+# Stripe Integration Implementation Summary
+
+## Overview
+
+Complete Stripe integration for Xtablo with a single "Standard" subscription plan.
+Uses custom Node.js API (Hono) with Supabase database for data storage.
+
+## ✅ What Has Been Implemented
+
+### 1. Database Schema (`sql/35_stripe_wrappers.sql`)
+
+#### Foreign Tables (Direct Stripe API Access)
+- `stripe.customers` - Query Stripe customers
+- `stripe.subscriptions` - Query Stripe subscriptions  
+- `stripe.products` - Query Stripe products
+- `stripe.prices` - Query Stripe prices
+
+#### Local Tables (Synced via Webhooks)
+- `public.stripe_customers` - Customer records with user mapping
+- `public.stripe_subscriptions` - Subscription history
+- `public.stripe_products` - Product catalog
+- `public.stripe_prices` - Pricing information
+
+#### Profile Enhancements
+- `profiles.is_paying` - Boolean flag for quick checks
+- `profiles.subscription_tier` - Current tier ('free' or 'standard')
+
+#### Helper Functions
+```sql
+-- Check if user is paying
+SELECT is_paying_user(auth.uid());
+
+-- Get subscription details
+SELECT * FROM get_user_subscription_status(auth.uid());
+
+-- Get Stripe customer ID
+SELECT get_user_stripe_customer_id(auth.uid());
+```
+
+#### Views
+- `active_subscriptions` - All active subs with user info
+
+#### Automatic Updates
+- Triggers automatically update `profiles.is_paying` when subscriptions change
+- `updated_at` timestamps managed automatically
+
+### 2. Webhook Handlers (`sql/36_stripe_webhooks.sql`)
+
+Includes functions to process all major Stripe events:
+
+**Customer Events:**
+- `handle_stripe_customer_created()`
+- `handle_stripe_customer_updated()`
+- `handle_stripe_customer_deleted()`
+
+**Product Events:**
+- `handle_stripe_product_upsert()`
+- `handle_stripe_product_deleted()`

+**Price Events:**
+- `handle_stripe_price_upsert()`
+- `handle_stripe_price_deleted()`
+
+**Subscription Events:**
+- `handle_stripe_subscription_upsert()`
+- `handle_stripe_subscription_deleted()`
+
+### 3. Backend API (`api/src/stripe.ts` & `api/src/stripe-webhook.ts`)
+
+**Endpoints:**
+- `POST /api/v1/stripe/webhook` - Stripe webhook handler
+- `POST /api/v1/stripe/create-checkout-session` - Start subscription checkout
+- `POST /api/v1/stripe/create-portal-session` - Open customer portal
+- `GET /api/v1/stripe/subscription` - Get user's subscription
+- `GET /api/v1/stripe/is-paying` - Check payment status
+- `GET /api/v1/stripe/prices` - Get Standard plan prices
+- `POST /api/v1/stripe/cancel-subscription` - Cancel at period end
+- `POST /api/v1/stripe/reactivate-subscription` - Reactivate subscription
+
+**Features:**
+- ✅ Automatic customer creation
+- ✅ Secure webhook signature verification
+- ✅ Complete subscription lifecycle management
+- ✅ Customer portal access
+- ✅ Subscription cancellation/reactivation
+
+### 4. Frontend Hooks (`apps/main/src/hooks/stripe.ts`)

+- `useStripePrices()` - Get available prices
+- `useCreateCheckoutSession()` - Start checkout
+- `useCreatePortalSession()` - Open portal
+- `useCancelSubscription()` - Cancel subscription
+- `useReactivateSubscription()` - Reactivate subscription
+
+### 5. TypeScript Types (`packages/shared/src/types/stripe.types.ts`)
+
+Complete type definitions:
+- `StripeCustomer`
+- `StripeSubscription`
+- `StripeProduct`
+- `StripePrice`
+- Helper functions for formatting and status checks
+
+### 6. Documentation (`docs/STRIPE_SETUP.md`)
+

+## 🎯 Key Features
+
+### Security
+- ✅ Row Level Security (RLS) on all tables
+- ✅ Users can only see their own data
+- ✅ Stripe API key stored securely in Vault
+- ✅ Webhook signature verification
+- ✅ Service role functions for webhooks
+
+### Performance
+- ✅ Indexed on user_id, customer_id, status
+- ✅ Efficient queries for subscription checks
+- ✅ Cached subscription status in profiles table
