- 2Create an automation in Automations, New Automation, or tell Notis from any channel.
- 3In one instruction, ask Notis to list available ClickHouse databases and summarize them for cancellation follow-up.
- 4Pick Event Canceled or Deleted as the trigger and choose where run reports should go.
- 5Test with one real cancellation and review the inventory.
