Use Cases​

1. Send Transactional Email​

// Send order confirmation email
await _messageService.SendAsync(new SendMessageRequest
{
    Channel = MessageChannel.Email,
    TemplateCode = "order-confirmation",
    To = customer.Email,
    Variables = new Dictionary<string, object>
    {
        { "OrderNumber", order.Number },
        { "Total", order.Total },
        { "Items", order.Items }
    }
});

2. Send SMS Notification​

// Send OTP via SMS
await _messageService.SendAsync(new SendMessageRequest
{
    Channel = MessageChannel.SMS,
    TemplateCode = "otp-verification",
    To = user.PhoneNumber,
    Variables = new Dictionary<string, object>
    {
        { "Code", otpCode },
        { "ExpiryMinutes", 5 }
    }
});

3. AI Template Generation​

// Generate template from brief
var template = await _templateGenerator.GenerateAsync(new GenerateTemplateRequest
{
    Brief = "Send invoice payment reminder with due date and amount",
    Variables = new[] { "InvoiceNumber", "DueDate", "Amount", "CustomerName" },
    Channels = new[] { MessageChannel.Email, MessageChannel.SMS },
    Tone = "Professional and friendly"
});

4. Telegram Bot Integration​

// Handle Telegram command
await _telegramService.SendMessageAsync(new TelegramMessageRequest
{
    ChatId = chatId,
    Text = "Your order has been shipped! Track it here:",
    InlineKeyboard = new[]
    {
        new[] { new InlineKeyboardButton("Track Order", trackingUrl) }
    }
});

AI Template Generator​

How It Works​

  1. Input: Brief description + variables + channel(s)
  2. Processing: AIHub generates appropriate templates
  3. Output: Channel-specific formatted templates
  4. Review: Admin reviews and approves
  5. Deploy: Templates available for use

Example​

Input:

Brief: "Notify user their payment failed with error message"
Variables: CustomerName, Amount, Currency, ErrorMessage, RetryUrl
Channels: Email, SMS

Output:

Email Template:

<h2>Payment Failed</h2>
<p>Hi {{CustomerName}},</p>
<p>We were unable to process your payment of {{Amount}} {{Currency}}.</p>
<p><strong>Reason:</strong> {{ErrorMessage}}</p>
<p><a href="{{RetryUrl}}">Retry Payment</a></p>
