# Backend API Endpoints - Test Results

**Test Date:** December 5, 2025
**Backend URL:** http://localhost:8011

## ✅ WORKING ENDPOINTS

### Billing API Endpoints

| Endpoint | Method | Status | Notes |
|----------|--------|--------|-------|
| `/api/v1/billing/invoices/` | GET | ✅ 401 | Auth required (correct) |
| `/api/v1/billing/payments/` | GET | ✅ 401 | Auth required (correct) |
| `/api/v1/billing/credit-packages/` | GET | ✅ 401 | Auth required (correct) |
| `/api/v1/billing/transactions/` | GET | ✅ 401 | Auth required (correct) |
| `/api/v1/billing/transactions/balance/` | GET | ✅ 401 | Auth required (correct) |
| `/api/v1/billing/admin/stats/` | GET | ✅ 401 | Auth required (correct) |

### Account Endpoints

| Endpoint | Method | Status | Notes |
|----------|--------|--------|-------|
| `/api/v1/account/settings/` | GET | ✅ 401 | Auth required (correct) |
| `/api/v1/account/settings/` | PATCH | ✅ 401 | Auth required (correct) |
| `/api/v1/account/team/` | GET | ✅ 401 | Auth required (correct) |
| `/api/v1/account/usage/analytics/` | GET | ✅ 401 | Auth required (correct) |

## ❌ ISSUES FIXED

### Frontend API Path Alignment
**Problem:** Frontend must always call the canonical `/api/v1/billing/...` endpoints (no `/v2` alias).

**Files Fixed:**
- `frontend/src/services/billing.api.ts` – ensured all billing calls use `/v1/billing/...`

**Changes:**
```typescript
// Before:
fetchAPI('/billing/invoices/')

// After:
fetchAPI('/v1/billing/invoices/')
```

### Component Export Issues
**Problem:** `PricingPlan` type export conflict

**File Fixed:**
- `frontend/src/components/ui/pricing-table/index.tsx`

**Change:**
```typescript
// Before:
export { PricingPlan };

// After:
export type { PricingPlan };
```

### Missing Function Issues
**Problem:** `submitManualPayment` doesn't exist, should be `createManualPayment`

**File Fixed:**
- `frontend/src/pages/account/PurchaseCreditsPage.tsx`

**Change:**
```typescript
// Import changed:
import { submitManualPayment } from '...'  // ❌
import { createManualPayment } from '...'  // ✅

// Usage changed:
await submitManualPayment({...})  // ❌
await createManualPayment({...})  // ✅
```

## 🔧 URL STRUCTURE

### Correct URL Pattern
```
Frontend calls: /v1/billing/invoices/
                ↓
API Base URL:   https://api.igny8.com/api
                ↓
Full URL:       https://api.igny8.com/api/v1/billing/invoices/
                ↓
Backend route:  /api/v1/billing/ → igny8_core.business.billing.urls
```

### API Base URL Detection
```typescript
// frontend/src/services/api.ts
const API_BASE_URL = getApiBaseUrl();

// Returns:
// - localhost:3000 → http://localhost:8011/api
// - Production → https://api.igny8.com/api
```

## ✅ BUILD STATUS

```bash
cd /data/app/igny8/frontend
npm run build
# ✅ built in 10.87s
```
