Update inbox or pod subscriptions, or replace the webhook’s event_types in full when you pass a
non-empty event_types array (see request field docs). Inbox and pod changes use add/remove lists.
CLI:
Bearer authentication of the form Bearer <token>, where token is your auth token.
When you send a non-empty list, it replaces the webhook’s subscribed event types in full (the same
“set the list” behavior as create). It is not a merge or diff: include every event type you want after
the update. Sending a one-element array means the webhook will only receive that one type afterward.
Omit this field or send an empty array to leave event types unchanged. Clearing all types with an empty
list is not supported. Subscribing to message.received.spam, message.received.blocked, or
message.received.unauthenticated requires the matching label permission on the API key.
