I'm trying to upload binaries in the new Web 8 way. (i've got a few gigs worth to upload).

Each time I try and upload a file, I run the following code:

StreamUploadClient _UploadClient = null;
_UploadClient = new StreamUploadClient(_endpointConfigNameUpload);
var userCredential = new System.Net.NetworkCredential(_username, _password, _domain);                                 _UploadClient.ClientCredentials.Windows.ClientCredential = userCredential;
AccessTokenData token = CoreServiceClient.GetCurrentUser();

fileUpload = _UploadClient.UploadBinaryContent(token, file.OpenRead());

and once the component is saved, I do the following:


After a few mins I get an error that :

Couldn't upload the binary file Provided access token has expired

I have performed the 2013 compatibility in my CME hoping this would stop the token from expiring (http://docs.sdl.com/LiveContent/web/pub.xql?action=home&pub=SDL%20Web-v1&lang=en-US&docid=GUID-879B67A8-71BA-4BBD-9CCE-9140B860904E&query=%2B%22AccessTokenData%22)

I've also tried adding 24 hours to the token via the token.ExpiresAt(DateTime)

But none of these changes help me with my issue. Has anyone got any advice?

Thanks in advance.

  • hi John, i had same issue, my work around is renew the access token if it will expire in the next 30 seconds. if (accessToken.ExpiresAt <= DateTime.Now.AddSeconds(30)) works for me

  • Access Tokens expire for security reasons.. Obviously, you can't make them expire later by simply changing the expiration date/time in the Access Token; that would defeat the purpose of expiration. Commented Dec 23, 2016 at 14:33

the quick way is checking expireAt from the access token, close current client if expires in 30 seconds and create an new client.

    public void UpdateAccessToken()
        AccessTokenData accessToken = client.GetCurrentUser();
        if (accessToken.ExpiresAt <= DateTime.Now.AddSeconds(30))

    Lucas, see tridion.stackexchange.com/questions/14996/… on how to configure the default value and avoid the constant round-tripping here (you may still want this if you want specific events to 'refresh' the token I guess). Commented Jun 29, 2016 at 14:17
  • i didn't get that value to work @Dylan..MarkSaunders

  • ahh that's a shame - I'll leave it here for a few days in case Kunal updates (perhaps a specific restart or something along those lines is required) .. otherwise I'll delete the link :-/ Commented Jun 29, 2016 at 22:34
  • i cannot change the timeout value on SDL Cloud, but have to detect expiry time plus 30 seconds (time to call back). this works...
