// ============================================================
// NginxApiClient - Basic Usage Example
// ============================================================
// This example demonstrates:
//   1. Creating a client with manual construction (no DI)
//   2. Listing existing proxy hosts
//   3. Creating a new proxy host
//   4. Updating a proxy host
//   5. Deleting a proxy host
//   6. Error handling
// ============================================================

// Configure the NPM connection
var options = new NginxProxyManagerClientOptions
{
    BaseUrl = "http://localhost:81",  // Your NPM instance URL
    Credentials = new NginxCredentials("admin@example.com", "changeme"),
};

// Create the client — authentication is handled automatically
var serializer = new SystemTextJsonSerializer();
var client = NginxProxyManagerClientFactory.Create(options, serializer);
