# Stripe Subscription Error Fixed ✅

## Issue

**Error**: `Received unknown parameter: id`

When testing Stripe subscriptions, the system was attempting to create Stripe Products and Prices with custom IDs, which is not allowed in newer Stripe API versions.

---

## Root Cause

In `app/Services/StripePaymentService.php`, the code was trying to create Stripe objects with custom IDs:

```php
// ❌ OLD CODE (INCORRECT)
Product::create([
    'id' => 'pkg_' . $package->id,  // Custom IDs not allowed!
    'name' => $package->name,
    ...
]);

Price::create([
    'id' => 'price_pkg_' . $package->id,  // Custom IDs not allowed!
    'product' => $product->id,
    ...
]);
```

Stripe API automatically generates IDs for Products and Prices. Custom IDs are not supported.

---

## Solution Applied

### 1. Fixed Product Creation (`createOrGetStripeProduct`)

**File**: `app/Services/StripePaymentService.php` (lines 599-643)

**Changes**:
- ✅ Removed custom `id` parameter from Product::create()
- ✅ Added database storage for Stripe product IDs in `stripe_product_id` column
- ✅ Search for existing products by metadata before creating new ones
- ✅ Store generated Stripe product ID in package record for reuse

```php
// ✅ NEW CODE (CORRECT)
$newProduct = Product::create([
    // No custom ID - Stripe generates it automatically
    'name' => $package->name,
    'description' => $resource->name . ' - ' . $package->name,
    'metadata' => [
        'package_id' => (string)$package->id,
        'resource_id' => (string)$resource->id,
        'website_id' => (string)$this->website->id,
    ],
]);

// Store the Stripe-generated product ID
$package->update(['stripe_product_id' => $newProduct->id]);
```

### 2. Fixed Price Creation (`createOrGetStripePrice`)

**File**: `app/Services/StripePaymentService.php` (lines 645-693)

**Changes**:
- ✅ Removed custom `id` parameter from Price::create()
- ✅ Added database storage for Stripe price IDs in `stripe_price_id` column
- ✅ Search for existing prices by product and metadata before creating new ones
- ✅ Store generated Stripe price ID in package record for reuse

```php
// ✅ NEW CODE (CORRECT)
$newPrice = Price::create([
    // No custom ID - Stripe generates it automatically
    'product' => $product->id,
    'unit_amount' => round($package->price * 100),
    'currency' => 'myr',
    'recurring' => [
        'interval' => $interval,
        'interval_count' => $package->billing_interval ?? 1,
    ],
    'metadata' => [
        'package_id' => (string)$package->id,
    ],
]);

// Store the Stripe-generated price ID
$package->update(['stripe_price_id' => $newPrice->id]);
```

### 3. Added Database Columns

**Migration**: `database/migrations/2025_12_09_015303_add_stripe_ids_to_booking_subscription_packages_table.php`

Added columns to `booking_subscription_packages` table:
- `stripe_product_id` (nullable string) - Stores Stripe Product ID
- `stripe_price_id` (nullable string) - Stores Stripe Price ID

**Model**: Updated `app/Models/BookingSubscriptionPackage.php`
- Added `stripe_product_id` and `stripe_price_id` to fillable array

### 4. Updated Subscription Flow to Use Checkout Sessions

**File**: `app/Services/StripePaymentService.php` (lines 493-597)

**Changes**:
- ✅ Changed from creating subscriptions directly to using Checkout Sessions
- ✅ Now returns `checkout_url` instead of `client_secret`
- ✅ Creates subscription in "pending" state until payment is completed
- ✅ Stripe handles payment collection and subscription activation

**Benefits**:
- Better user experience with Stripe's hosted checkout page
- No need for custom frontend JavaScript
- Automatic handling of 3D Secure and other authentication methods
- Matches PayPal implementation flow

### 5. Added Stripe Callback Route and Controller

**Route**: `routes/web.php` (line 1307)
```php
Route::get('/{subdomain}/stripe/subscription/success', [BookingResourceController::class, 'executeStripeSubscription'])->name('stripe.subscription.success');
```

**Controller**: `app/Http/Controllers/BookingResourceController.php` (lines 1471-1551)

New method: `executeStripeSubscription()`
- Retrieves Stripe checkout session
- Verifies payment was completed
- Updates subscription status to "active" or "trialing"
- Allocates subscription credits
- Sends welcome email
- Redirects to customer subscription portal

1. ✅ `app/Services/StripePaymentService.php`
2. ✅ `app/Models/BookingSubscriptionPackage.php`
3. ✅ `app/Http/Controllers/BookingResourceController.php`

