Delete a client recurring token by ID.

If you create the Purchase with the respective Client's ID (in .client_id), he won't see this token as available on checkout page anymore.

You also won't be able to use the ID of this object as a recurring_token in POST /purchases/{id}/charge/. The respective Purchase will have is_recurring_token set to false (as if POST /purchases/{recurring_token}/delete_recurring_token/ was issued).
