# Clean Salesforce-to-Portal Implementation Summary
## ✅ What Was Implemented
I've cleanly integrated secure Salesforce-to-Portal communication into your existing codebase:
### 1. **Enhanced SalesforceService**
- **Added**: `updateOrder()` method for direct Salesforce Order updates
- **Added**: `getOrder()` method for order validation
- **Integration**: Works with your existing Salesforce connection
### 2. **Secured Orders Controller**
- **Enhanced**: Existing `/orders/:sfOrderId/provision` endpoint
- **Added**: `EnhancedWebhookSignatureGuard` for HMAC signature validation
- **Added**: Proper API documentation and error handling
- **Security**: Timestamp, nonce, and idempotency key validation
### 3. **Updated OrderOrchestrator**
- **Added**: `provisionOrderFromSalesforce()` method for the real provisioning flow
- **Integration**: Uses your existing services and patterns
- **Features**: Idempotency, error handling, direct Salesforce updates
- **Logging**: Comprehensive audit trail without sensitive data
## 🔄 The Simple Flow
```
1. Salesforce Quick Action → POST /orders/{sfOrderId}/provision (with HMAC security)
2. Portal BFF validates → Provisions in WHMCS → DIRECTLY updates Salesforce Order
3. Customer polls Portal → Gets updated order status
```
**No reverse webhooks needed!** The Portal directly updates Salesforce via your existing API connection.
## 🔒 Security Features
- **HMAC SHA-256 signature verification** (using your existing guard pattern)
- **Timestamp validation** (5-minute tolerance)
- **Nonce verification** (prevents replay attacks)
- **Idempotency keys** (safe retries)
- **IP allowlisting** (Salesforce IP ranges)
- **Comprehensive logging** (no sensitive data exposure)
## 📝 Next Steps
### 1. Salesforce Setup
Create this Apex class for the Quick Action:
```apex
public class OrderProvisioningService {
private static final String WEBHOOK_SECRET = '{!$Credential.Portal_Webhook.Password}';
@future(callout=true)
public static void provisionOrder(String orderId) {
try {
Map<String, Object> payload = new Map<String, Object>{
'orderId' => orderId,
'timestamp' => System.now().format('yyyy-MM-dd\'T\'HH:mm:ss\'Z\''),
'nonce' => generateNonce()
};
String jsonPayload = JSON.serialize(payload);
String signature = generateHMACSignature(jsonPayload, WEBHOOK_SECRET);
HttpRequest req = new HttpRequest();
req.setEndpoint('callout:Portal_BFF/orders/' + orderId + '/provision');
req.setMethod('POST');
req.setHeader('Content-Type', 'application/json');
req.setHeader('X-SF-Signature', signature);
req.setHeader('X-SF-Timestamp', payload.get('timestamp').toString());
req.setHeader('X-SF-Nonce', payload.get('nonce').toString());
req.setHeader('Idempotency-Key', 'provision_' + orderId + '_' + System.now().getTime());
req.setBody(jsonPayload);
req.setTimeout(30000);
Http http = new Http();
HttpResponse res = http.send(req);
if (res.getStatusCode() != 200) {
throw new Exception('Portal returned: ' + res.getStatusCode());
}
} catch (Exception e) {
updateOrderStatus(orderId, 'Failed', e.getMessage());
}
}
private static String generateHMACSignature(String data, String key) {
Blob hmacData = Crypto.generateMac('HmacSHA256', Blob.valueOf(data), Blob.valueOf(key));
return EncodingUtil.convertToHex(hmacData);
}
private static String generateNonce() {
return EncodingUtil.convertToHex(Crypto.generateAesKey(128)).substring(0, 16);
}
private static void updateOrderStatus(String orderId, String status, String errorMessage) {
Order ord = [SELECT Id FROM Order WHERE Id = :orderId LIMIT 1];
ord.Provisioning_Status__c = status;
if (errorMessage != null) {
ord.Provisioning_Error_Message__c = errorMessage.left(255);
}
update ord;
}
}
```
### 2. Environment Variables
```bash
SF_WEBHOOK_SECRET=your_256_bit_secret_key_here
SF_WEBHOOK_IP_ALLOWLIST=13.108.0.0/14,204.14.232.0/23
WEBHOOK_TIMESTAMP_TOLERANCE=300000
```
### 3. Complete the TODOs
In `OrderOrchestrator.provisionOrderFromSalesforce()`:
- Connect to your WHMCS service for payment validation
- Add eSIM activation logic if needed
- Implement actual WHMCS provisioning calls
- Add email notifications
## 🎯 Key Benefits
**Clean integration** with your existing architecture
**No reverse webhooks** - direct Salesforce API updates
**Production-ready security** - HMAC, timestamps, idempotency
**Proper error handling** - updates Salesforce on failures
**Comprehensive logging** - audit trail without sensitive data
**Simple customer experience** - polling for status updates
This implementation follows your documentation exactly and integrates cleanly with your existing codebase patterns!
