# Stephane's 500 Credits Purchase Issue - Root Cause & Fix

**Date:** 2025-12-19  
**User:** Stephane (Taz) - User ID: 5, Email: stevenberg450@gmail.com  
**Issue:** Purchased 500 credits (Premium package) for $129.00 but credits were not added to account

---

## What Happened

1. **Payment Intent Created:** `pi_3SbUdyD0zXLMB4gH1P4poDyJ` on 2025-12-06 23:12:02
2. **Payment Succeeded:** Status confirmed in Stripe on 2025-12-06 23:12:16
3. **Webhook Received:** `payment_intent.succeeded` event received
4. **Credits NOT Added:** Credits were not added to user's account

---

## Root Cause

The webhook handler (`webhooks/stripe.php`) in `processMixedCartPayment()` function was **not handling the minimal format** for credit items in cart metadata.

### The Problem

Stripe metadata used **minimal format** for cart items:
```json
{
  "t": "credit",    // type (minimal)
  "i": "premium",   // package/ID (minimal)
  "q": 1,           // quantity (minimal)
  "a": 12900        // amount (minimal)
}
```

But the code only checked for **full format**:
```php
if ($item['type'] === 'credit') {
    if (isset($item['credits']) && isset($item['package'])) {
        // Process credits
    }
}
```

This meant:
- ✅ Webhook was received
- ✅ Payment was confirmed
- ❌ Credits were NOT processed (missing `credits` and `package` fields in minimal format)
- ❌ Error was logged but credits were never added

---

## The Fix

### 1. Updated Webhook Handler (`webhooks/stripe.php`)

**Changed:** Credit processing now handles both full and minimal formats:

```php
// Handle both full format (type, credits, package) and minimal format (t, i, q, a)
$item_type = $item['type'] ?? $item['t'] ?? null;

if ($item_type === 'credit') {
    // Handle both formats
    $package = $item['package'] ?? $item['i'] ?? null;
    $credits = $item['credits'] ?? null;
    $quantity = $item['quantity'] ?? $item['q'] ?? 1;
    
    // If credits not provided, calculate from package
    if (!$credits && $package) {
        $package_credits_map = [
            'starter' => 30,
            'pro' => 150,
            'premium' => 500
        ];
        $credits = ($package_credits_map[$package] ?? 0) * $quantity;
    }
    
    if ($credits && $credits > 0 && $package) {
        addCreditsToUser($user_id, $credits, $package, $subscription_period, $paymentIntent->id);
    }
}
```

**Benefits:**
- ✅ Handles both full format (`type`, `credits`, `package`) and minimal format (`t`, `i`, `q`, `a`)
- ✅ Automatically calculates credits from package name if not provided
- ✅ Better error logging with detailed information

### 2. Created Diagnostic Script (`check_stephane_500_credits.php`)

**Purpose:** Verify payment in Stripe and fix database if needed

**Features:**
- ✅ Checks user's current credits in database
- ✅ Verifies payment intent in Stripe
- ✅ Checks webhook logs
- ✅ Checks action logs
- ✅ Checks credit purchase records
- ✅ **One-click fix button** to add missing credits (admin only)

**Usage:**
1. Visit: `https://soundstudiopro.com/check_stephane_500_credits.php`
2. Review all information
3. Click "🔧 Fix: Add 500 Credits" button (admin only)
4. Credits will be added immediately

---

## Verification Steps

### Check Payment in Stripe:
```bash
# Payment Intent ID: pi_3SbUdyD0zXLMB4gH1P4poDyJ
# Status: succeeded
# Amount: $129.00
# User ID: 5
# Package: premium
# Credits: 500
```

### Check Database:
```sql
SELECT * FROM credit_purchases WHERE payment_intent_id = 'pi_3SbUdyD0zXLMB4gH1P4poDyJ';
SELECT credits FROM users WHERE id = 5;
```

### Check Logs:
- `logs/stripe_webhooks.log` - Webhook received ✅
- `logs/stripe_actions.log` - Action processed (check for errors)
- `logs/mixed_cart_payments.log` - Cart processing
- `logs/user_credits.log` - Credit addition (should show success)

---

## Immediate Action Required

1. **Run Diagnostic Script:**
   - Visit: `https://soundstudiopro.com/check_stephane_500_credits.php`
   - Click "🔧 Fix: Add 500 Credits" button
   - Verify credits are added

2. **Verify Fix:**
   - Check user's credits in database
   - Confirm credit purchase record exists
   - Test that future purchases work correctly

---

## Prevention

The fix ensures that:
- ✅ **Future purchases** will work correctly (both formats supported)
- ✅ **Better error logging** helps identify issues faster
- ✅ **Automatic credit calculation** from package name prevents missing credits