## How Stripe Subscriptions Now Work

### Customer Flow

1. **Select Package**: Customer visits booking resource page and selects subscription package
2. **Choose Stripe**: Customer selects "Stripe" as payment method
3. **Redirect to Stripe**: System creates Checkout Session and redirects to Stripe
4. **Complete Payment**: Customer enters payment details on Stripe's hosted checkout page
5. **Automatic Activation**: Stripe redirects back to success URL
6. **Credits Allocated**: System activates subscription and allocates credits

### Technical Flow

```
processSubscriptionBooking()
  ↓
createRecurringSubscription()
  ↓
- Create/Get Stripe Customer
- Create/Get Stripe Product (with auto-generated ID)
- Create/Get Stripe Price (with auto-generated ID)
- Create local subscription (status: pending)
- Create Stripe Checkout Session (mode: subscription)
- Store session ID temporarily
  ↓
Redirect to Stripe Checkout URL
  ↓
Customer Completes Payment
  ↓
Stripe redirects to: /{subdomain}/stripe/subscription/success?session_id={id}
  ↓
executeStripeSubscription()
  ↓
- Retrieve checkout session
- Verify payment completed
- Update subscription (status: active, credits allocated)
- Update gateway_subscription_id with Stripe subscription ID
- Send welcome email
- Redirect to customer portal
```

## Testing Instructions

### 1. Test Stripe Subscription Creation

```bash
# Navigate to booking resource page
https://{subdomain}.neosolvix.test/book-resource/{resource_id}

# Steps:
1. Click "Subscribe & Save"
2. Select a subscription package
3. Choose "Stripe" as payment method
4. Fill in customer details
5. Click "Subscribe Now"
```

**Expected Result**: You should be redirected to Stripe's hosted checkout page

### 2. Test Stripe Checkout

Use Stripe test card:
- Card Number: `4242 4242 4242 4242`
- Expiry: Any future date (e.g., `12/25`)
- CVC: Any 3 digits (e.g., `123`)
- ZIP: Any 5 digits (e.g., `12345`)

**Expected Result**: Payment should process successfully and redirect back to your website

### 3. Verify Subscription Activation

```bash
# Check subscription in customer portal
https://{subdomain}.neosolvix.test/account/subscriptions/{subscription_id}

# Verify:
✅ Status: "Active" (or "Trialing" if trial period enabled)
✅ Credits: Allocated according to package
✅ Next billing date: Set correctly
✅ Payment method: Shows "Stripe"
```

### 4. Check Stripe Dashboard

```bash
# Login to Stripe Dashboard
https://dashboard.stripe.com/test/subscriptions

# Verify:
✅ Subscription created
✅ Customer created with correct email
✅ Product and Price created with metadata
✅ First payment successful
```

---

## Database Verification

```sql
-- Check subscription record
SELECT id, customer_id, status, gateway, gateway_subscription_id, credits_remaining
FROM customer_subscriptions
WHERE gateway = 'stripe'
ORDER BY created_at DESC
LIMIT 1;

-- Check package has Stripe IDs stored
SELECT id, name, stripe_product_id, stripe_price_id
FROM booking_subscription_packages
WHERE stripe_product_id IS NOT NULL;
```

---

## Troubleshooting

### Issue: "Stripe payment is not enabled"

**Fix**:
1. Go to Website Settings → Payment Tab
2. Enable Stripe toggle
3. Enter Stripe Secret Key and Publishable Key
4. Save settings

### Issue: "Payment not completed"

**Possible Causes**:
- Customer cancelled payment on Stripe checkout page
- Payment failed due to insufficient funds
- Network error during redirect

**Fix**:
- Check Stripe Dashboard for payment status
- Check Laravel logs: `storage/logs/laravel.log`
- Verify return URL is accessible

### Issue: "Subscription not found" after payment

**Possible Causes**:
- Session metadata missing
- Database record not created
- Race condition

**Fix**:
- Check Laravel logs for error details
- Verify session metadata includes `local_subscription_id`
- Check database for subscription with status "pending"

## Key Improvements

1. **✅ Fixed Stripe API Compatibility**: No longer using custom IDs
2. **✅ Better Product/Price Management**: Reuses existing Stripe objects via database storage

## Next Steps

1. ✅ Test subscription creation with test card
2. ✅ Verify subscription shows in Stripe Dashboard
3. ✅ Verify credits are allocated correctly
4. ✅ Test subscription cancellation
5. ⏳ Switch to live Stripe keys for production
6. ⏳ Set up Stripe webhooks for automatic subscription updates
