This extension lets you easily setup a payment form with strip integration. No credit-card data will ever touch Webpop's servers, so Stripe can take care of just about all the PCI compliance for you.
Sign up with Stripe, and find your credentials (the public key and the secret key.).
In the index.tpl file above you need to replace YOUR PUBLIC STRIPE KEY with your public key. In the stripe.js extension you should replace YOUR SECRET STRIPE KEY with your secret key.
To set the amount to charge, change the "amount" attribute for the <pop:stripe:charge>
tag.
You can also add attributes to set "currency" and "description" on the <pop:stripe:charge>
tag.
