Delete a webhook subscription.
AI agents call delete_webhook_subscription to permanently remove resources in Filevine — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a webhook subscription, which cannot be undone without manual re-creation. Deletion of system integrations could disrupt event notifications, break dependent workflows, or cause monitoring failures if an AI agent mistakenly removes critical webhooks. This qualifies as Destructive rather than Write because the action is irreversible.
From the tool's definition Tool name is 'delete_webhook_subscription' and description states 'Delete a webhook subscription.' The verb 'delete' and explicit removal of a subscription represent irreversible data deletion.
