+# Autotask Webhook Setup Guide
+
+## Overview
+
+This guide explains how to configure Autotask webhooks for real-time data synchronization with Pulse. Webhooks provide near-instant updates when entities change in Autotask, reducing API calls and keeping your data fresh.
+
+---

+
+---
+
+## Benefits of Webhooks
+
+### **Real-Time Updates**
+- Instant notification when entities are created or updated in Autotask
+- No polling delay - changes appear within seconds
+
+### **Reduced API Usage**
+- Fewer API calls compared to frequent polling
+- Lower risk of hitting API rate limits
+- More efficient use of resources
+
+### **Better Data Freshness**
+- Combined with daily incremental syncs for redundancy
+- Ensures no events are missed
+- Automatic recovery from webhook failures
+
+---
+
+## Supported Entities
+
+The following entities support webhook notifications:
+
+| Entity | Events | Notes |
+|--------|--------|-------|
+| **Companies** | Create, Update | Real-time company changes |
+| **Tickets** | Create, Update | New tickets and status updates |
+| **Tasks** | Create, Update | Task creation and modifications |
+| **Projects** | Create, Update | Project changes |
+| **Time Entries** | Create, Update | New time entries |
+| **Contacts** | Create, Update | Contact information changes |
+| **Contracts** | Create, Update | Contract updates |
+| **Configuration Items** | Create, Update | Asset changes |
+
+**Note:** Delete events are supported but less common in Autotask workflows.
+
+---
+
+## Prerequisites
+
+Before setting up webhooks, ensure you have:
+
+1. **Autotask API Access**
+   - API user with appropriate permissions
+   - API integration enabled in Autotask
+
+2. **Public Webhook Endpoint**
+   - Your Pulse instance must be accessible from the internet
+   - HTTPS endpoint (required by Autotask)
+   - Example: `https://your-pulse-instance.com/api/webhooks/autotask`
+
+3. **Database Migration**
+   - Run migration `004_webhook_support.sql` to create webhook tables
+   ```bash
+   docker exec pulse-postgres psql -U pulse_user -d pulse_autotask -f /migrations/004_webhook_support.sql
+   ```
+
+---
+
+## Setup Steps
+
+### **Step 1: Configure Webhook Endpoint in Autotask**
+
+1. Log in to Autotask as an administrator
+2. Navigate to **Admin** → **Features & Settings** → **API & Integrations**
+3. Click on **Webhooks**
+4. Click **New Webhook**
+
+### **Step 2: Create Webhook for Each Entity**
+
+For each entity you want to track (e.g., Tickets):
+
+1. **Webhook Name:** `Pulse - Tickets`
+2. **Endpoint URL:** `https://your-pulse-instance.com/api/webhooks/autotask`
+3. **Entity Type:** Select the entity (e.g., `Tickets`)
+4. **Events:** Select events to track:
+   - ✅ Create
+   - ✅ Update
+   - ⬜ Delete (optional)
+5. **Include Entity Data:** ✅ **Enabled** (recommended)
+   - This includes full entity data in the webhook payload
+   - Reduces need for additional API calls
+6. **Active:** ✅ **Enabled**
+7. Click **Save**
+
+### **Step 3: Record Webhook IDs**
+
+After creating each webhook, Autotask will provide a Webhook ID. Record these for reference:
+
+```
+Companies: webhook_12345
+Tickets: webhook_12346
+Tasks: webhook_12347
+Projects: webhook_12348
+TimeEntries: webhook_12349
+Contacts: webhook_12350
+```
+
+### **Step 4: Verify Webhook Configuration**
+
+Check that webhooks are configured in the database:
+
+```sql
+SELECT entity_type, is_active, autotask_webhook_id
+FROM webhook_configs
+ORDER BY entity_type;
+```
+
+Update webhook IDs if needed:
+
+```sql
+UPDATE webhook_configs
+SET autotask_webhook_id = 'webhook_12345'
+WHERE entity_type = 'Companies';
+```
+
+---
+
+## Webhook Endpoint
+
+### **Endpoint Details**
+
+- **URL:** `https://your-domain.com/api/webhooks/autotask`
+- **Method:** `POST`
+- **Content-Type:** `application/json`
+- **Authentication:** None (Autotask doesn't support webhook authentication)
+  - Secure via IP whitelisting or network-level security
+
+### **Payload Structure**
+
+Autotask sends webhooks with this structure:
+
+```json
+{
+  "eventId": "evt_abc123",
+  "eventType": "create",
+  "entityType": "Tickets",
+  "entityId": 12345,
+  "eventTimestamp": "2026-01-24T10:00:00Z",
+  "entity": {
+    "id": 12345,
+    "title": "New Ticket",
+    "status": 1,
+    "companyID": 67890,
+    ...
