# LQC (Lead → Quote → Contract) API Integration - Implementation Summary

**Date:** February 3, 2026  
**Status:** ✅ Complete  
**API Base URL:** `http://your-api-domain/api/crm`

---

## 📋 What Was Implemented

### Backend (Laravel - limozxAPI)

#### 1. **REST API Controllers** (4 Controllers)
- ✅ [CrmLeadController.php](app/Http/Controllers/Api/CrmLeadController.php) - Lead CRUD operations
- ✅ [CrmQuoteController.php](app/Http/Controllers/Api/CrmQuoteController.php) - Quote CRUD operations
- ✅ [CrmContractController.php](app/Http/Controllers/Api/CrmContractController.php) - Contract CRUD operations
- ✅ [CrmContactController.php](app/Http/Controllers/Api/CrmContactController.php) - Contact CRUD operations

#### 2. **API Routes** (Protected with JWT Auth)
Added to `routes/api.php`:
```
POST   /api/crm/leads          - Create lead
GET    /api/crm/leads          - List leads (with filtering)
GET    /api/crm/leads/{id}     - Get single lead
PUT    /api/crm/leads/{id}     - Update lead
DELETE /api/crm/leads/{id}     - Delete lead

POST   /api/crm/quotes         - Create quote
GET    /api/crm/quotes         - List quotes (with filtering)
GET    /api/crm/quotes/{id}    - Get single quote
PUT    /api/crm/quotes/{id}    - Update quote
DELETE /api/crm/quotes/{id}    - Delete quote

POST   /api/crm/contracts      - Create contract
GET    /api/crm/contracts      - List contracts (with filtering)

GET    /api/crm/contacts/{id}  - Get single contact
PUT    /api/crm/contacts/{id}  - Update contact
DELETE /api/crm/contacts/{id}  - Delete contact
```

#### 3. **Authorization Policies**
- ✅ [CrmLeadPolicy.php](app/Policies/CrmLeadPolicy.php) - Tenant isolation for leads
- ✅ [CrmQuotePolicy.php](app/Policies/CrmQuotePolicy.php) - Tenant isolation for quotes
- ✅ [CrmContractPolicy.php](app/Policies/CrmContractPolicy.php) - Tenant isolation for contracts
- ✅ [CrmContactPolicy.php](app/Policies/CrmContactPolicy.php) - Tenant isolation for contacts

#### 4. **Database Models & Migrations**
- ✅ Models already exist: `CrmLead`, `CrmQuote`, `CrmContract`, `CorporateClient`
- ✅ Migrations already created (2026_01_19_000030+)
- ✅ Relationships configured for data integrity

#### 5. **Data Seeding**

## 🚀 Quick Start Guide

### 1. **Set Up Backend**

```bash
# Copy to your limozxAPI folder
cd c:\Apps\Lima\limozxAPI

# Run migrations (if not already done)
php artisan migrate

# Run the CRM seeder to populate demo data
php artisan db:seed --class=CrmLeadSeeder

# Clear cache
php artisan cache:clear
php artisan config:clear
```

### 2. **Frontend Integration**

The Angular component at `http://localhost:4200/operator-admin/lqc` will:
- Automatically load leads from `/api/crm/leads`
- Display them in a table with filtering
- Allow adding new leads
- Support converting leads to quotes
- Handle errors gracefully with fallback demo data

### 3. **Test the API**

**Using cURL:**
```bash
# Get all leads (requires JWT token)
curl -X GET "http://localhost:8000/api/crm/leads" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Accept: application/json"

# Create a lead
curl -X POST "http://localhost:8000/api/crm/leads" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "lead_name": "Test Company",
    "lead_email": "test@company.com",
    "source_type": "website",
    "company_name": "Test Company Inc",
    "estimated_monthly_budget": 500000
  }'
```

## 🔐 Security Features

✅ **Tenant Isolation** - Users only see their own tenant's data  
✅ **Authorization Policies** - Database-level permission checks  
✅ **Form Validation** - Server-side validation on all inputs  
✅ **Input Sanitization** - Protection against injection attacks

## 🐛 Troubleshooting

### Issue: 401 Unauthorized
**Solution:** Make sure JWT token is valid and included in Authorization header

### Issue: 403 Forbidden
**Solution:** Check that your user has correct tenant_id assigned

### Issue: No data loading in Angular
**Solution:** 
1. Check browser console for errors
2. Verify API endpoint is correct
3. Check JWT token expiration
4. Component will fallback to demo data if API fails

### Issue: Data not persisting
**Solution:**
1. Verify database connection in .env
2. Check migrations have run: `php artisan migrate:status`
3. Review Laravel logs: `storage/logs/laravel.log`
