We have implemented a Paypal susbcription into our SaaS project.

The subscriptions are working fine and now we want to integrate webhooks to automatically work with cancellations / non payment.

We struggle to find any information on how to work with webhooks inside a javascript environment.

The only source we find is this: https://developer.paypal.com/api/rest/webhooks/

Does anybody know about this or can give further advice?