+  }
+}
+```
+
+### **Response**
+
+The endpoint returns:
+
+```json
+{
+  "success": true,
+  "eventId": "evt_abc123",
+  "action": "created",
+  "processingTime": 45
+}
+```
+
+---
+
+## Testing Webhooks
+
+### **1. Health Check**
+
+Verify the webhook endpoint is accessible:
+
+```bash
+curl https://your-pulse-instance.com/api/webhooks/autotask
+```
+
+Expected response:
+```json
+{
+  "status": "active",
+  "endpoint": "/api/webhooks/autotask",
+  "message": "Autotask webhook receiver is ready"
+}
+```
+
+### **2. Test Webhook from Autotask**
+
+1. In Autotask, go to the webhook configuration
+2. Click **Test Webhook**
+3. Autotask will send a test event
+4. Check webhook logs in Pulse
+
+### **3. Create Test Entity**
+
+Create a test ticket or company in Autotask and verify:
+
+1. Webhook is received (check logs)
+2. Entity appears in database
+3. Processing time is reasonable (<1 second)
+
+### **4. View Webhook Logs**
+
+```bash
+# Via API
+curl https://your-pulse-instance.com/api/webhooks/logs?limit=10
+
+# Via Database
+docker exec pulse-postgres psql -U pulse_user -d pulse_autotask -c \
+  "SELECT event_id, entity_type, entity_id, status, processing_time_ms 
+   FROM webhook_logs 
+   ORDER BY received_at DESC 
+   LIMIT 10;"
+```
+
+---
+
+## Monitoring
+
+### **Webhook Statistics**
+
+View webhook statistics via API:
+
+```bash
+curl https://your-pulse-instance.com/api/webhooks/stats?hours=24
+```
+
+Response:
+```json
+{
+  "success": true,
+  "stats": {
+    "total": 150,
+    "processed": 148,
+    "failed": 2,
+    "pending": 0,
+    "byEntityType": {
+      "Tickets": 75,
+      "Companies": 25,
+      "Tasks": 30,
+      "TimeEntries": 20
+    }
+  },
+  "period": "24 hours"
+}
+```
+
+### **Failed Webhooks**
+
+Check for failed webhook processing:
+
+```sql
+SELECT event_id, entity_type, entity_id, error_message, received_at
+FROM webhook_logs
+WHERE status = 'failed'
+ORDER BY received_at DESC
+LIMIT 20;
+```
+
+### **Processing Performance**
+
+Monitor webhook processing times:
+
+```sql
+SELECT 
+  entity_type,
+  COUNT(*) as total,
+  AVG(processing_time_ms) as avg_ms,
+  MAX(processing_time_ms) as max_ms
+FROM webhook_logs
+WHERE status = 'processed'
+  AND received_at >= NOW() - INTERVAL '24 hours'
+GROUP BY entity_type
+ORDER BY avg_ms DESC;
+```
+
+---
+
+## Troubleshooting
+
+### **Webhooks Not Received**
+
+**Check 1: Endpoint Accessibility**
+```bash
+# From external network
+curl https://your-pulse-instance.com/api/webhooks/autotask
+```
+
+**Check 2: Firewall/Network**
+- Ensure port 443 (HTTPS) is open
+- Check firewall rules allow Autotask IPs
+- Verify SSL certificate is valid
+
+**Check 3: Autotask Configuration**
+- Verify webhook is Active in Autotask
+- Check endpoint URL is correct
+- Ensure entity type matches
+
+### **Webhooks Failing to Process**
+
+**Check Logs:**
+```sql
+SELECT event_id, entity_type, error_message, payload
+FROM webhook_logs
+WHERE status = 'failed'
+ORDER BY received_at DESC
+LIMIT 5;
+```
+
+**Common Issues:**
+
+1. **Missing Entity Data**
+   - Enable "Include Entity Data" in Autotask webhook config
+   - Without this, webhook only includes entity ID
+
+2. **Foreign Key Violations**
+   - Run full sync for dependent entities first
+   - Example: Sync Companies before Tickets
+
+3. **Invalid Data**
+   - Check entity mapper for missing field mappings
+   - Review error_message in webhook_logs
+
+### **High Failure Rate**
+
