Delete a subscription. DELETE /subscriptions/{subscriptionId}. Warning: Prefer changing status to archived (update_subscription_status) instead of deleting when you want to end a subscription without removing it from records.
AI agents call delete_subscription to permanently remove resources in Rebillia MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes subscription records, which cannot be undone. The warning in the description reinforces that deletion removes records entirely rather than just changing status. In a subscription billing system, deleting subscriptions has significant business consequences including loss of customer history and potential accounting issues.
