Hello,

Here is a sample code snippet for logging into UpStox using a C# application (utilizing the UpStox SDK). An explanation of the code is provided below.

string url = "http://localhost:11400/";
var listener = new HttpListener();
listener.Prefixes.Add(url);
listener.Start();
btnContinue.Enabled = false;
UpStoxClient.Api.LoginApi api = new UpStoxClient.Api.LoginApi();
// Open login page in default browser
ProcessStartInfo psi = new ProcessStartInfo
{
    FileName = $"https://api.upstox.com/v2/login/authorization/dialog?client_id={UrlEncoder.Default.Encode(Program.UpStoxAPIKey)}&redirect_uri=" + UrlEncoder.Default.Encode(url),
    UseShellExecute = true
};
Process.Start(psi);
var context = await listener.GetContextAsync();
string response = "UpStox Login successful!";
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(response);
context.Response.OutputStream.Write(buffer, 0, buffer.Length);
context.Response.OutputStream.Close();
string query = context.Request.Url.Query;
listener.Stop();
// Parse the query string
var queryParams = HttpUtility.ParseQueryString(query);

if (queryParams.HasKeys())
{
    // Get the value of "apisession"
    string code = queryParams["code"];
    if (!string.IsNullOrEmpty(code))
    {
        TokenResponse tokenResp = api.Token(code, Program.UpStoxAPIKey, Program.UpStoxAPISecret, url, "authorization_code");
        Program.UpStoxToken = tokenResp.AccessToken;
        Configuration.Default.AccessToken = tokenResp.AccessToken;
        this.Focus();
    }
    else
    {
        btnContinue.Enabled = true;
        MessageBoxAdv.Show("UpStox login failed.", "", MessageBoxButtons.OK, MessageBoxIcon.Error);
        return;
    }
}

  1. Setup Local HTTP Listener:

    • A local HTTP server is started using HttpListener to listen on a specific URL (e.g., http://localhost:11400/).
    • This URL acts as the redirect_uri where UpStox will send the callback after successful login.

  2. Redirect URL in UpStox API:

    • Yes, you need to register the same redirect_uri (e.g., http://localhost:11400/) in your UpStox API configuration to ensure UpStox redirects to this URL after user authentication.

  3. Open Login Page:

    • The application constructs the UpStox login URL with necessary parameters like:
      • client_id (API key from UpStox).
      • redirect_uri (the registered URL where UpStox will send the callback).
    • Opens this URL in the default browser, prompting the user to log in.

  4. Wait for Callback:

    • The HttpListener waits for the UpStox API to redirect the user to the redirect_uri after login.
    • Once redirected, the authorization code is included in the query string of the URL.

  5. Extract Authorization Code:

    • The application extracts the code parameter from the callback URL query string, which serves as the authorization code.

  6. Exchange Code for Access Token:

    • The authorization code is sent to UpStox’s API along with:
      • client_id (API key).
      • client_secret. (API Secret)
      • redirect_uri. (The registered redirect URL)
    • The API responds with an access token if the code is valid.

  7. Store the Access Token:

    • The access token is saved for use in subsequent API requests to UpStox, enabling authenticated operations.

  8. Error Handling:

    • If the code parameter is missing or invalid, an error is displayed, and the process is halted.

Hope it helps.

Thanks

Hi,

Thank you for the code snippet. Its working for my app token generation.
But the same is not working for sandbox app client id token generation. Please let me know the difference if any.

Hello,

Please note that the API URL for the sandbox is different from the production. Please change the URL to sandbox API. Refer to Sandbox | Upstox Developer API

Thanks,

https://api-sandbox.upstox.com/v2/login/authorization/dialog
is it correct for the sandbox. I tried by replacing in your sample. but not working.

{“status”:“error”,“errors”:[{“errorCode”:“”,“message”:“Required String parameter ‘ucc’ is not present”,“propertyPath”:“ucc”,“invalidValue”:null,“error_code”:“”,“property_path”:“ucc”,“invalid_value”:null}]}
