Delete Channel Subscription
This tool allows you to unsubscribe devices or clients from push notifications for specific channels. the operation is asynchronous, so immediate requests after deletion may briefly still return the subscription.
Why this helps
Retired work can continue generating notifications for devices or clients that no longer need them.
- Reduce stale notifications
- Keep delivery targets relevant
- Automate cleanup follow-up
