✅ Asset Listing: /v6/folders/{folder_id}/children
✅ Asset Download: /v6/assets/{asset_id}/contents
✅ OAuth2 Token: /otdsws/oauth2/token
```

## 📊 VERIFIED WORKING DATA

### **Test Campaign: "LOCAL CAMPAIGN"**
- **Campaign ID:** C000000212
- **Brand:** KINDER SOFTY/BUENO EGGS
- **Market:** DE (Germany)
- **Asset ID:** 19c93aab68ff53f63f69d734604764e3b0f60dba

### **Folder Structure:**
```
LOCAL CAMPAIGN
├── 00. Master Assets (8469af29cb6119b3f09c97b8d8fc317497df6d43) - Empty
└── 01. Final Assets (841f8573c2691626f2102e5ec3253aa4bbed25c2) - 2 JPEG files
```

### **Downloaded Assets:**
- ✅ **2 JPEG image files** successfully downloaded
- ✅ **Proper file sizes** (not 211-byte error messages)
- ✅ **Organized storage** in downloads directory
- ✅ **Complete metadata** available for each asset

## 🐍 PYTHON MIGRATION PREPARATION

### **Ready for Implementation:**
All API patterns documented and tested. Python script can be built using:

**Command Structure:**
```bash
python3 download-script.py --campaign C000000212
python3 download-script.py --list-campaigns --stage "3 - Production & execution"  
python3 download-script.py --download-folder --campaign C000000212 --folder-type master
```

**API Integration:**
- **Authentication:** OAuth2 client credentials flow documented
- **Endpoints:** All URLs and parameters verified
- **Response parsing:** Data structures mapped
- **Error handling:** Common issues identified and solutions documented

### **Required for Optimal Python Workflow:**
**Properly structured campaigns** with:
- Source assets in **"00. Master Assets"** folder
- Empty **"01. Final Assets"** folder for processed outputs
- Multiple asset types for comprehensive processing

## 🎯 CURRENT STATUS: PRODUCTION READY

### **What Works Now:**
1. **Complete workflow** from campaign selection to asset download
2. **Reliable authentication** with automatic token management
3. **Asset discovery** and metadata extraction
4. **File downloads** with proper organization
5. **Error handling** and user guidance

### **What's Ready for Python:**
1. **API patterns documented** and tested
2. **Authentication flow** verified
3. **Data structures** mapped
4. **Download process** established

### **What's Needed for Optimal Workflow:**
1. **Client to provide properly structured campaign** with Master Assets
2. **Python script implementation** using documented patterns
3. **Asset processing workflow** integration
4. **Upload functionality** for processed files

## 🚀 ACCESS & USAGE

### **Main Interface:**
`http://localhost:8888/ferrero-opentext/clean_workflow.php`

### **Current Working Process:**
1. Load campaigns → Select "LOCAL CAMPAIGN" 
2. Get folders → Explore folder with assets
3. Download files → View metadata
4. Process locally → (Ready for upload functionality)
