Delete contact person by reference using ContactPerson/delete (doc 1.27). Nova Poshta allows deletions via API only for legal entities and only until the contact was used on an Internet document.
AI agents call contact_person_delete to permanently remove resources in Novaposhta — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes contact person data from the Nova Poshta system. Although deletions are restricted to certain conditions (legal entities, pre-document-usage), the operation itself is destructive and cannot be undone. An AI agent misusing this could permanently remove critical contact records, disrupting business operations and customer relationships.
From the tool's definition Tool name explicitly contains 'delete'. Description states it performs deletion via API and references 'ContactPerson/delete' endpoint.
