How to integrate PostNL shipping?

There is no plugin to automatically retrieve the rates based on the products in the cart and the address of the customer.
However, you can potentially enter the different rates in hikaShop by creating manual shipping methods with each one having a price and the correponding restrictions for weight/volume/zone etc.

You can potentially ask them but I doubt that they do it. They will probably direct you to a third party developer for that.
Also, it might not be possible if they don't have an API for that (not all the shipping methods have one).

If they have an API or that and that they have a PHP developer, that should be doable in a few days of work for him maximum, maybe less.

Hi,

On my end, I didn't see any progress for such plugin. But as I said, any PHP developer should be able to do that.
