## ⚠️ Issues Found

### 1. Response Structure Issues

#### 1.1 Get Payment by ID
**Endpoint**: `GET /api/payments/:id`
**Issue**: Response may use `.data.id` instead of `.data.payment.id`
**Status**: Needs verification

#### 1.2 Get Discount by Code
**Endpoint**: `GET /api/discounts/code/:code`
**Issue**: Response may use `.data.id` instead of `.data.discount.id`
**Status**: Needs verification

#### 1.3 Get Current Shift
**Endpoint**: `GET /api/shifts/current`
**Issue**: Response may use `.data.id` instead of `.data.shift.id`
**Status**: Needs verification

#### 1.4 Low Stock Items Report
**Endpoint**: `GET /api/reports/inventory/low-stock`
**Issue**: Response structure may not use `.data.items` array
**Status**: Needs verification

---

### 2. Validation/Field Name Issues

#### 2.1 Cash Count
**Endpoint**: `POST /api/shifts/:id/cash-counts`
**Error**: "Cash count amount is required"
**Issue**: Field name mismatch - API expects `amount` but validation may expect `counted_amount`
**Payload Used**: `{"amount": 15000.00, "notes": "..."}`
**Status**: Needs field name verification

#### 2.2 Apply Discount
**Endpoint**: `POST /api/discounts/apply`
**Error**: May have field name mismatch
**Payload Used**: `{"discount_id": 1, "items": [...], "customer_id": 3}`
**Expected**: May need `sale_items` instead of `items`
**Status**: Needs verification

#### 2.3 Create Return
**Endpoint**: `POST /api/returns`
**Error**: "Return item must have inventory_item_id"
**Issue**: For quantity-based items (non-UID), `inventory_item_id` should be optional
**Payload Used**: `{"sale_id": 7, "items": [{"sale_item_id": 7, "quantity": 1}]}`
**Status**: Validation logic issue - quantity-based returns shouldn't require inventory_item_id

---

### 3. Report Endpoints Errors

#### 3.1 Sales Report by Date
**Endpoint**: `GET /api/reports/sales/by-date`
**Issue**: Returns error - needs investigation
**Status**: Needs debugging

## 📋 Priority Fixes Needed

### High Priority
1. **Create Return** - Fix validation to allow quantity-based returns without inventory_item_id
2. **Sales Report by Date** - Debug and fix error
3. **Shift Report** - Debug and fix error

### Medium Priority
4. **Response Structure Consistency** - Standardize response formats for:
   - Get Payment by ID
   - Get Discount by Code
   - Get Current Shift
   - Low Stock Items Report
5. **Field Name Verification** - Check correct field names for:
   - Cash Count (amount vs counted_amount)
   - Apply Discount (items vs sale_items)

### Low Priority
6. **Test Remaining Endpoints** - Complete testing of all untested APIs

## Notes

- Most core functionality is working correctly
- Main issues are response structure inconsistencies and validation logic
- Sale creation fix (transaction rollback & user association) is working perfectly
- Payment processing is working
- KRA eTIMS fiscalisation is working (with mock API)
