+# Quick Strapi Webhook Setup
+
+## TL;DR - Quick Configuration
+
+1. **Access Strapi Admin**: `http://localhost:1337/admin`
+2. **Go to Settings → Webhooks**
+3. **Add New Webhook**:
+   - **Name**: `Backend Sync`
+   - **URL**: `http://localhost:3000/api/v1/webhooks/strapi`
+   - **Events**: Select all for "Article" and "Live Blog" content types
+4. **Save and Test**
+
+## Already Configured (What We Fixed)
+
+✅ **Backend webhook endpoints** are now public (no auth required)  
+✅ **Tested webhooks** manually - they work  
+✅ **Articles sync** from Strapi to backend  
+✅ **Frontend TypeScript errors** fixed  
+✅ **Authentication system** working  
+
+## Manual Test Commands
+
+```bash
+# Test webhook manually
+curl -X POST http://localhost:3000/api/v1/webhooks/strapi \
+  -H "Content-Type: application/json" \
+  -d '{
+    "event": "entry.publish",
+    "model": "article",
+    "entry": {"documentId": "r07qatlpgvx82d7337n3nz1l"}
+  }'
+
+# Check synced articles
+curl http://localhost:3000/api/v1/articles?status=published
+
+# Run comprehensive test
+./scripts/test-webhooks.sh
+```
+
+## Current Status
+
+- **Strapi Articles**: 2
+- **Backend Articles**: 2 (synced)
+- **Webhook Status**: Ready for configuration
+- **Frontend**: Access at `http://localhost:5173/articles`
+
+## Immediate Action Required
+
+1. **Configure webhooks in Strapi admin** (see detailed guide in `STRAPI_WEBHOOKS_SETUP.md`)
+2. **Test by publishing an article** in Strapi
+3. **Verify automatic sync** works
+
+## If Webhooks Don't Work
+
+Use manual sync as fallback:
+```bash
+# Get auth token first
+TOKEN=$(curl -s -X POST http://localhost:3000/api/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"username":"testuser","password":"Test123!"}' | jq -r '.access_token')
+
+# Sync all articles
+curl -X POST http://localhost:3000/api/v1/webhooks/strapi/sync/all \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+## Verification
+- Visit `http://localhost:5173/articles` to see synced articles
+- Check backend logs: `docker logs placebo-backend-dev --tail 20`
+- Monitor sync status with test script: `./scripts/test-webhooks.sh`

+# Strapi Webhooks Configuration Guide
+
+## Overview
+This guide explains how to configure Strapi webhooks for automatic synchronization with the backend API. When articles or live blogs are published/updated/deleted in Strapi, webhooks will automatically trigger synchronization with the backend.
+
+## Webhook Endpoints
+
+The backend provides three webhook endpoints:
+
+1. **Article-specific webhook**: `POST /api/v1/webhooks/strapi/article`
+2. **Live Blog-specific webhook**: `POST /api/v1/webhooks/strapi/live-blog`
+3. **Generic webhook**: `POST /api/v1/webhooks/strapi` (handles both)
+
+All endpoints accept the following JSON format:
+```json
+{
+  "event": "entry.publish",  // or "entry.update", "entry.delete", "entry.unpublish"
+  "model": "article",        // or "live-blog"
+  "entry": {
+    "documentId": "unique-strapi-id"
+  }
+}
+```
+
+## Configuration Steps
+
+### Step 1: Access Strapi Admin Panel
+1. Open your browser and go to: `http://localhost:1337/admin`
+2. Log in with your admin credentials
+
+### Step 2: Configure Webhooks
+1. In the left sidebar, click on **Settings** (gear icon)
+2. Click on **Webhooks** under the "GLOBAL SETTINGS" section
+3. Click the **"Add new webhook"** button
+
+### Step 3: Configure Article Webhook
+**Basic Settings:**
+- **Name**: `Backend Article Sync`
+- **URL**: `http://localhost:3000/api/v1/webhooks/strapi/article`
+  - For Docker internal communication: `http://backend:3000/api/v1/webhooks/strapi/article`
+- **Headers**: Add if needed (usually not required)
+
+**Trigger Events:**
+Select the following events for the "Article" content type:
+- [x] **Create entry** (`entry.create`)
+- [x] **Update entry** (`entry.update`)
+- [x] **Delete entry** (`entry.delete`)
+- [x] **Publish entry** (`entry.publish`)
+- [x] **Unpublish entry** (`entry.unpublish`)
+
+**Save the webhook.**
+
+### Step 4: Configure Live Blog Webhook (Optional)
+Repeat Step 3 for live blogs:
+- **Name**: `Backend Live Blog Sync`
+- **URL**: `http://localhost:3000/api/v1/webhooks/strapi/live-blog`
+- Select events for the "Live Blog" content type
+
+### Alternative: Single Generic Webhook
