woocommerce_rest_missing_nonce

Hello there,
I just update the plugin and trying to add-item to the cart via postman:
POST https://enbeta.arvandkala.org/wp-json/wc/store/cart/add-item?product_id=407053&quantity=1

and I get the following error:

{
    "code": "woocommerce_rest_missing_nonce",
    "message": "Missing the X-WC-Store-API-Nonce header. This endpoint requires a valid nonce.",
    "data": {
        "status": 401
    }
}

Could you help me, please.
thanks much
