title: What happen if I did not use GetExpressCheckoutDetails and DoExpressCheckoutPayment API call
body: <p>I am first time working with paypal.
  After going through all the documentation I have found the following way(API Calls) to create a recurring subscription.</p>
  
  <p>SetExpressCheckout->GetExpressCheckoutDetails->DoExpressCheckoutPayment->CreateRecurringPaymentsProfile.</p>
  
  <p>I have worked in sandbox environment and I did the following thing.</p>
  
  <p>SetExpressCheckout-> Redirected to Url with token</p>
  
  <p><a href="https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&amp;token=xxxx" rel="nofollow">https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&amp;token=xxxx</a></p>
  
  <p>logged in using my sandbox paypal account.</p>
  
  <p>click on agree and continue.</p>
  
  <p>Took token from the above and Passed to CreateRecurringPaymentsProfile API.</p>
  
  <p><strong>The above process which I followed is working correctly and I am able to see the deduction of amount in one account and addition of amount in another account (amount is specified in API call)</strong>.</p>
  
  <p>So what If I did not called GetExpressCheckoutDetails and DoExpressCheckoutPayment.</p>
  
  <p><strong>Specially DoExpressCheckoutPayment(What if did not used).</strong></p>
