title: A way of checking if a paypal transaction was made
body: <p>I'm trying to find a way of implementing the paypal api in my asp.net project.</p>
  
  <p>Basically, what I'm trying to achieve is to create a page where the user sends the money and a page where the payment is checked.</p>
  
  <p>I wasn't able to find a way of checking the payment.</p>
  
  <p>It's an important step in my project because I need to check if the payment was made in order to insert some data into a SQL database and I don't want the database to be exploited using the payment/checking method.</p>
  
  <p>Can someone guide me?</p>
  
  <p>Thanks in advance,</p>
