  "shippingPostCode": "SW1A 1AA"
}

Phase 4: Payment Integration with SilverPay

Test	Status	Error	Details
Create Payment	❌ FAIL	Failed to create SilverPAY order: NotFound	SilverPay service not accessible

Error Stack Trace:

System.InvalidOperationException: Failed to create payment: Failed to create SilverPAY order: NotFound
 ---> System.InvalidOperationException: Failed to create SilverPAY order: NotFound
   at LittleShop.Services.SilverPayService.CreateOrderAsync(...) in SilverPayService.cs:line 137

API Request Details:

• Endpoint: POST http://10.0.0.51:5500/api/v1/orders
• Request Body:

  {
    "external_id": "order-d89e1f19-95a4-4d4c-804c-c65f5c6d6834",
    "fiat_amount": 59.98,
    "fiat_currency": "GBP",
    "currency": "BTC",
    "webhook_url": "http://localhost:5000/api/orders/payments/webhook",
    "expires_in_hours": 24
  }
  

Troubleshooting Steps Required:

1. Verify SilverPay service is running: curl http://10.0.0.51:5500/api/health
2. Check network connectivity from development machine to 10.0.0.51:5500
3. Verify API endpoint path: /api/v1/orders vs other possible paths
4. Check SilverPay logs for request arrival
5. Verify API authentication (API key: OCTk42VKenf5KZqKDDRAAskxf53yJsEby72j99Fc)

Phase 5: Bot Activity Tracking Performance

Metric	Before Fix	After Fix	Improvement
Single Call	3000ms+ (timeout)	34.63ms	86x faster
Rapid Call #1	3000ms+	5.81ms	516x faster
Rapid Call #2	3000ms+	6.65ms	451x faster
Rapid Call #3	3000ms+	4.77ms	629x faster
Average	3000ms+	5.74ms	523x faster

Fix Details:

• File: TeleBot/TeleBot/Services/BotActivityTracker.cs
• Line: 39
• Change: configuration["LittleShop:BaseUrl"] → configuration["LittleShop:ApiUrl"]
• Fallback: "http://littleshop:5000" → "http://localhost:5000"

Before:

_littleShopUrl = configuration["LittleShop:BaseUrl"] ?? "http://littleshop:5000";
// ❌ Config key didn't exist, fell back to Docker hostname causing DNS failures

After:

_littleShopUrl = configuration["LittleShop:ApiUrl"] ?? "http://localhost:5000";
// ✅ Correctly reads from appsettings.json, uses localhost fallback

Issues Identified

1. ✅ RESOLVED: Bot Activity Tracking Slowness (CRITICAL)

Severity: CRITICAL Status: ✅ FIXED Impact: Every user interaction delayed by 3+ seconds

Root Cause: Configuration key mismatch in BotActivityTracker.cs caused DNS resolution failures for non-existent littleshop:5000 hostname.

Error Logs:

[17:21:13 INF] Start processing HTTP request POST http://littleshop:5000/api/bot/activity
[17:21:16 ERR] Error tracking bot activity
System.Net.Http.HttpRequestException: No such host is known. (littleshop:5000)
System.Net.Sockets.SocketException (11001): No such host is known.

Resolution:

• Updated BotActivityTracker.cs:39 to use correct configuration key
• Changed fallback from Docker hostname to localhost
• Rebuilt and tested TeleBot
• Verified performance improvement: 3000ms → 5.74ms (523x faster)

Verification:

# Before fix:
Call 1: 3000ms+ (timeout)
Call 2: 3000ms+ (timeout)
Call 3: 3000ms+ (timeout)

# After fix:
Call 1: 5.81ms
Call 2: 6.65ms
Call 3: 4.77ms
Average: 5.74ms ✅

2. ❌ OPEN: SilverPay Payment Gateway Not Accessible (HIGH)

Severity: HIGH Status: ❌ OPEN Impact: Payment creation fails for all orders

Root Cause: SilverPay service at http://10.0.0.51:5500 is not responding to HTTP requests.

Error:

Failed to create SilverPAY order: NotFound (HTTP 404)

Required Actions:

1. Verify SilverPay service is running on 10.0.0.51:5500
2. Check network routing from development machine to SilverPay host
3. Verify API endpoint path and authentication
4. Check SilverPay API logs for incoming requests
5. Confirm API key is valid: OCTk42VKenf5KZqKDDRAAskxf53yJsEby72j99Fc

Workaround: Payment creation can be mocked/stubbed for local development and testing of the Telegram bot order flow.

3. ℹ️ INFO: Health Endpoint Missing on TeleBot (LOW)

Severity: LOW Status: ℹ️ INFORMATIONAL Impact: None - health checks are optional for bot services

Details: TeleBot returns 404 for /health endpoint. This is expected behavior as the bot doesn't expose a standard health endpoint.

Recommendation: Consider adding a simple health endpoint for monitoring and E2E testing purposes.

4. ℹ️ INFO: Order Creation Requires All Shipping Fields (LOW)

Severity: LOW Status: ℹ️ INFORMATIONAL Impact: API validation prevents incomplete orders

Details: Order creation API requires all shipping fields (shippingName, shippingAddress, shippingCity, shippingPostCode). The E2E test initially failed due to missing fields.

Resolution: Updated E2E test script with complete order payload. This is correct behavior - shipping details are required for order fulfillment.

Conclusion

The E2E integration testing successfully identified and resolved a critical performance issue affecting all user interactions with the TeleBot. The bot activity tracking performance improved by 523x (from 3000ms+ to 5.74ms average).

The primary remaining issue is SilverPay connectivity, which prevents payment creation. This requires infrastructure investigation to determine why the payment gateway at http://10.0.0.51:5500 is not accessible from the development environment.

Next Steps:

1. ✅ Commit and push the BotActivityTracker fix
2. 🔴 Investigate SilverPay connectivity issue
3. 🔴 Verify SilverPay service status on host 10.0.0.51
4. 🔴 Test payment creation once SilverPay is accessible
5. ✅ Monitor bot performance in production
