Billwerk+ offers an administration dashboard, where you have access to all information about your payments and subscriptions.

Additionnaly, our platform also provides you direct integration with your own system. This is done through two primary technologies:

• API
• Webhooks

---

💻 API

The Billwerk+ platform exposes a full API (Application Programming Interface). This gives you the ability to call Billwerk+ Payments or Billwerk+ Subscription Management (Lite/ Expert) from your server-side code and retrieve and update data.

You can integrate API calls into your website or your backend systems as you see fit.

Read more about our API approach here, API-first.

📨 Webhooks

Webhooks allow you to get an automatic callback on given triggers: subscription expired, invoice settled, etc.

The Billwerk+ platform will automatically call a URL on your website whenever an event happens. If it is not successful in delivering the message, the delivery will be retried later.

If you use webhooks, you do not need to periodically poll our API to monitor for changes in customer and subscription behavior - these events are delivered to you automatically.
