Delete a webhook by its ID.
AI agents call delete_webhook to permanently remove resources in Discord — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a webhook is a destructive action that cannot be undone. Webhooks are often used for critical integrations and automations; their removal would break those integrations. While not as severe as deleting all channels or messages, webhook deletion is irreversible and would require manual recreation and reconfiguration.
From the tool's definition Tool name is 'delete_webhook' with description 'Delete a webhook by its ID.' The verb 'delete' explicitly indicates irreversible removal of a resource.
