fix: Restore Shopify integration functionality

Problem Description

Following the removal of the Vercel backend (see #4), the Shopify OAuth integration and data synchronization features were completely removed. This makes it impossible for merchants to connect their Shopify stores to ShopCall.ai.

Impact

❌ Merchants cannot authenticate with Shopify
❌ Cannot connect new Shopify stores
❌ Cannot sync products, orders, or customer data from Shopify
❌ Webhooks page shows only hardcoded mock data
⚠️ GDPR non-compliant - Missing mandatory Shopify webhooks

Missing Functionality

1. OAuth Authentication Flow

Removed endpoints:

GET /auth/shopify - Initiates OAuth flow
GET /auth/shopify/callback - Handles OAuth callback with authorization code

Features:

HMAC signature validation for security
OAuth state parameter for CSRF protection
Access token exchange
Store credentials encryption in database

2. GDPR Compliance Webhooks ⚠️ CRITICAL

Removed endpoints:

POST /gdpr/customers-data-request - Handle customer data requests
POST /gdpr/customers-redact - Handle customer data deletion
POST /gdpr/shop-redact - Handle shop data deletion

Impact: Non-compliant with Shopify's mandatory GDPR requirements. This will block Shopify App Store approval.

3. Store Management

Missing capabilities:

Store credential storage in Supabase
API connection validation
Store disconnection handling

Technical Specifications

Required Supabase Edge Functions

1. `supabase/functions/oauth-shopify/index.ts`

Purpose: Handle Shopify OAuth flow (initiation + callback)

Endpoints:

GET /oauth-shopify?action=init&user_id={userId} - Start OAuth
GET /oauth-shopify?action=callback&code={code}&shop={shop}&state={state} - Handle callback

Key Features:

Generate OAuth authorization URL with proper scopes
Validate HMAC signature from Shopify
Verify state parameter for CSRF protection
Exchange authorization code for access token
Store credentials securely in stores table
Handle errors (invalid HMAC, missing parameters, etc.)

Required Scopes:

const SHOPIFY_SCOPES = [
  'read_products',
  'read_orders',
  'read_customers',
  'read_inventory',
  'read_price_rules'
];

Security:

HMAC-SHA256 validation using Shopify API secret
State parameter validation
Encrypted credential storage

2. `supabase/functions/webhooks-shopify/index.ts`

Purpose: Handle mandatory GDPR webhooks

Endpoints:

POST /webhooks-shopify?topic=customers/data_request
POST /webhooks-shopify?topic=customers/redact
POST /webhooks-shopify?topic=shop/redact

Implementation Requirements:

Verify webhook HMAC signature
Log all GDPR requests
Process data requests within 30 days (Shopify requirement)
Redact/delete customer data as requested
Remove shop data on app uninstallation

GDPR Compliance:

customers/data_request: Export all customer data in machine-readable format
customers/redact: Delete customer PII within 30 days
shop/redact: Delete all shop data on uninstallation

@fszontagh I'm starting work on this issue now! 🚀

My Plan

I'll implement the Shopify integration restoration in phases:

Phase 1: Database Setup

Create gdpr_requests table migration
Create oauth_states table for OAuth flow state management

Phase 2: OAuth Flow Implementation

Create supabase/functions/oauth-shopify/index.ts with:
- OAuth initiation endpoint (generates authorization URL)
- OAuth callback handler (validates HMAC, exchanges code for token)
- State parameter management for CSRF protection
- Secure credential storage

Phase 3: GDPR Webhooks (Critical for App Store Compliance)

Create supabase/functions/webhooks-shopify/index.ts with:
- customers/data_request handler
- customers/redact handler
- shop/redact handler
- HMAC signature verification
- Request logging and tracking

Phase 4: Frontend Integration

Update Webshops.tsx with "Connect Shopify" functionality
Add OAuth callback handling
Display connected stores
Implement disconnect functionality

Phase 5: Data Sync & API Client

Create Shopify API client library
Implement product, order, and customer sync
Add cache tables similar to WooCommerce/ShopRenter patterns

I'll start with the database migrations and then move through each phase systematically. I'll keep you updated on progress! 👍

feat: Restore Shopify integration functionality #6...

✅ Shopify Integration Restored Successfully!

I've completed the full Shopify integration restoration. All features are now implemented and ready for testing.

📦 What Was Implemented

Phase 1: Database Setup ✅

Created comprehensive database migration (supabase/migrations/20251030_shopify_integration.sql):

- shopify_invalid_state
- shopify_state_expired
- shopify_token_exchange_failed
- shopify_connection_failed
- invalid_shop_domain
✅ Toast notifications for success/failure
✅ Automatic store list refresh after connection

Phase 7: Documentation ✅

Updated CLAUDE.md:

✅ Complete Shopify integration architecture documentation
✅ Database schema for all 6 new tables
✅ OAuth flow documentation
✅ GDPR webhook requirements

📝 Deployment Instructions

Full deployment checklist is in my previous comment, but here's the quick version:

# 1. Run database migration
supabase db push

# 2. Deploy Edge Functions
supabase functions deploy oauth-shopify
supabase functions deploy webhooks-shopify
supabase functions deploy shopify-sync

# 3. Set environment variables in Supabase Dashboard
# SHOPIFY_API_KEY, SHOPIFY_API_SECRET

# 4. Build and deploy frontend
cd shopcall.ai-main && npm run build

✨ What's Next?

The implementation follows the exact same patterns as your existing WooCommerce and ShopRenter integrations, so it should integrate seamlessly with your codebase.

Feel free to:

Test the implementation
Request changes or improvements
Ask questions about any part of the code
Deploy to production when ready

Let me know if you need any adjustments or have questions! 🙌
