title: How to get PayPal TransactionID via eBay API
body: <p>I need to get PayPal TransactionID of the paid order on eBay via API.</p>
  
  <p>I use ExternalTransaction like described here: <a href="https://ebay.custhelp.com/app/answers/detail/a_id/1550/~/linking-ebay-and-paypal-transactions" rel="nofollow">https://ebay.custhelp.com/app/answers/detail/a_id/1550/~/linking-ebay-and-paypal-transactions</a></p>
  
  <pre><code>    ExternalTransactionType[] externalTransactionTypeArr = transactionType.ExternalTransaction;
  </code></pre>
  
  <p>but eBay API always returns null as transactionType.ExternalTransaction</p>
  
  <p>Any suggestions?</p>
  
  <p>Thanks!</p>