+
+### Data Integrity
+- ✅ Foreign key relationships
+- ✅ Cascading deletes
+- ✅ Automatic timestamp management
+- ✅ Transaction safety in webhook handlers
+
+## 📊 How to Check if User is Paying
+
+### Method 1: From Profile (Fastest)
+```typescript
+const user = useUser();
+if (user.is_paying) {
+  // User has active Standard subscription
+  console.log(`User is on ${user.subscription_tier} plan`); // 'standard'
+}
+```
+
+### Method 2: Using Function (Most Accurate)
+```typescript
+const { data: isPaying } = useQuery({
+  queryKey: ['is_paying', userId],
+  queryFn: async () => {
+    const { data } = await supabase.rpc('is_paying_user', {
+      user_uuid: userId
+    });
+    return data;
+  }
+});
+```
+
+### Method 3: Direct Query
+```typescript
+const { data: subscription } = await supabase
+  .from('stripe_subscriptions')
+  .select('*')
+  .eq('user_id', userId)
+  .in('status', ['active', 'trialing'])
+  .single();
+
+const isPaying = !!subscription;
+```
+
+## 🔄 Data Flow
+
+1. **User Clicks "Subscribe to Standard"**
+   → Frontend calls `/api/v1/stripe/create-checkout-session`
+   
+2. **API Creates Checkout**
+   → Creates/retrieves Stripe customer
+   → Creates checkout session
+   → Returns checkout URL
+
+3. **User Completes Payment**
+   → Stripe processes payment
+   → Fires `customer.subscription.created` webhook
+
+4. **Webhook Received**
+   → API endpoint `/api/v1/stripe/webhook` receives event
+   → Verifies signature
+   → Calls `handle_stripe_subscription_upsert()`
+
+5. **Database Updated**
+   → Inserts into `stripe_subscriptions`
+   → Trigger updates `profiles.is_paying = true` and `subscription_tier = 'standard'`
+
+6. **Frontend Updates**
+   → User's profile automatically shows paying status
+   → `user.is_paying = true`
+   → `user.subscription_tier = 'standard'`
+
+## 🚀 Next Steps to Complete Implementation
+
+### Required Setup:
+
+1. **Update Vault Key ID** 
+   - Get key_id after storing Stripe API key
+   - Update in `sql/35_stripe_wrappers.sql` line 27
+
+2. **Install Stripe SDK**
+   ```bash
+   cd api
+   npm install stripe @stripe/stripe-js

+   ```
+
+4. **Configure Frontend Environment**
+   Add to `apps/main/.env`:
+   ```env
+   VITE_STRIPE_PUBLISHABLE_KEY=pk_test_xxxxx
+   ```
+
+5. **Create "Standard" Plan in Stripe**
+   - Create product named exactly **"Standard"**
+   - Add pricing (monthly/yearly)
+   - Note price IDs for frontend
+
+6. **Configure Webhook in Stripe Dashboard**
+   - Add endpoint: `https://your-api.com/api/v1/stripe/webhook`

+
+---
+
+## 🎯 Single "Standard" Plan Architecture
+
+This implementation is optimized for a single subscription tier:
+
+**Plan Structure:**
+- **Free** - Default tier, `is_paying = false`
+- **Standard** - Paid tier, `is_paying = true`, `subscription_tier = 'standard'`
+
+**Why This Works:**
+- Simple pricing model
+- Easy to check: just `user.is_paying`
+- Future-proof: can add more tiers later by updating the tier logic
+- Webhook automatically handles upgrades/downgrades
+
+**API Endpoints Specific to Standard:**
+- `GET /api/v1/stripe/prices` - Returns only "Standard" plan prices
+- Creates customers with metadata linking to user_id
+- All subscriptions automatically set tier to 'standard'
+
+---
+
+**Implementation Status**: ✅ Complete (Database, API, Frontend, Types)  
+**Next Step**: Configure Stripe and test webhook integration

+```
+
+## 💡 Common Use Cases
+
+### Check if User is Paying
+```typescript
+const user = useUser();
+if (user.is_paying) {
+  // Show premium feature
+}
+```
+
+### Subscribe to Standard Plan
+```typescript
+const { mutate: checkout } = useCreateCheckoutSession();
+
+<button onClick={() => checkout({ priceId: 'price_xxxxx' })}>
+  Subscribe to Standard
+</button>
+```

+
+## ⚡ Quick Setup
+
