ajax: post array of products to create invoice, the products rows are random

I am working on an invoicing app, and how do I post products to the quote products table, by iteration as an array. As you may know the invoice has an indefinite number of products attached to it each time.

$http({
            method: 'POST',
            url: serverDomain + '/classes/fs_quote',
            data: {
                price:    $scope.price,
                name:      $scope.name,
                qty:   $scope.qty
            },
            headers: configParams
        }).then(function success(response) {
            console.log(response.data)
        }, function error(response) {
            console.log(response.data);
        });
