Automate Refresh LinkedIn Tokens for n users without the users being signed in

Hi ,

I am building a WebService in which there are access tokens stored for 10 LinkedIn Users. After 60 days , how do I automate refresh of access tokens without the users being signed in? I know there is a ReconnectFilter that catches expired tokens but then I have to manually do the OAUTH 2.0 dance everytime. I was thinking that there should be some other way to do it?

Is there any API I can use for it? Is there any other way to do it

Thanks and Regards,
Neil