+### 1. Install Dependencies
+```bash
+cd api && npm install stripe @stripe/stripe-js
+cd ../apps/main && npm install @stripe/stripe-js
+```
+
+### 2. Run Database Migrations
+Execute in Supabase SQL Editor:
+```sql
+\i sql/35_stripe_wrappers.sql
+\i sql/36_stripe_webhooks.sql
+```
+
+### 3. Configure Stripe Dashboard
+1. Create product named **"Standard"**
+2. Add monthly/yearly pricing
+3. Save the price IDs
+4. Add webhook endpoint: `https://your-api.com/api/v1/stripe/webhook`
+5. Copy webhook signing secret
+
+### 4. Set Environment Variables
+
+**API (`.env`):**
+```env
+STRIPE_SECRET_KEY=sk_test_xxxxx
+STRIPE_WEBHOOK_SECRET=whsec_xxxxx
+SUPABASE_SERVICE_ROLE_KEY=your_key
+FRONTEND_URL=http://localhost:5173
+```
+
+**Frontend (`apps/main/.env`):**
+```env
+VITE_STRIPE_PUBLISHABLE_KEY=pk_test_xxxxx
+VITE_STRIPE_STANDARD_MONTHLY_PRICE_ID=price_xxxxx
+```
+
+### 5. Add Subscription Card to Settings
+
+In `apps/main/src/pages/settings.tsx`:
+
+```typescript
+import { SubscriptionCard } from "../components/SubscriptionCard";
+
+// Inside your settings page JSX, add:
+<SubscriptionCard />
+```
+
+## 🎯 How It Works
+
+### User Journey
+
+1. **Free User** sees upgrade prompt in SubscriptionCard
+2. Clicks "Passer à Standard"
+3. Redirected to Stripe Checkout
+4. Completes payment
+5. Redirected back to settings with `?success=true`
+6. Webhook updates database
+7. `user.is_paying` becomes `true`
+8. `user.subscription_tier` becomes `'standard'`
+9. UI automatically updates
+
+### Data Sync
+
+```
+Stripe → Webhook → API → Database → Frontend
+                           ↓
+                    profiles.is_paying = true
+```
+
+## 🎨 Using Subscription Card
+
+The `SubscriptionCard` component shows:
+
+**For Free Users:**
+- "Plan Gratuit" badge
+- "Passer à Standard" button
+- Initiates Stripe Checkout
+
+**For Paying Users:**
+- "Actif" badge
+- Current subscription details
+- Renewal date
+- "Gérer l'abonnement" button (opens Stripe portal)
+- "Annuler" button
+
+**For Canceling Users:**
+- "Annulation en cours" warning
+- Access until period end
+- "Réactiver l'abonnement" button
+
+## 🔍 Check Payment Status Anywhere
+
+```typescript
+import { useUser } from '../providers/UserStoreProvider';
+
+function PremiumFeature() {
+  const user = useUser();
+  
+  if (!user.is_paying) {
+    return <UpgradePrompt />;
+  }
+  
+  return <PremiumContent />;
+}
+```
+
+## 🎣 Available Hooks
+
+```typescript
+// Get subscription details
+const { data: subscription } = useSubscription();
+
+// Check if paying (boolean)
+const { data: isPaying } = useIsPayingUser();
+
+// Get available prices
+const { data: prices } = useStripePrices();
+
+// Create checkout session
+const { mutate: checkout } = useCreateCheckoutSession();
+checkout({ priceId: 'price_xxxxx' });
+
+// Open customer portal
+const { mutate: portal } = useCreatePortalSession();
+portal();
+
+// Cancel subscription
+const { mutate: cancel } = useCancelSubscription();
+cancel();
+
+// Reactivate subscription
+const { mutate: reactivate } = useReactivateSubscription();
+reactivate();
+```
+
+## 🧪 Testing
+
+### Test Cards
+```
+Success: 4242 4242 4242 4242
+Decline: 4000 0000 0000 0002

+
+## Prerequisites
+
+- Supabase project with database access
+- Stripe account (test mode for development)
+- Supabase Wrappers extension enabled
+- Node.js API already running
+
+## Database Setup
+
+### 1. Enable Wrappers Extension
+
+In your Supabase SQL Editor, enable the Wrappers extension:
+
+```sql
+create extension if not exists wrappers with schema extensions;
+```
+
+### 2. Store Stripe API Key in Vault
+
+```sql
+select vault.create_secret(
+  'sk_test_xxxxx',  -- Your Stripe secret key (test or live)
+  'stripe',
+  'Stripe API key for Wrappers'
+);
+```
+
+**Note the `key_id` returned** - you'll need this for the next step.
