Rest call for Google API

[Anonymous]

Hi all,
I just started using Talend.And i am having a little trouble in finding the components needed for a scenario where i need to do both post and get requests using OAuth. So can somebody share some ideas on how to use the java library(provided by Google APIs client libraries) to do OAuth 2.0 authorization for the rest call. 
Thanks for all the helps,
SJ

Hi Sabrina,
Thanks for the suggestion. I tried to implementing the job as described in the link. But somehow the first time token is not getting generated rather throws an error as "s://accounts.google.com/o/oauth2/auth?scope=
400|{
  "error" : "invalid_grant",
  "error_description" : "Code was already redeemed.""
Any idea whats causing the error?
Thanks again for the help.
