#### 5. Required Scopes

Based on ShopCall.ai functionality, we need:

```
product:read          # Read product catalog
product:write         # Update product information (if needed)
customer:read         # Access customer data (including email, phone, addresses)
customer:write        # Update customer information (notes, tags)
order:read            # Read order information (including customer email, phone)
order:write           # Update order status, add notes
category:read         # Read product categories
inventory:read        # Access real-time stock information
webhook:read          # List existing webhooks
webhook:write         # Create/update webhooks for real-time sync
```

**Scope Justification:**
- **product:read** - Sync product catalog for AI knowledge base
- **product:write** - Future capability to update stock levels, prices
- **customer:read** - Access customer data including email, phone numbers, billing/shipping addresses for personalized AI responses
- **customer:write** - Add call notes, tags, and interaction history to customer records
- **order:read** - Access order details including customer contact info (email, phone) for order status inquiries
- **order:write** - Update order notes and status after customer calls
- **category:read** - Organize products by category for better AI product recommendations
- **inventory:read** - Provide real-time stock availability information during calls
- **webhook:read** - List existing webhook registrations to avoid duplicates
- **webhook:write** - Register webhooks for real-time product/order/customer updates

## 🔐 OAuth Flow Implementation

### Installation Process Flow

```mermaid
sequenceDiagram
    participant Merchant
    participant ShopRenter
    participant ShopCall Backend
    participant Database

    Merchant->>ShopRenter: Click "Install ShopCall.ai"
    ShopRenter->>ShopCall Backend: GET /auth/shoprenter/callback?shopname=X&code=Y&timestamp=Z&hmac=H&app_url=U
    ShopCall Backend->>ShopCall Backend: Validate HMAC (sha256)
    alt HMAC Valid
        ShopCall Backend->>Database: Store installation data
        ShopCall Backend->>Merchant: Redirect to app_url
        ShopRenter->>ShopCall Backend: GET /integrations/shoprenter/entry?shopname=X&code=Y&timestamp=Z&hmac=H
        ShopCall Backend->>ShopCall Backend: Validate HMAC again
        ShopCall Backend->>ShopCall Backend: Request OAuth token from ShopRenter
        ShopCall Backend->>Database: Store access token
        ShopCall Backend->>Merchant: Show success page
    else HMAC Invalid
        ShopCall Backend->>Merchant: Show error (403)
    end
```

### HMAC Validation Process

**ShopRenter sends:**
```
GET /auth/shoprenter/callback?shopname=example&code=0907a61c0c8d55e99db179b68161bc00&timestamp=1337178173&hmac=d48e5d...&app_url=...
```

**Validation Algorithm:**

```javascript
function validateHMAC(query, clientSecret) {
  // 1. Extract HMAC from query
  const { hmac, ...params } = query;

  // 2. Build query string without HMAC (sorted alphabetically)
  const sortedParams = Object.keys(params)
    .sort()
    .map(key => `${key}=${params[key]}`)
    .join('&');

  // Example: "code=0907a61c0c8d55e99db179b68161bc00&shopname=example&timestamp=1337178173"

  // 3. Generate HMAC using sha256
  const crypto = require('crypto');
  const calculatedHmac = crypto
    .createHmac('sha256', clientSecret)
    .update(sortedParams)
    .digest('hex');

  // 4. Compare (timing-safe)
  return crypto.timingSafeEqual(
    Buffer.from(calculatedHmac),
    Buffer.from(hmac)
  );
}
```

**Security Notes:**
- ⚠️ **Always validate HMAC** before processing request
- ⚠️ Use timing-safe comparison to prevent timing attacks
- ⚠️ Check timestamp to prevent replay attacks (within 5 minutes)
- ⚠️ Store ClientSecret securely in environment variables

---

```

**Note:** All Edge Functions are deployed as serverless functions on Supabase infrastructure.

### 1. Environment Configuration

**Environment Variables (Supabase Edge Functions):**

```typescript
// Accessed via Deno.env.get() in Edge Functions
const config = {
  clientId: Deno.env.get('SHOPRENTER_CLIENT_ID'),
  clientSecret: Deno.env.get('SHOPRENTER_CLIENT_SECRET'),

  // Supabase URLs
  supabaseUrl: Deno.env.get('SUPABASE_URL'),
  supabaseAnonKey: Deno.env.get('SUPABASE_ANON_KEY'),
  supabaseServiceKey: Deno.env.get('SUPABASE_SERVICE_ROLE_KEY'),

