Hi,

Once you install a shipping plugin on your Joomla website, you need to go in the menu System>Shipping methods of HikaShop, click on the "new" button, select your shipping plugin and configure a shipping method for it.
Once done, you'll see the shipping method you created selectable in this option.
Did you do all this first ?

yes we did it but when do the restriction at payment method the shipping created is not showing

Hi,

For the "shipping methods" option in the payment methods and custom order fields, you need to implement the shippingMethods method in your shipping plugin class.
For example, in the Australia Post v2 plugin we have:

yes the options is showing now at the restrictions, but it not showing at payment page since it cannot capture the shipping options, do you have any suggestions for this?

Hi,

Well, for the checkout, you need to implement the onShippingDisplay(&$order,&$dbrates,&$usable_rates,&$messages) method in your plugin and have it request the available shipping services / costs for the shipping address of the user and then duplicate the shipping method object of the shipping plugin from the $dbrates array to the $usable_rates array (one per service / cost you want to offer).
