  • Charge Credit Cards (13:48)

    Once Stripe returns a valid token, write the code to charge a user's credit card. Verify that the payment went through in your Stripe dashboard.

  • Collect Bank Account Info (7:02)

“I personally and wholeheartedly recommend this for anyone who wants to jump in with both feet and learn as you go by creating an actual application that you can use and or modify for your own use.” - William P.

"I created my own demo website and deployed to Heroku in 2 days. Alex explained eveything you need when you start Ruby on Rails: installing gems, facing problems on Ruby, creating lists, bootstrap designs, uploading images, Git version control, deploying on Heroku. I'm waiting for more lectures/courses from Alex." - Volkan G.

"I just finished your course, and I loved every minute of it. It's amazing how much I've learned in just a couple of days, and I'm excited to continue learning more and applying the skills I gained from watching your videos." - Matthew F.
