Stripe Payment Gateway With Pro Sites

Using Stripe as our payment gateway, when I process a test payment, the end result is that the page refreshes and asks again for payment information. I added the webhook to my Stripe account (http://{{mywebsite}}.com/wp-admin/admin-ajax.php?action=psts_stripe_webhook). Our Stripe is set up correctly - We are using the test keys in the proper fields. The only thing we aren't doing is using an SSL yet - But we have selected the option of "No SSL" in the Payment Gateway settings and using Test Credentials from Stripe. Not sure what else to do. I think if we can get this part working, we'll have a successful product. Any additional guidance? Thank you for your help!
