# Apply Brand Settings with projectId

This snippet mirrors the [brand settings recipe](/quick-start/quizzes/brand-with-project-id.md) with `outputType: "quiz"`.

```csharp
// Requires .NET 7+ for raw string literals.
using System;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;

var token = Environment.GetEnvironmentVariable("AUTOCONTENT_TOKEN") ?? "YOUR_API_TOKEN";
var endpoint = "https://api.autocontentapi.com/content/Create";

var payloadJson = """
{
  "outputType": "quiz",
  "projects": ["YOUR_PROJECT_ID"],
  "topic": "Customer success onboarding playbook",
  "text": "Focus on product milestones and include 1 trick question.",
  "quizDifficulty": "medium"
}
""";

using var client = new HttpClient();
using var request = new HttpRequestMessage(HttpMethod.Post, endpoint)
{
    Content = new StringContent(payloadJson, Encoding.UTF8, "application/json")
};
request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token);

var response = await client.SendAsync(request);
var body = await response.Content.ReadAsStringAsync();

if (!response.IsSuccessStatusCode)
{
    Console.Error.WriteLine("Request failed: " + (int)response.StatusCode + " " + response.ReasonPhrase);
    Console.Error.WriteLine(body);
    Environment.Exit(1);
}

Console.WriteLine("Quiz request accepted:");
Console.WriteLine(body);
```

Set `YOUR_API_TOKEN` (or `AUTOCONTENT_TOKEN`) before running.
