Files Created:**
|
||||
- `includes/class-igny8-link-queue.php` - Link insertion queue
|
||||
|
||||
**Features:**
|
||||
- **Queue Storage**: WordPress options
|
||||
- **Queue Processing**: Cron-based (processes 10 items per run)
|
||||
- **Retry Logic**: Up to 3 attempts per link
|
||||
- **Status Tracking**: pending, completed, failed
|
||||
|
||||
**Link Insertion Logic:**
|
||||
1. Finds anchor text in post content
|
||||
2. Wraps anchor with link tag
|
||||
3. Avoids duplicate links
|
||||
4. Falls back to appending link if anchor not found
|
||||
|
||||
**Queue Management:**
|
||||
- Automatic processing via cron
|
||||
- Manual trigger available
|
||||
- Queue size limit (1000 items)
|
||||
- Status tracking per item
|
||||

|
||||
|
||||
## Connection Checks
|
||||
|
||||
**All handlers check connection status:**
|
||||
|
||||
✅ **Webhook Handler** (`verify_webhook_secret`)
|
||||
- Checks `igny8_is_connection_enabled()` before allowing webhook
|
||||
|
||||
✅ **Event Handlers** (`handle_webhook`, `handle_task_published`, etc.)
|
||||
- Double-checks connection enabled before processing
|
||||
- Returns error if connection disabled
|
||||
|
||||
✅ **Link Queue** (`igny8_queue_link_insertion`, `igny8_process_link_queue`)
|
||||
- Checks connection enabled before queuing/processing
|
||||
|
||||
✅ **REST API Endpoints** (existing endpoints)
|
||||
- Updated to check connection enabled
|
||||
- Returns 403 if connection disabled
|
||||

## Notes
|
||||
|
||||
1. **Webhook Secret**: Auto-generated on first use. Must be configured in IGNY8 SaaS app.
|
||||
|
||||
2. **Link Queue**: Processes 10 items per cron run to prevent timeouts. Can be adjusted.
|
||||
|
||||
3. **Log Retention**: Keeps last 500 logs. Older logs can be cleared manually.
|
||||
|
||||
4. **Signature Header**: IGNY8 SaaS must send `X-IGNY8-Signature` header with HMAC-SHA256 signature of request body.
|
||||
|
||||
5. **Connection Toggle**: All webhook handlers check connection status before processing. This ensures no data is processed when connection is disabled.
|
||||
|
||||
6. **Module Toggles**: Each event type checks if its module is enabled before processing.