+You can use a single webhook for all content types:
+- **Name**: `Backend Generic Sync`
+- **URL**: `http://localhost:3000/api/v1/webhooks/strapi`
+- Select events for ALL relevant content types (Article, Live Blog)
+
+## Testing Webhooks
+
+### Manual Test
+You can manually trigger a webhook to test the configuration:
+
+```bash
+# Test article webhook
+curl -X POST http://localhost:3000/api/v1/webhooks/strapi/article \
+  -H "Content-Type: application/json" \
+  -d '{
+    "event": "entry.publish",
+    "model": "article",
+    "entry": {
+      "documentId": "your-article-id"
+    }
+  }'
+
+# Test generic webhook
+curl -X POST http://localhost:3000/api/v1/webhooks/strapi \
+  -H "Content-Type: application/json" \
+  -d '{
+    "event": "entry.publish",
+    "model": "article",
+    "entry": {
+      "documentId": "your-article-id"
+    }
+  }'
+```
+
+### Test from Strapi
+1. In Strapi admin, edit any article
+2. Click "Save" or "Publish"
+3. Check backend logs for webhook receipt:
+   ```bash
+   docker logs placebo-backend-dev --tail 20 | grep -i "webhook\|strapi"
+   ```
+
+## Manual Sync (Fallback)
+If webhooks fail or for initial sync, use manual sync endpoints:
+
+```bash
+# Get authentication token first
+curl -X POST http://localhost:3000/api/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"username":"your-username","password":"your-password"}'
+
+# Sync all articles (requires auth)
+curl -X POST http://localhost:3000/api/v1/webhooks/strapi/sync/all \
+  -H "Authorization: Bearer YOUR_TOKEN_HERE"
+
+# Sync all live blogs
+curl -X POST http://localhost:3000/api/v1/webhooks/strapi/sync/live-blogs \
+  -H "Authorization: Bearer YOUR_TOKEN_HERE"
+
+# Sync everything
+curl -X POST http://localhost:3000/api/v1/webhooks/strapi/sync/everything \
+  -H "Authorization: Bearer YOUR_TOKEN_HERE"
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **Webhook not received by backend**
+   - Check backend logs: `docker logs placebo-backend-dev --tail 50`
+   - Verify CORS is configured (should allow `http://localhost:1337`)
+   - Test webhook manually with curl
+
+2. **401 Unauthorized error**
+   - Webhook endpoints are now public (no auth required)
+   - If getting 401, check that `@Public()` decorator is on webhook methods
+
+3. **Webhook received but sync fails**
+   - Check Strapi API token in backend `.env.docker`
+   - Verify Strapi is accessible from backend container
+   - Check backend logs for specific error messages
+
+4. **Article not appearing in frontend**
+   - Verify article is synced to backend: `curl http://localhost:3000/api/v1/articles`
+   - Check frontend browser console for errors
+   - Hard refresh frontend (Ctrl+F5)
+
+### Log Monitoring
+```bash
+# Monitor backend logs for webhooks
+docker logs -f placebo-backend-dev | grep -i "webhook\|strapi"
+
+# Monitor Strapi logs
+docker logs -f placebo-cms-dev
+
+# Check if articles are in backend
+curl -s "http://localhost:3000/api/v1/articles?status=published" | jq '.total'
+```
+
+## Docker Network Considerations
+
+### Internal Docker Communication
+- Within Docker network: Use `http://backend:3000` and `http://cms:1337`
+- From host machine: Use `http://localhost:3000` and `http://localhost:1337`
+
+### Webhook URL Examples
+- **From Strapi container to Backend**: `http://backend:3000/api/v1/webhooks/strapi`
+- **From Host to Backend**: `http://localhost:3000/api/v1/webhooks/strapi`
+- **External/Production**: Use your domain: `https://api.yourdomain.com/api/v1/webhooks/strapi`
+
+## Security Considerations
+
+1. **Webhook endpoints are public** - ensure your backend is not exposed to the public internet in production
+2. **Consider adding webhook signature verification** for production
+3. **Use HTTPS in production** for all webhook calls
+4. **Monitor webhook logs** for suspicious activity
+
+## Verification Checklist
+
+- [ ] Webhooks configured in Strapi admin
+- [ ] Test webhook manually works
+- [ ] Article publish in Strapi triggers sync
+- [ ] Synced articles appear in backend API
+- [ ] Frontend displays synced articles
+- [ ] All event types tested (publish, update, delete)
+
+## Support
+If issues persist:
+1. Check all service logs
+2. Verify network connectivity between containers
+3. Test each component independently
+4. Review error messages in logs
