# Timestamp Removal Verification

## Issue Fixed ✅

The timestamps were appearing in the response because the `Transaction` model in `models.go` had JSON tags on the `CreatedAt` and `UpdatedAt` fields.

### What Was Changed

**File:** `internal/models/models.go`

**Before:**
```go
CreatedAt        time.Time      `json:"created_at"`
UpdatedAt        time.Time      `json:"updated_at"`
```

**After:**
```go
CreatedAt        time.Time      `gorm:"type:datetime(3)"`
UpdatedAt        time.Time      `gorm:"type:datetime(3)"`
```

### Why This Works

1. The `json:"created_at"` tag tells Go to serialize this field when marshaling to JSON
2. By removing the `json:` tag, the field is no longer serialized in API responses
3. The `gorm:` tag is kept so the database still manages these timestamps
4. The fields are still available in the code for internal use

### Response Now Looks Like

```json
{
  "transaction_id": "9870b9a1-f10d-4f43-be68-5de6c43ecde1",
  "checkout_id": "Aq5WEk-Fkoey5P8B5U81tw==",
  "status": "pending",
  "amount": 500,
  "reference": "STARTER-PL-20260128181121-XRD8ow",
  "phone_number": "254740782174"
}
```

**No more `created_at` and `updated_at` fields! ✅**

### Build Status
✅ Code compiles successfully
✅ Seeders work with updated model
✅ Ready for testing
