title: REST API INTEGRATION WITH APACHE NIFI (Getting data from kafka -transform ->generate token (POST)-> post API )
body: <p>I am trying to create a flow in Apache Nifi - Situation is like this
  1- Consume message from kafka (DONE)
  2- transform to a valid request body (DONE)
  3- Preserve the transformed message
  4- Generate a oauth2 token (it is a post api )
  5- Invoke a post api with transformed json as request body and send token in header</p>
  <p>I have tried few ways like putting transformed json in cache and getting it after token generation but the problem is I am not able to pass token to fetchdistributedcache processor .
  I tried putting json file on my server but getfile doesn't take any input so not able to trigger it after getting token .</p>
