There is a signal sent for every webhook event. You can access them by doing the following:

from django.dispatch import receiver

from pinax.stripe.signals import WEBHOOK_SIGNALS

def handle_payment_succeeded(sender, event, **kwargs):
    pass  # do what it is you want to do here

If you make sure that is imported at startup then this code example above will execute the handle_payment_succeeded function everytime the invoice.payment_succeeded event is sent by Stripe and processed by your webhook endpoint.

The event object is a processed and verified Event model instance which gives you access to all the raw data of the event.
