How to add custom shipment CS-Cart - cs-cart

Question

I need to add dynamic shipment option to the checkout page, the shipment's pricing, duration and name come from other API.
I tried these hook, none of these invoked during checkout.
'get_available_shippings',
'get_shipping_methods',
'get_shipping_methods_post',
'get_shipments_info_post'
tried to hook shipping_methods_list.pre.tpl
{assign var="s" value=$all_shippings[0][1]}
{$s["shipping_id"] = '2'}
{$all_shippings[0][2] = $s}
I'm using cs-cart 4.14

The right hook was shippings_get_shippings_list_post, since it's not adding to the database, it seems you need to hook orders:shipping_info on the backend for further customization.
function fn_example_addons_shippings_get_shippings_list_post(&$group, &$lang, &$area, &$shippings_info)
{
$package_info = $group['package_info'];
$fromZipcode = $package_info['origination']['zipcode'];
$toZipcode = $package_info['location']['zipcode'];
$weight = (int)round(ceil($package_info["W"]));
$item_price = (int)round(ceil($package_info["C"]));
$shipments = fn_example_addons_getRates($fromZipcode, $toZipcode, $weight, $item_price);
foreach ($shipments as $key => $shipment) {
$shippings_info[$key] = $shipment;
}
}
for the shipments
$shipments["SHIPMENT_ID"] = array(
"shipping_id" => "SHIPMENT_ID",
"shipping" => "Example Shipment"
"delivery_time" => "2-3 days",
"description" => "",
"rate_calculation" => "M",
"service_params" => array(),
"destination" => "I",
"min_weight" => "0.0",
"max_weight" => "0.0",
"service_id" => "0",
"free_shipping" => "N",
"module" => null,
"service_code" => null,
"is_address_required" => "Y",
"rate_info" => array(
"rate_id" => "0",
"shipping_id" => "0",
"rate_value" => array(
"C" => array(
array(
"range_from_value" => 0,
"range_to_value" => "",
"value" => $price_in_point
)
)
),
"destination_id" => "1",
"base_rate" => "0.0"
),
"disable_payments_ids" => array()
);
