+# Stripe Implementation - Verification Complete ✅
+
+## Implementation Review Summary
+
+The Stripe integration for Biblical Guide donations has been thoroughly reviewed and all issues have been fixed.
+
+## Issues Found & Fixed
+
+### 1. ✅ Stripe API Version
+**Issue:** Used incorrect API version `2025-01-27.acacia`
+**Fixed:** Updated to `2025-09-30.clover` (matches installed Stripe v19.1.0)
+**Location:** `lib/stripe.ts:10`
+
+### 2. ✅ PrismaClient Singleton
+**Issue:** API routes created new PrismaClient instances (causes connection issues)
+**Fixed:** Updated to use existing singleton from `lib/db.ts`
+**Locations:**
+- `app/api/stripe/checkout/route.ts`
+- `app/api/stripe/webhook/route.ts`
+
+### 3. ✅ Locale Parameter
+**Issue:** Success/cancel URLs didn't include locale parameter
+**Fixed:**
+- Added locale parameter to checkout API
+- Updated donate page to send locale
+- URLs now use `/${locale}/donate/success` format
+**Locations:**
+- `app/api/stripe/checkout/route.ts:31,51-52`
+- `app/[locale]/donate/page.tsx:37,104`
+
+### 4. ✅ MUI Grid v7 Compatibility
+**Issue:** Used deprecated Grid `item` and `container` props (MUI v7)
+**Fixed:** Replaced Grid with Box-based flexbox/CSS grid layout
+**Location:** `app/[locale]/donate/page.tsx`
+
+### 5. ✅ useSearchParams Suspense Boundary
+**Issue:** `useSearchParams()` in success page needed Suspense wrapper
+**Fixed:** Wrapped component in Suspense boundary with loading fallback
+**Location:** `app/[locale]/donate/success/page.tsx`
+

+
+3. **Test:**
+   - Visit `/en/donate`
+   - Use test card: `4242 4242 4242 4242`
+   - Verify webhook events in Stripe CLI
+   - Check database for donation records
+
+4. **Go Live:**
+   - Switch to live Stripe keys
