#11 feat: Implement WooCommerce OAuth 1.0a authentication flow

Overview

Implement WooCommerce OAuth 1.0a authentication as a Supabase Edge Function to enable merchants to securely connect their WooCommerce stores to ShopCall.ai.

Context

This is part of restoring WooCommerce integration after Vercel backend removal (#4). The backend must now use Supabase Edge Functions.

Implementation Requirements

Edge Function: oauth-woocommerce

Location: supabase/functions/oauth-woocommerce/index.ts

Endpoints:

• GET /oauth-woocommerce?action=init&user_id={userId}&store_url={storeUrl}

  • Validate store URL format (must be https://)
  • Check store reachability
  • Generate WooCommerce OAuth authorization URL
  • Return authorization URL to frontend
    

• GET /oauth-woocommerce?action=callback&success={1|0}&user_id={userId}&...

  • Handle OAuth callback from WooCommerce
  • Extract consumer key and secret
  • Validate callback parameters
  • Test API connection with credentials
  • Store credentials in stores table
  • Redirect to frontend with success/error

OAuth 1.0a Implementation

Required functionality:

• HMAC-SHA256 signature generation
• OAuth parameter normalization
• Signature base string generation
• Timestamp and nonce generation

WooCommerce permissions:

const WC_SCOPES = [
  'read_products',
  'read_orders', 
  'read_customers',
  'read_coupons',
  'read_reports'
];

API Connection Testing

After receiving credentials, validate with:

GET {store_url}/wp-json/wc/v3/system_status

Database Integration

Store credentials in stores table:

{
  user_id: UUID,
  platform_name: 'woocommerce',
  store_name: string,
  store_url: string,
  api_key: string,        // Consumer key
  api_secret: string,      // Consumer secret
  scopes: string[],
  alt_data: {
    wcVersion: string,
    wpVersion: string,
    apiVersion: 'wc/v3',
    lastSync: timestamp
  }
}

Error Handling

Handle these scenarios:

• Invalid store URL format
• Unreachable store
• OAuth rejection by merchant
• Invalid credentials
• API connection failures
• Missing WooCommerce installation

Environment Variables

Required in Supabase Edge Functions:

WC_CALLBACK_URL=https://ztklqodcdjeqpsvhlpud.supabase.co/functions/v1/oauth-woocommerce?action=callback
FRONTEND_URL=https://shopcall.ai
WC_APP_NAME=ShopCall.ai
SUPABASE_URL=https://ztklqodcdjeqpsvhlpud.supabase.co
SUPABASE_SERVICE_ROLE_KEY={key}

Shared Library

Create supabase/functions/_shared/woocommerce-client.ts with:

• OAuth 1.0a signature generation utilities
• WooCommerce API client class
• Request signing helper functions
• Error handling utilities

Security Requirements

• ✅ OAuth 1.0a signature validation
• ✅ HTTPS-only store URLs
• ✅ Secure credential storage
• ✅ API endpoint reachability verification
• ✅ Request signature verification

Testing Checklist

• OAuth initiation generates valid authorization URL
• Store URL validation works correctly
• Unreachable stores handled gracefully
• OAuth callback extracts credentials correctly
• API connection test succeeds with valid credentials
• Credentials stored correctly in database
• Error scenarios handled properly
• Frontend redirect works after OAuth

Success Criteria

• Merchants can initiate OAuth flow with store URL
• OAuth redirects to WooCommerce admin correctly
• Callback handler receives and validates credentials
• API connection tested before saving
• Credentials stored securely in Supabase
• Frontend receives success/error response

Implementation Status Update

I've reviewed the current codebase and found that WooCommerce OAuth 1.0a authentication has already been fully implemented. Here's what exists:

✅ Completed Components

1. Edge Function - supabase/functions/oauth-woocommerce/index.ts

   • ✅ OAuth initiation endpoint (action=init)
   • ✅ OAuth callback endpoint (action=callback)
   • ✅ Store URL validation (HTTPS enforcement)
   • ✅ CSRF protection with state parameter
   • ✅ API connection testing before credential storage
   • ✅ Secure credential storage in stores table
   • ✅ Proper error handling and redirects

2. Shared Library - supabase/functions/_shared/woocommerce-client.ts

   • ✅ OAuth 1.0a signature generation utilities
   • ✅ WooCommerce API client functions
   • ✅ Request signing with HMAC-SHA256
   • ✅ Helper functions for products, orders, customers

• The WooCommerce OAuth 1.0a implementation was fully completed (commit 1b10b41)
• The Edge Function is deployed and ACTIVE
• All requirements were verified and met
• The issue was previously closed as complete

Since this has been re-assigned, I'll now verify the current state of the implementation and check if any updates or improvements are needed. Let me examine the code and deployment status to ensure everything is still functioning correctly.