+
+### 3. Run Migration Scripts
+
+Execute the SQL migration files in order:
+
+```bash
+# From your Supabase SQL Editor
+1. Run: sql/35_stripe_wrappers.sql
+2. Run: sql/36_stripe_webhooks.sql
+```
+
+### 4. Update API Key ID
+
+In `35_stripe_wrappers.sql`, update line 27 with your actual `key_id` from step 2:
+
+```sql
+create server stripe_server
+  foreign data wrapper stripe_wrapper
+  options (
+    api_key_id 'YOUR_KEY_ID_HERE', -- Update this!
+    api_url 'https://api.stripe.com/v1/',
+    api_version '2024-06-20'
+  );
+```
+
+## Stripe Configuration
+
+### 1. Create Products and Prices
+
+In your Stripe Dashboard:
+
+1. Go to **Products**
+2. Click **Add product**
+3. Create your subscription tiers (e.g., "Premium", "Pro")
+4. Add pricing (monthly, yearly, etc.)
+5. Note the `price_id` (starts with `price_xxx`)
+
+### 2. Create the "Standard" Plan
+
+In your Stripe Dashboard:
+
+1. Go to **Products**
+2. Click **Add product**
+3. Name: **"Standard"** (important: must match exactly)
+4. Add your pricing:
+   - Monthly: e.g., €9.99/month
+   - Yearly: e.g., €99/year (optional)
+5. **Save the price IDs** (e.g., `price_xxxxx`)
+
+### 3. Set up Webhooks
+
+1. Go to **Developers → Webhooks** in Stripe Dashboard
+2. Click **Add endpoint**
+3. URL: `https://YOUR_API_URL/api/v1/stripe/webhook`
+4. Select events to listen to:
+   - `customer.created`
+   - `customer.updated`
+   - `customer.deleted`
+   - `customer.subscription.created`
+   - `customer.subscription.updated`
+   - `customer.subscription.deleted`
+   - `product.created`
+   - `product.updated`
+   - `product.deleted`
+   - `price.created`
+   - `price.updated`
+   - `price.deleted`
+5. **Copy the webhook signing secret** (starts with `whsec_`)
+
+## Backend API Setup
+
+The backend API handlers are already implemented in:
+
+- `api/src/stripe.ts` - Main Stripe routes
+- `api/src/stripe-webhook.ts` - Webhook handler
+- `api/src/routers.ts` - Router configuration
+
+### 1. Install Stripe SDK
+
+```bash
+cd api
+npm install stripe @stripe/stripe-js
+```
+
+### 2. Configure Environment Variables
+
+Add to your `.env` file:
+
+```env
+# Stripe
+STRIPE_SECRET_KEY=sk_test_xxxxx
+STRIPE_WEBHOOK_SECRET=whsec_xxxxx
+
+# For webhooks to work
+SUPABASE_SERVICE_ROLE_KEY=your_service_role_key
+```
+
+### 3. Restart API Server
+
+The Stripe routes are automatically registered at:
+
+- `POST /api/v1/stripe/webhook` - Webhook endpoint
+- `POST /api/v1/stripe/create-checkout-session` - Create checkout
+- `POST /api/v1/stripe/create-portal-session` - Customer portal
+- `GET /api/v1/stripe/subscription` - Get subscription status
+- `GET /api/v1/stripe/is-paying` - Check if paying
+- `GET /api/v1/stripe/prices` - Get available prices
+- `POST /api/v1/stripe/cancel-subscription` - Cancel subscription
+- `POST /api/v1/stripe/reactivate-subscription` - Reactivate subscription
+
+## Frontend Integration
+
+The frontend hooks are already implemented in `apps/main/src/hooks/stripe.ts`.
