title: Paypal valid card types
body: <p>I realize that this question is off-topic for this site but I followed a link to the Paypal developer forum on <a href="https://developer.paypal.com/webapps/developer/support" rel="nofollow">this page</a> and it brought me here.</p>
  
  <p>I just need a list of valid payment card types when adding a card to the vault as documented <a href="https://developer.paypal.com/webapps/developer/docs/integration/direct/store-a-credit-card/#store-a-credit-card" rel="nofollow">here</a></p>
  
  <p>I've not turned up anything with a Google search, if someone could provide a link to a resource I'd be grateful</p>
