title: Cards declined because of authentication
body: <p>I'm using stripe to manage payments on my site and it works fine when I'm using dummy cards that don't require authentication but when I use them I get an error.</p>
  
  <p>I'm using test version of stripe to do everything so I don't know are the errors occurring because of that or there is something else that is causing the cards to be declined.</p>
  
  <pre><code>@csrf_exempt
  def charge(request):
      if request.method == 'POST':
          charge = stripe.Charge.create(
              amount=int(str(request.POST["am"])),
              currency='usd',
              description=str(request.POST['desc']),
              source=request.POST['stripeToken'],
         )
          return redirect("pay_app:completed")