+
+### 1. Install Stripe SDK
+
+```bash
+cd apps/main
+npm install @stripe/stripe-js
+```
+
+### 2. Configure Environment Variable
+
+Add to `apps/main/.env`:
+
+```env
+VITE_STRIPE_PUBLISHABLE_KEY=pk_test_xxxxx
+```
+
+### 3. Available Hooks
+
+All hooks are ready to use:
+
+```typescript
+import {
+  useSubscription, // Get subscription details
+  useIsPayingUser, // Check if user is paying
+  useStripePrices, // Get available prices
+  useCreateCheckoutSession, // Start checkout flow
+  useCreatePortalSession, // Open customer portal
+  useCancelSubscription, // Cancel subscription
+  useReactivateSubscription, // Reactivate canceled subscription
+} from "../hooks/stripe";
+```
+
+## Usage Examples
+
+### Check if User is Paying
+
+```typescript
+// In any component
+const { data: isPaying } = useIsPayingUser();
+
+if (!isPaying) {
+  return <UpgradePrompt />;
+}
+```
+
+### Get Subscription Details
+
+```typescript
+const { data: subscription } = useSubscription();
+
+if (subscription) {
+  console.log("Status:", subscription.status);
+  console.log("Plan:", subscription.product_name);
+  console.log("Renews:", subscription.current_period_end);
+}
+```
+
+### Access Subscription Status from Profile
+
+```typescript
+// The user profile already has is_paying and subscription_tier fields
+const user = useUser();
+
+if (user.is_paying) {
+  console.log("User is on:", user.subscription_tier);
+}
+```
+
+### Create Checkout Session
+
+```typescript
+import { useCreateCheckoutSession } from "../hooks/stripe";
+
+function UpgradeButton() {
+  const { mutate: createCheckout, isPending } = useCreateCheckoutSession();
+
+  return (
+    <button
+      onClick={() =>
+        createCheckout({
+          priceId: "price_xxxxx", // Your Standard plan price ID
+        })
+      }
+      disabled={isPending}
+    >
+      {isPending ? "Loading..." : "Subscribe to Standard"}
+    </button>
+  );
+}
+```
+
+### Manage Subscription (Customer Portal)
+
+```typescript
+import { useCreatePortalSession } from "../hooks/stripe";
+
+function ManageSubscriptionButton() {
+  const { mutate: openPortal, isPending } = useCreatePortalSession();
+
+  return (
+    <button
+      onClick={() => openPortal(window.location.href)}
+      disabled={isPending}
+    >
+      Manage Subscription
+    </button>
+  );
+}
+```
+
+### Cancel Subscription
+
+```typescript
+import { useCancelSubscription } from "../hooks/stripe";
+
+function CancelButton() {
+  const { mutate: cancel, isPending } = useCancelSubscription();
+
+  return (
+    <button onClick={() => cancel()} disabled={isPending}>
+      Cancel Subscription
+    </button>
+  );
+}
+```
+
+## Testing
+
+### 1. Use Stripe Test Mode
+
+Use test cards from [Stripe Testing](https://stripe.com/docs/testing):
+
+- Success: `4242 4242 4242 4242`
+- Decline: `4000 0000 0000 0002`
+
+### 2. Test Webhooks Locally
+
+```bash
+# Install Stripe CLI
+brew install stripe/stripe-cli/stripe
+
+# Login
+stripe login
+
+# Forward webhooks to local API
+stripe listen --forward-to http://localhost:3000/api/v1/stripe/webhook
+```
+
+### 3. Trigger Test Events
+
+```bash
+stripe trigger customer.subscription.created
+stripe trigger customer.subscription.updated
+stripe trigger customer.subscription.deleted
+```
+
+## Security Checklist
+
+- [ ] Stripe API keys stored in Supabase Vault
+- [ ] Webhook signing secret configured
+- [ ] Row Level Security (RLS) enabled on all tables
+- [ ] Edge Function uses service role key
+- [ ] Customer metadata includes user_id for mapping
+- [ ] Test mode used for development
+
+## Troubleshooting
+
+### Webhooks Not Working
+
+1. Check webhook endpoint URL is correct (`https://your-api/api/v1/stripe/webhook`)
+2. Verify signing secret matches in `.env`
+3. Check API logs for webhook errors
+4. Ensure `SUPABASE_SERVICE_ROLE_KEY` is set in API environment
+5. Test with Stripe CLI: `stripe trigger customer.subscription.created`
+
+### Subscription Not Showing
+
+1. Verify customer has `user_id` in metadata
+2. Check webhook was received (Stripe Dashboard → Webhooks)
+3. Query `stripe_subscriptions` table directly
+4. Check `profiles.is_paying` was updated by trigger
+
+### Foreign Tables Empty
+
+1. Verify Stripe API key is correct
+2. Check key_id in server configuration
+3. Test with: `SELECT * FROM stripe.customers LIMIT 5;`
+4. Ensure Wrappers extension is enabled
+
+## Next Steps
+
+1. Create pricing page component
+2. Build subscription management UI
+3. Implement usage-based billing (if needed)
+4. Add customer portal for self-service
+5. Set up email notifications for billing events
