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

🔐 OAuth Flow Implementation

Installation Process Flow

sequenceDiagram
    participant Merchant
    participant ShopRenter

    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:

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

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.

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):

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,
      store_url: `https://${shopDomain}`,
      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

Note: The complete OAuth implementation including token refresh, HMAC validation, and credential storage is available in the deployed Edge Functions. The code examples above are simplified for documentation purposes.

🔒 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

# .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!

- 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

// 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:

-- 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:

-- 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'
