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 succesfull 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.
Check out our reference documentation for more information about webhooks.