  // Frontend URL
  frontendUrl: Deno.env.get('FRONTEND_URL'),

  // Production endpoints
  redirectUri: 'https://ztklqodcdjeqpsvhlpud.supabase.co/functions/v1/oauth-shoprenter-callback',
  entryPoint: 'https://shopcall.ai/integrations',
  uninstallUri: 'https://ztklqodcdjeqpsvhlpud.supabase.co/functions/v1/webhook-shoprenter-uninstall',

  // Required scopes
  scopes: [
    'product:read',
    'customer:read',
    'order:read',
    'order:write',
    'webhook:write'
  ],

  // Rate limiting
  maxRequestsPerSecond: 5,
  tokenExpiryBuffer: 300, // Refresh 5 min before expiry
};
```

**Configuration in supabase/.env:**
```bash
SHOPRENTER_CLIENT_ID=your_client_id_here
SHOPRENTER_CLIENT_SECRET=your_client_secret_here
SUPABASE_URL=https://ztklqodcdjeqpsvhlpud.supabase.co
SUPABASE_ANON_KEY=your_anon_key
SUPABASE_SERVICE_ROLE_KEY=your_service_role_key
FRONTEND_URL=https://shopcall.ai
INTERNAL_SYNC_SECRET=your_random_secure_secret
```

### 2. HMAC Validator (`_shared/shoprenter-client.ts`)

**Note:** HMAC validation is implemented in the shared ShopRenter client library used by all Edge Functions.

```typescript
import { createHmac, timingSafeEqual } from "https://deno.land/std@0.177.0/node/crypto.ts";

/**
 * Validate HMAC signature from ShopRenter
 * @param query - Query parameters from request
 * @param clientSecret - ShopRenter client secret
 * @returns True if HMAC is valid
 */
function validateHMAC(query: Record<string, string>, clientSecret: string): boolean {
  const { hmac, ...params } = query;

  if (!hmac) {
    console.error('[ShopRenter] HMAC missing from request');
    return false;
  }

  // Build sorted query string without HMAC
  const sortedParams = Object.keys(params)
    .sort()
    .map(key => `${key}=${params[key]}`)
    .join('&');

  // Calculate HMAC using sha256
  const calculatedHmac = createHmac('sha256', clientSecret)
    .update(sortedParams)
    .digest('hex');

  // Timing-safe comparison
  try {
    return timingSafeEqual(
      new TextEncoder().encode(calculatedHmac),
      new TextEncoder().encode(hmac)
    );
  } catch (error) {
    console.error('[ShopRenter] HMAC comparison error:', error);
    return false;
  }
}

/**
 * Validate request timestamp (prevent replay attacks)
 * @param timestamp - Unix timestamp from request
 * @param maxAgeSeconds - Maximum age allowed (default: 300 = 5 min)
 * @returns True if timestamp is within valid range
 */
function validateTimestamp(timestamp: string, maxAgeSeconds = 300): boolean {
  const requestTime = parseInt(timestamp, 10);
  const currentTime = Math.floor(Date.now() / 1000);
  const age = currentTime - requestTime;

  if (age < 0) {
    console.error('[ShopRenter] Request timestamp is in the future');
    return false;
  }

  if (age > maxAgeSeconds) {
    console.error(`[ShopRenter] Request timestamp too old: ${age}s > ${maxAgeSeconds}s`);
    return false;
  }

  return true;
}

/**
 * Validate complete ShopRenter request
 * @param query - Query parameters
 * @param clientSecret - ShopRenter client secret
 * @returns Validation result
 */
function validateRequest(
  query: Record<string, string>,
  clientSecret: string
): { valid: boolean; error?: string } {
  // Check required parameters
  const required = ['shopname', 'code', 'timestamp', 'hmac'];
  const missing = required.filter(param => !query[param]);

  if (missing.length > 0) {
    return {
      valid: false,
      error: `Missing required parameters: ${missing.join(', ')}`
    };
  }

  // Validate timestamp
  if (!validateTimestamp(query.timestamp)) {
    return {
      valid: false,
      error: 'Request timestamp invalid or expired'
    };
  }

  // Validate HMAC
  if (!validateHMAC(query, clientSecret)) {
    return {
      valid: false,
      error: 'HMAC validation failed'
    };
  }

  return { valid: true };
}

export {
  validateHMAC,
  validateTimestamp,
  validateRequest
};
```

### 3. OAuth Handler (Edge Functions)

**Implementation:** The OAuth flow is handled by two Edge Functions:
- `oauth-shoprenter-init` - Initiates OAuth flow
- `oauth-shoprenter-callback` - Handles OAuth callback and token exchange

**Example TypeScript Code (simplified from actual implementation):**

