var apiId = Environment.GetEnvironmentVariable("HCTI_API_ID")!;
var apiKey = Environment.GetEnvironmentVariable("HCTI_API_KEY")!;
using var client = new HttpClient();
var credentials = Convert.ToBase64String(Encoding.ASCII.GetBytes($"{apiId}:{apiKey}"));
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", credentials);

var request = new
