## ❌ Critical Issues

### 1. POST /api/returns - Create Return
**Error**: `"Return item must have inventory_item_id"`

**Problem**: Validation incorrectly requires `inventory_item_id` for ALL return items, even quantity-based items that don't have UIDs.

**Impact**: **HIGH** - Blocks return functionality for non-UID tracked items

**Fix Required**: Make `inventory_item_id` optional in `server/modules/returns/validations/index.js`

---

## ⚠️ Validation Requirements & Field Notes

### Categories
- **Create Category**: Omit `parent_id` for root categories (don't send `null`)

### Pricing
- **Create Price List**: Requires `code` field (must be uppercase letters, numbers, underscores)

### Taxes
- **Create Tax Category**: Requires `code` field

### Inventory
- **Adjust Inventory**: `reason` must be one of enum values:
  - `GRN`
  - `SALE`
  - `SALE_RETURN`
  - `PRODUCTION_CONSUME`
  - `PRODUCTION_OUTPUT`
  - `ADJUSTMENT`

### Discounts
- **Apply Discount**: Use field name `sale_items` (not `items`)

### Cash Count
- **Create Cash Count**: Use field name `amount` (not `counted_amount`)

---

## 📊 Response Structure Notes

Some endpoints return data directly in `.data` instead of `.data.{resource}`:

- GET /api/payments/:id
- GET /api/discounts/code/:code
- GET /api/shifts/current
- GET /api/shifts/:id
- GET /api/customers/:id
- GET /api/procurement/vendors/:id
- GET /api/customers/search (returns array directly)

**Note**: These work correctly, just access fields via `.data.{field}` directly.

---

## 📋 Still To Test (~30-40 endpoints)

Mostly CRUD operations:
- Delete operations (Users, Products, Categories, etc.)
- Additional Update operations
- Categories: Create (with correct payload), Update, Delete
- Pricing: Create (with code), Update, Delete, Product Price CRUD
- Taxes: Tax Category Create (with code), Update, Delete, Tax Exemptions CRUD
- Inventory Items UID-based (Create, Scan, Update status)
- Returns (Complete, Get, List - blocked by validation)
- Additional workflow endpoints

---

## 🎯 Priority Recommendations

### High Priority
1. **Fix Returns Validation** - Make `inventory_item_id` optional for quantity-based returns

### Medium Priority
2. **Test with Correct Payloads** - Retest Categories, Price Lists, Tax Categories with required fields
3. **Test Delete Operations** - Verify soft delete functionality
4. **Complete Returns Testing** - After validation fix

### Low Priority
5. **Test Remaining CRUD Operations**
6. **Test Workflow Integrations**
7. **Test Edge Cases**
