## ❌ Critical Issue to Fix

### 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 (most products)

**Location**: `server/modules/returns/validations/index.js`

**Fix Required**: Make `inventory_item_id` optional in return item validation. Only require it for UID-tracked items.

**Expected Behavior**:
- For quantity-based items: `inventory_item_id` should be optional/null
- For UID-tracked items: `inventory_item_id` should be required

## ⚠️ Clarifications (Not Errors)

### 1. Response Structure Variations
These APIs work correctly but return data directly in `.data` instead of `.data.{resource}`:

- **GET /api/payments/:id** - Returns `.data.{fields}` directly (not `.data.payment`)
- **GET /api/discounts/code/:code** - Returns `.data.{fields}` directly (not `.data.discount`)
- **GET /api/shifts/current** - Returns `.data.{fields}` directly (not `.data.shift`)

**Note**: These are working correctly, just use `.data` directly when accessing fields.

### 2. Route Path Corrections
- **Sales Report**: Use `/api/reports/sales/date` (NOT `/api/reports/sales/by-date`)
- **Shift Report**: Use `/api/reports/shifts?shift_id=:id` (NOT `/api/reports/shifts/:id`)

### 3. Field Name Notes
- **Apply Discount**: Use `"sale_items"` (not `"items"`)
- **Cash Count**: Use `"amount"` (not `"counted_amount"`)

### 4. Business Logic Notes
- **Apply Discount**: Requires discount rules to be created first. Error "Discount has no rules" is expected if discount has no rules configured.

## 🎯 Priority Recommendations

### High Priority (Fix Immediately)
1. **Fix Return Validation** - Make `inventory_item_id` optional for quantity-based returns
   - Location: `server/modules/returns/validations/index.js`
   - Impact: Blocks core return functionality

### Medium Priority (Documentation/Clarification)
1. **Update API Testing Guide** - Correct route paths for reports
2. **Document Response Structures** - Note variations in response formats
3. **Document Field Names** - Clarify correct field names (sale_items, amount, etc.)

### Low Priority (Complete Testing)
1. Test remaining CRUD operations
2. Test additional report endpoints
3. Test workflow integrations
