Going Live

From the technical point of view you need to make sure to load SubscriptionJS from the Live Instance of billwerk

<script type="text/javascript" src="https://selfservice.billwerk.com/subscription.js"></script>

Get your publicApiKey from the live settings and update your code accordingly.

paymentService = new SubscriptionJS.Payment({ publicApiKey : "527cc4c951f45b08c493d834" }...

Also update your plan variant ids and component ids. When done with the technical todos make sure the PSP settings on the Live System are ready to do real payments. Make at least one real life test for each supported payment method.