```typescript
import { createClient } from 'https://esm.sh/@supabase/supabase-js@2';

const supabase = createClient(
  Deno.env.get('SUPABASE_URL')!,
  Deno.env.get('SUPABASE_SERVICE_ROLE_KEY')!
);

/**
 * Exchange authorization code for access token
 * @param shopname - Store name
 * @param code - Authorization code
 * @returns Token response
 */
async function exchangeCodeForToken(shopname: string, code: string) {
  const tokenUrl = `https://${shopname}.shoprenter.hu/oauth/token`;
  const clientId = Deno.env.get('SHOPRENTER_CLIENT_ID')!;
  const clientSecret = Deno.env.get('SHOPRENTER_CLIENT_SECRET')!;
  const redirectUri = 'https://ztklqodcdjeqpsvhlpud.supabase.co/functions/v1/oauth-shoprenter-callback';

  try {
    const response = await fetch(tokenUrl, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        'Accept': 'application/json'
      },
      body: JSON.stringify({
        grant_type: 'authorization_code',
        client_id: clientId,
        client_secret: clientSecret,
        code: code,
        redirect_uri: redirectUri
      })
    });

    if (!response.ok) {
      throw new Error(`Token exchange failed: ${response.statusText}`);
    }

    const data = await response.json();
    console.log(`[ShopRenter] Token acquired for ${shopname}`);
    return data;
  } catch (error) {
    console.error('[ShopRenter] Token exchange error:', error);
    throw new Error('Failed to exchange code for token');
  }
}

/**
 * Store ShopRenter credentials in database
 * Note: Actual implementation in oauth-shoprenter-callback Edge Function
 */
async function storeCredentials(userId: string, shopname: string, tokenData: any) {
  const shopDomain = `${shopname}.shoprenter.hu`;
  const expiresAt = new Date(Date.now() + (tokenData.expires_in * 1000));

  // 1. Create or update stores record
  const { data: store, error: storeError } = await supabase
    .from('stores')
    .upsert({
      user_id: userId,
      platform_name: 'shoprenter',
      store_name: shopname,

      api_key: tokenData.access_token,
      api_secret: tokenData.refresh_token,
      token_expires_at: expiresAt.toISOString(),
      scopes: tokenData.scope ? tokenData.scope.split(' ') : [],
      is_active: true,
      connected_at: new Date().toISOString()
    })
    .select()
    .single();

  if (storeError) {
    console.error('[ShopRenter] Error storing store:', storeError);
    throw storeError;
  }

  console.log(`[ShopRenter] Credentials stored for ${shopname}`);
  return store;
}

// Additional functions for token refresh are implemented in the ShopRenter client library
// See: supabase/functions/_shared/shoprenter-client.ts
```

```typescript
import { ShopRenterConnect } from './ShopRenterConnect';

// In the platforms grid, add:
<div className="grid gap-6 md:grid-cols-3">
  {/* Existing Shopify card */}
  {/* Existing WooCommerce card */}

  {/* New ShopRenter card */}
  <ShopRenterConnect />
</div>
```

## 🔒 Security Considerations

### 1. HMAC Validation
- ✅ **Always validate HMAC** on every request from ShopRenter
- ✅ Use timing-safe comparison (`crypto.timingSafeEqual`)
- ✅ Validate timestamp to prevent replay attacks (5-minute window)

### 2. Token Storage
- ✅ Store access tokens encrypted in database
- ✅ Never log or expose tokens in responses
- ✅ Implement automatic token refresh
- ✅ Revoke tokens on uninstall

### 3. API Communication
- ✅ Always use HTTPS for all endpoints
- ✅ Implement rate limiting (5 req/sec per ShopRenter guidelines)
- ✅ Handle API errors gracefully
- ✅ Implement retry logic with exponential backoff

### 4. Data Privacy (GDPR Compliance)
- ✅ Only request necessary scopes
- ✅ Implement data deletion on uninstall
- ✅ Provide clear privacy policy
- ✅ Handle customer data securely

### 5. Environment Variables

