Google analytics refresh token

Hi, 

I'm calling URI on google API for having data from google analytics thanks to Get resource (batch) node. On my URI I have at the end of the query a token, but the pb is that token is available only for 60 minutes.

Anyone has already deals with this kind of problematics ? I saw on the web refresh_token... any idea how to implement this on knime ?

Thanks for your answers by advance !
