# 🚨 DESKTOP CLIENT: EXACT PARAMETER FIX
## ❌ What You're Using (WRONG):
```json
{
"costType": "net_amortized_cost", // THIS PARAMETER DOESN'T EXIST!
"isUnblended": "true", // WRONG COMBINATION
"endDate": "2025-08-24",
"groupBy": "none",
"accountId": "932213950603",
"startDate": "2025-01-01",
"cloud_context": "aws",
"periodGranLevel": "month"
}
```
**Result**: Returns unblended costs ($104,755.07 for March)
## ✅ What You SHOULD Use (CORRECT):
### For Regular Amortized Costs:
```json
{
"accountId": "932213950603",
"startDate": "2025-01-01",
"endDate": "2025-08-24",
"groupBy": "none",
"periodGranLevel": "month",
"cloud_context": "aws",
"isAmortized": "true" // ✅ THIS IS THE CORRECT PARAMETER
}
```
**Expected Result**: March 2025 = $108,831.79
### For Net Amortized Costs (RI/SP Benefits):
```json
{
"accountId": "932213950603",
"startDate": "2025-01-01",
"endDate": "2025-08-24",
"groupBy": "none",
"periodGranLevel": "month",
"cloud_context": "aws",
"isNetAmortized": "true" // ✅ THIS IS THE CORRECT PARAMETER
}
```
**Expected Result**: March 2025 = $64,730.56
## 🔑 KEY CHANGES:
1. **REMOVE**: `costType` parameter - IT DOESN'T EXIST
2. **REMOVE**: `isUnblended` parameter - IT CAUSES CONFLICTS
3. **ADD**: `isAmortized: "true"` OR `isNetAmortized: "true"`
4. **KEEP**: All other parameters the same
## 🎯 WHY YOUR CURRENT APPROACH FAILS:
- `costType` parameter is **completely ignored** by the API
- `isUnblended: "true"` forces unblended costs regardless of other parameters
- You're getting the SAME data every time because wrong parameters default to unblended
## ✅ HOW TO VERIFY SUCCESS:
**Before (Your Current Results):**
- March 2025: $104,755.07 (unblended)
**After (Correct Parameters):**
- March 2025 Regular Amortized: $108,831.79
- March 2025 Net Amortized: $64,730.56
**Server Response Should Say:**
- "regular amortized costs" or "net amortized costs"
- NOT "returns unblended costs"
## 🚨 CRITICAL INSIGHT:
The API response note about "ask for 'net amortized costs'" means use `isNetAmortized: "true"` parameter - NOT invent a `costType` parameter!
