title: Adding SCA on Stripe gateway
body: <p>I have an application and using Stripe Noback-end API for handling payments like this:</p>
  
  <pre><code>stripe.tokens.create({
      card: {
          "number": request.full_card_number,
          "exp_month": request.exp_month,
          "exp_year": request.exp_year,
          "cvc": request.cvc
      }
  }, function(err, token) {
      if (err) {
          resp.json(err)
      } else {
          stripe.charges.create({
              amount: request.amount,
              currency: request.currency,
              source: token.id,
              description: request.description,
              capture: true
          }, function(err, charge) {
              if (err) {
                  resp.json(err)
              } else {
                  resp.json(charge)
              }
          });
      }
  });
  </code></pre>
  
  <p>This will handle the payments really cool by back-end codes. But now we should add SCA to our apps. How can I add SCA and verify step on gateway and still using back-end API on my app?</p>
