Configure your endpoint to return 200 status codes for successful receipts
Use standard ports (80 for HTTP or 443 for HTTPS only)
Common Solutions:
Verify your endpoint is publicly accessible
Check for proper response codes
Ensure proper port configuration
Monitor webhook logs for detailed error information
