Can't import a certificate via XML API using C#

Hello,

I'm trying to import a certificate to a Palo Alto VM-50 via XML API with an App written in C# but I always get this error:

<response status = 'error' code = '400'><result><msg>No file uploaded</msg></result></response>

My C# code is below, I can't see where the problem is, if I use this curl command the file gets uploaded successfully:

curl --insecure --header "Authorization:Basic myauth" -F "file=@testCA.crt" "https://10.16.66.229/api?type=import&category=certificate&certificate-name=TestCA&format=pem"

Any ideas?

using System; using System.IO; using System.Net.Http; using System.Net.Http.Headers; using System.Text; using System.Threading.Tasks; namespace TestUploadPA { internal class Program { static async Task Main(string[] args) { string url = "https://10.16.66.229/api/?type=import&category=certificate&certificate-name=TestCA&format=pem"; string filePath = "testCA.crt"; string username = "myuser"; string password = "mypass"; var handler = new HttpClientHandler { ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => true, }; using (HttpClient client = new HttpClient(handler)) { client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic", Convert.ToBase64String(Encoding.ASCII.GetBytes(username + ":" + password))); using (var formData = new MultipartFormDataContent()) using (var fileContent = new ByteArrayContent(File.ReadAllBytes(filePath))) { fileContent.Headers.ContentType = new MediaTypeHeaderValue("application/octet-stream"); formData.Add(fileContent, "file", Path.GetFileName(filePath)); HttpResponseMessage response = await client.PostAsync(url, formData); if (response.IsSuccessStatusCode) { string content = await response.Content.ReadAsStringAsync(); Console.WriteLine($"XML result: {content}"); } else { Console.WriteLine($"Error uploading file. Status code: {response.StatusCode}"); } } } } } }

Hello,

I managed to figured out what was wrong: the boundary in the multipart/form-data content-type header was being double quoted. I added some code to remove the quotes and I was able to import the certificate to the Palo Alto firewall successfully.
