Starting in 10.03.00 there are new helper functions available in runtime.js that allow you to do things like update items in the basket or calculate and apply shipping to a basket. The underlying functions are available in the JSON API here under runtime: https://docs.miva.com/json-api/
These helper funcitons make it easier to run these runtime functions to manulipate the cart and perform other funcitons.
All these functions had a optional delegator parameter which the Miva admin uses to group and priortize requests. It can be omitted in most cases unless your features need that type of grouping and priortization.
