New webhook for failed payments

We have updated the webhooks events catalog to include the payment.failed event. When your Create a payment (with POST /v3/payments) or Create a bulk payment (with POST /v3/payments/bulk) request fails, BILL sends you a notification with information to identify your payment request and with error messages to help you debug.

You can now set up subscriptions to receive notifications for the new event.

See Payment notification payloads for more information.
