        }
      }
    }
  }
}

Using the Email Service

The email service uses a factory pattern to support multiple providers:

csharp

public interface IEmailService
{
    Task<IEmailResponse> SendEmailAsync(IEmailMessage message, CancellationToken ct = default);
    Task<IEmailResponse> SendEmailAsync(IEmailMessage message, string providerName, CancellationToken ct = default);
}

// Usage in controller
public class NotificationController : ControllerBase
{
    private readonly IEmailService _emailService;

    [HttpPost("send")]
    public async Task<IActionResult> SendNotification([FromBody] EmailRequest request)
    {
        var message = new EmailMessage
        {
            To = new[] { new EmailRecipient(request.Email, request.Name) },
            Subject = request.Subject,
            HtmlContent = request.Body
        };

        var result = await _emailService.SendEmailAsync(message);

        if (result.Success)
            return Ok(new { messageId = result.MessageId });
        else
            return BadRequest(new { error = result.ErrorMessage });
    }
}

Service Registration

Email Service

csharp

// In Startup.cs or Program.cs
services.AddEmailService(Configuration, "Email");

Stripe Services

csharp

services.AddScoped<IStripePayService, StripePayService>();
services.AddScoped<IStripeConnectService, StripeConnectService>();
services.AddScoped<IStripeSubscriptionService, StripeSubscriptionService>();

Azure Services

csharp

services.AddScoped<IAzureWebAppService, AzureWebAppService>();
services.AddScoped<IAzureDocumentIntelligenceService, AzureDocumentIntelligenceService>();

OpenAI Services

csharp

services.AddScoped<IOpenAIService, OpenAIService>();
services.AddScoped<IAzureOpenAIService, AzureOpenAIService>();

Error Handling

All services return structured responses:

csharp

public interface IEmailResponse
{
    bool Success { get; }
    string ProviderName { get; }
    string? MessageId { get; }
    string? ErrorMessage { get; }
    int? StatusCode { get; }
}

Best Practices

Use environment variables - Don't commit API keys to source control
Configure fallback providers - Set up multiple email providers
Handle failures gracefully - Log errors and notify admins
Use webhooks - For payment confirmations and email events
Monitor usage - Track API calls and costs
