We have decoupled our Webhook subscription API from the notification feature to provide a better developer and maintenance experience. Currently, both the old and the new implementations are running in parallel. During this maintenance window, we will migrate the remaining subscriptions to the new implementation and turn off the old one.
We don't expect any interruption of services, however, for a short period of time, events that were subscribed to in the old implementation will be delivered twice. As consumers normally de-duplicate based on event IDs anyway, this should not pose an issue to them.
For additional details, please refer to the following announcements.
