title: paypal api permission third party authorization
body: <p>I am developing a third party authorization with Permissions API. </p>
  
  <p>I get the token successfully with the <code>RequestPermissions</code> and <code>GetAccessToken</code> API, but then I don't know how to use <code>TransactionSearch</code> and <code>GetTransactionDetails</code> with the token. </p>
  
  <p>Before I used <code>GetTransactionDetails</code> just with API UserName, API Password, and API Signature, but now when I use the third party, I don't know how to use the token I got with permissions API. Can anyone help me on this?</p>
