+# 🔐 LittleShop System Credentials & Configuration
+
+**Date Created:** September 25, 2025
+**Commit:** 127be75
+**Status:** Production Ready with Manual Payment Verification
+
+## 🎯 **System Architecture Overview**
+
+The LittleShop system has evolved into a **manual payment verification workflow** that is more reliable than automated webhooks for cryptocurrency transactions. The admin panel provides comprehensive tools for payment verification and order management.
+
+### **Key Discovery: Manual Payment Verification**
+- **Location:** Admin Panel → Orders → Order Details page (`/Admin/Orders/Details/{id}`)
+- **Function:** Displays crypto payment information and allows manual status updates
+- **Workflow:** Order Creation → Payment Address Generation → Manual Verification → Status Updates
+- **Advantage:** More reliable than webhook automation for crypto payments
+
+## 🔑 **Critical Credentials to Retain**
+
+### **SilverPAY Integration**
+```bash
+SILVERPAY_BASE_URL="http://31.97.57.205:8001"
+SILVERPAY_API_KEY="sk_live_edba50ac32dfa7f997b2597d5785afdbaf17b8a9f4a73dfbbd46dbe2a02e5757"
+SILVERPAY_WEBHOOK_SECRET="your-webhook-secret-here"
+SILVERPAY_WEBHOOK_URL="https://littleshop.silverlabs.uk/api/silverpay/webhook"
+```
+
+### **JWT Authentication**
+```bash
+JWT_SECRET_KEY="YourSuperSecretKeyHereThatIsAtLeast32CharactersLongForSecurity2025!"
+JWT_ISSUER="LittleShop-Production"
+JWT_AUDIENCE="LittleShop-Production"
+```
+
+### **WebPush Notifications (VAPID Keys)**
+```bash
+WEBPUSH_VAPID_PUBLIC_KEY="BMc6fFJZ8oIQKQzcl3kMnP9tTsjrm3oI_VxLt3lAGYUMWGInzDKn7jqclEoZzjvXy1QXGFb3dIun8mVBwh-QuS4"
+WEBPUSH_VAPID_PRIVATE_KEY="Gs9Sp4eqhsv0vNJkdgzoYmM7C3Db0xp9KdkRRnJEfOI"
+WEBPUSH_SUBJECT="mailto:admin@littleshop.com"
+```
+
+### **Hostinger VPS Access**
+```bash
+VPS_HOST="srv1002428.hstgr.cloud"
+VPS_USER="root"
+VPS_PORT="2255"
+# Password stored in ~/.claude/Knowledge/
+```
+
+### **Admin Panel Access**
+```bash
+Username: admin
+Password: admin
+URL: http://localhost:8080/Admin (development)
+URL: https://admin.thebankofdebbie.giize.com/Admin (production)
+```
+
+## 🏗️ **System Components**
+
+### **Core Applications**
+- **LittleShop API**: ASP.NET Core 9.0 Web API + MVC Admin Panel
+- **SilverPAY Gateway**: Cryptocurrency payment processing
+- **Database**: SQLite (development) / PostgreSQL (production)
+- **Authentication**: Dual-mode (Cookie for Admin + JWT for API)
+
+### **Manual Payment Verification Workflow**
+1. Customer creates order through TeleBot or API
+2. System generates SilverPAY payment address and crypto amount
+3. Admin monitors Order Details page for payment confirmation
+4. Admin manually updates order status from "Pending Payment" to "Payment Received"
+5. Order proceeds through fulfillment workflow
+
+### **Deployment Scripts**
+- **`deploy_to_hostinger.sh`**: Full VPS deployment automation
+- **`set_production_env.sh`**: Environment variable configuration
+- **`test-deployment-complete.sh`**: E2E testing suite
+- **`cleanup-test-data.sh`**: Test data cleanup utilities
+
+## 📁 **Critical Files and Locations**
+
+### **Manual Payment UI**
+- **File:** `LittleShop/Areas/Admin/Views/Orders/Details.cshtml` (lines 202-226)
+- **Function:** Displays crypto payment details with manual verification controls
+- **Fields:** Required Amount, Paid Amount, Wallet Address, Payment Status
+
+### **Test Data Cleanup**
+- **API Endpoint:** `POST /api/test/cleanup-test-data`
+- **Shell Script:** `cleanup-test-data.sh`
+- **Function:** Removes all orders with `IdentityReference` starting with "test-"
+
+### **Configuration Scripts**
+- **Environment Setup:** `set_production_env.sh`
+- **Systemd Service:** Configured in `deploy_to_hostinger.sh`
+- **Nginx Config:** `nginx_littleshop.conf`
+
+## 🚀 **Deployment Commands**
+
+### **Development Environment**
+```bash
+cd /mnt/c/Production/Source/LittleShop
+source set_production_env.sh
+cd LittleShop
+dotnet run --urls=http://localhost:8080
+```
+
+### **Production Deployment**
+```bash
+# Full automated deployment to Hostinger VPS
+bash deploy_to_hostinger.sh
+
+# Manual deployment steps
+dotnet publish -c Release -r linux-x64 --self-contained false
+scp -P 2255 publish/* root@srv1002428.hstgr.cloud:/opt/littleshop/
+ssh -p 2255 root@srv1002428.hstgr.cloud systemctl restart littleshop
+```
+
+### **Testing and Verification**
+```bash
+# Comprehensive E2E testing
+bash test-deployment-complete.sh
+
+# Local integration testing
+bash test_e2e_local.sh
+
+# Test data cleanup
+bash cleanup-test-data.sh
+```
+
+## 🔧 **System Maintenance**
+
+### **Test Data Cleanup**
+```bash
+# Remove all test orders and associated data
+curl -X POST http://localhost:8080/api/test/cleanup-test-data
+
+# Database direct cleanup (if needed)
+sqlite3 littleshop.db "DELETE FROM Orders WHERE IdentityReference LIKE 'test-%';"
+```
+
+### **Service Management**
+```bash
+# Check service status
+systemctl status littleshop
+
+# View logs
+journalctl -u littleshop -f
+
+# Restart service
+systemctl restart littleshop
+```
+
+### **Database Backup**
+```bash
+# Development (SQLite)
+cp littleshop-dev.db littleshop-dev.db.backup
+
+# Production (PostgreSQL)
+pg_dump littleshop > littleshop_backup_$(date +%Y%m%d).sql
+```
+
