Add Volume to shipping

Hi everyone,
I need to add a custom Volume/Weight shipping cost algorithm on my shop; can anyone give me some hint or some examples on where to work on?
I’m a fairly skilled web programmer, so language or logic is not a problem, but I’m totally new to Wix or Corvid so I don’t know where to phisically start working on adding the shipping logic or the new custom “Volume” field on products.

Thank You to anyone who can help!

Hi,
You can add custom code using Corvid by Wix into the code panel .

Note that Wix has build-in shipping options. Click here to learn more.

You can also find wix-stores API useful.

Thank You very much for all the resources!

Is there a way to add a new input field in the store’s “new product” backend page?
Or the only way to add custom fields to a product is by populating manually the custom collection?