+If >5% of webhooks fail:
+
+1. **Run Full Sync** for affected entities
+2. **Check Dependencies** - ensure parent entities are synced
+3. **Review Error Patterns** - look for common error messages
+4. **Contact Support** - if issues persist
+
+---
+
+## Recommended Sync Strategy
+
+### **Optimal Configuration**
+
+Combine webhooks with scheduled syncs for best results:
+
+#### **1. Webhooks (Real-Time)**
+- **Enabled for:** Companies, Tickets, Tasks, Projects, Time Entries, Contacts
+- **Events:** Create, Update
+- **Purpose:** Instant updates for active entities
+
+#### **2. Daily Incremental Sync (Scheduled)**
+- **Time:** 2:00 AM daily
+- **Entities:** All entities
+- **Purpose:** 
+  - Catch any missed webhooks
+  - Sync entities without webhooks (Contracts, Config Items, Picklists)
+  - Ensure data consistency
+
+#### **3. Weekly Full Sync (Scheduled)**
+- **Time:** Sunday 3:00 AM
+- **Entities:** All entities
+- **Date Range:** Last 2 years
+- **Purpose:**
+  - Complete data refresh
+  - Verify data integrity
+  - Sync historical changes
+
+### **Cron Schedule Example**
+
+```bash
+# Daily incremental sync at 2 AM
+0 2 * * * curl -X POST https://your-pulse-instance.com/api/sync/incremental
+
+# Weekly full sync on Sunday at 3 AM
+0 3 * * 0 curl -X POST https://your-pulse-instance.com/api/sync/full
+```
+
+### **Expected Data Freshness**
+
+| Entity | Freshness | Method |
+|--------|-----------|--------|
+| Tickets | <1 minute | Webhook |
+| Tasks | <1 minute | Webhook |
+| Companies | <1 minute | Webhook |
+| Projects | <1 minute | Webhook |
+| Time Entries | <1 minute | Webhook |
+| Contacts | <1 minute | Webhook |
+| Contracts | 24 hours | Daily sync |
+| Config Items | 24 hours | Daily sync |
+| Picklists | 7 days | Weekly sync |
+
+---
+
+## Security Considerations
+
+### **1. Network Security**
+
+**Option A: IP Whitelisting**
+- Restrict webhook endpoint to Autotask IP ranges
+- Configure in firewall or reverse proxy
+
+**Option B: VPN/Private Network**
+- Use VPN tunnel for webhook traffic
+- More secure but complex setup
+
+### **2. Payload Validation**
+
+The webhook service validates:
+- Required fields (eventId, eventType, entityType, entityId)
+- Event ID uniqueness (prevents duplicate processing)
+- Entity type is supported
+
+### **3. Rate Limiting**
+
+Consider adding rate limiting to prevent abuse:
+```nginx
+# Nginx example
+limit_req_zone $binary_remote_addr zone=webhook:10m rate=100r/m;
+
+location /api/webhooks/autotask {
+    limit_req zone=webhook burst=20;
+    proxy_pass http://pulse-app:3100;
+}
+```
+
+---
+
+## Database Schema
+
+### **webhook_logs Table**
+
+Tracks all incoming webhook events:
+
+```sql
+CREATE TABLE webhook_logs (
+  id SERIAL PRIMARY KEY,
+  event_id VARCHAR(255) NOT NULL UNIQUE,
+  entity_type VARCHAR(100) NOT NULL,
+  entity_id INTEGER NOT NULL,
+  event_type VARCHAR(50) NOT NULL,
+  status VARCHAR(50) NOT NULL DEFAULT 'pending',
+  error_message TEXT,
+  received_at TIMESTAMP NOT NULL DEFAULT NOW(),
+  processed_at TIMESTAMP,
+  processing_time_ms INTEGER,
+  payload JSONB NOT NULL
+);
+```
+
+### **webhook_configs Table**
+
+Manages webhook configurations:
+
+```sql
+CREATE TABLE webhook_configs (
+  id SERIAL PRIMARY KEY,
+  entity_type VARCHAR(100) NOT NULL UNIQUE,
+  event_types JSONB NOT NULL,
+  is_active BOOLEAN NOT NULL DEFAULT true,
+  autotask_webhook_id VARCHAR(255)
+);
+```
+
+---
+
+## API Reference
+
+### **Receive Webhook**
+
+```
