I would suggest building JSON using a JSON serializer, as it's much less error-prone.

Using JSON.NET:

var body = JsonConvert.SerializeObject(new {
    CompanyDB = "abc",
    UserName = "def",
    Password = "ghi"
});

If you need to have the response formatted with newlines for some reason, you can pass Formatting.Indented to SerializeObject as the second argument.

Using System.Text.Json:

var body = JsonSerializer.Serialize(new {
    CompanyDB = "abc",
    UserName = "def",
    Password = "ghi"
});

If you need to have the response formatted with newlines for some reason, you can pass new JsonSerializerOptions() { WriteIndented = true } to Serialize as the second argument.
