I’m using add_to_cart method to add a variation to cart with Ajax, this works but I can’t find a way to add multiple variations using the same request.

If I send one_data it works, but not with multi_data

product_id in this code works if the product is variable, so it’s the variation id.

Code:

jQuery(function($) {
    $(document.body).on('click', '#button', function(e) {
        //const one_data = { product_id: 592, quantity: 1 }
        const multi_data = [
            { product_id: 592, quantity: 2 },
            { product_id: 593, quantity: 1 },
            { product_id: 594, quantity: 3 }
        ];

        $.ajax({
            type: 'POST',
            url: wc_add_to_cart_params.wc_ajax_url.toString().replace( '%%endpoint%%', 'add_to_cart' ),
            data: multi_data,
            success: function(res) {
                console.log(res);
            },
        });
    });
});
