title: How to call REST API with Oauth Header in Apache Camel?
body: <p>I am consuming an API with OAuth1.0 authorization. I want to make call to that API with the authorization Oauth header:-<br>
  I have created the authorization header from the token/key received from the server using- (ConsumerKey,keyalias and password) and want to send back the token or the OAuth header with the call.</p>
  
  <p>I have did all these things in a Processor(Class implementing Camel Processor) and now want to do:-</p>
  
  <ol>
  <li>Either call the rest API with this Oauth header(of type String) in the processor itself.</li>
  <li>Else send this header in exchange and get this value in camel's <code>to()</code> endpoint and then in it call the REST API.</li>
  </ol>
  
  <p>Thing is i just want to make rest a call in <strong>processor</strong> with Oauth header. 
  And then if possible try to access the header in <code>to()</code> endpoint and make the call.</p>