```bash
# .env for backend
SHOPRENTER_APP_ID=your_app_id_here
SHOPRENTER_CLIENT_ID=your_client_id_here
SHOPRENTER_CLIENT_SECRET=your_client_secret_here
```

**⚠️ Never commit these to version control!**

---

## 🧪 Testing Strategy

### 1. Test Store Setup

1. Request test store at: https://www.shoprenter.hu/tesztigenyles/?devstore=1
2. Store name: `shopcall-test-store`
3. URL: `shopcall-test-store.myshoprenter.hu`

### 2. Test Cases

#### OAuth Flow Testing

```
Test Case 1: Successful Installation
- Initiate OAuth from ShopRenter admin
- Verify HMAC validation passes
- Verify token exchange succeeds
- Verify credentials stored in database
- Verify redirect to success page

Test Case 2: Invalid HMAC
- Modify HMAC parameter
- Verify request rejected with 403
- Verify error logged

Test Case 3: Expired Timestamp
- Use timestamp older than 5 minutes
- Verify request rejected
- Verify error logged

Test Case 4: Uninstall Flow
- Trigger uninstall from ShopRenter
- Verify webhook received
- Verify store deactivated
- Verify tokens deactivated
```

#### API Testing

```
Test Case 5: Product Sync
- Request product list from API
- Verify products cached in database
- Verify product data accuracy

Test Case 6: Token Refresh
- Wait for token expiry
- Make API request
- Verify token auto-refreshed
- Verify new token stored

Test Case 7: Webhook Processing
- Create test order in ShopRenter
- Verify webhook received
- Verify order data processed
- Verify response 200 sent
```

### 3. Integration Testing Tools

```javascript
// test/shoprenter-integration.test.js
const axios = require('axios');
const crypto = require('crypto');

describe('ShopRenter Integration', () => {
  const testShop = 'shopcall-test-store';
  const clientSecret = process.env.SHOPRENTER_CLIENT_SECRET;

  function generateValidHMAC(params) {
    const sorted = Object.keys(params)
      .sort()
      .map(key => `${key}=${params[key]}`)
      .join('&');

    return crypto
      .createHmac('sha256', clientSecret)
      .update(sorted)
      .digest('hex');
  }

  it('should validate correct HMAC', async () => {
    const params = {
      shopname: testShop,
      code: 'test123',
      timestamp: Math.floor(Date.now() / 1000).toString()
    };

    params.hmac = generateValidHMAC(params);

    const response = await axios.get('http://localhost:3000/auth/shoprenter/callback', {
      params,
      maxRedirects: 0,
      validateStatus: () => true
    });

    expect(response.status).not.toBe(403);
  });

  it('should reject invalid HMAC', async () => {
    const params = {
      shopname: testShop,
      code: 'test123',
      timestamp: Math.floor(Date.now() / 1000).toString(),
      hmac: 'invalid_hmac'
    };

    const response = await axios.get('http://localhost:3000/auth/shoprenter/callback', {
      params,
      maxRedirects: 0,
      validateStatus: () => true
    });

    expect(response.status).toBe(403);
  });
});
```

## 📌 Scheduled Background Sync

### Implementation Details

The ShopRenter integration includes automated background synchronization using PostgreSQL's `pg_cron` extension.

**How it Works:**
1. **pg_cron** schedules database jobs at hourly intervals
2. **Database trigger function** (`trigger_shoprenter_scheduled_sync()`) makes HTTP request to Edge Function
3. **`shoprenter-scheduled-sync` Edge Function** processes all active ShopRenter stores
4. **Sync results** are logged to `sync_logs` table

**Configuration:**
- Runs hourly at minute 0 (`:00`)
- Configurable per store via `store_sync_config` table
- Sync frequencies: `15min`, `30min`, `hourly`, `6hours`, `daily`
- Can be enabled/disabled per store
- Choose what to sync: products, orders, customers

**Monitoring:**
```sql
-- View recent sync logs
SELECT * FROM sync_logs
WHERE platform = 'shoprenter'
ORDER BY created_at DESC
LIMIT 10;

-- Check store sync configuration
SELECT * FROM store_sync_config
WHERE store_id IN (
  SELECT id FROM stores WHERE platform_name = 'shoprenter'
);
```

**Manual Control:**
```sql
-- Enable/disable sync for a store
SELECT set_store_sync_enabled('store-uuid', true);

-- Change sync frequency
SELECT set_store_sync_frequency('store-uuid', 'hourly');
```

**Database Configuration Required:**
```
-- In Supabase Dashboard → Project Settings → Database → Custom Postgres Configuration
app.internal_sync_secret = 'same_as_INTERNAL_SYNC_SECRET_in_env'
app.supabase_url = 'https://ztklqodcdjeqpsvhlpud.supabase.co'
```
