I was contacted and asked to consider changing (improving) or removing my 3 star rating. In the interests of transparency, I prefer to let it stand as-is for those who may get value from it.
Four different Shopify Support staff recommended that I install this app to provide improvements I was looking for with carrier calculated rates. This app does not provide any integration with carrier calculated rates. As Shippo noted this "...is simply not what Shippo was designed for."
Yet Shippo does claim that "With Shippo API, you can automate your entire shipping process easily and get rates and labels right on your website."
At best several points of this statement are marketing embellishment. In reality, rates are not on your website; neither front-end or back-end. Store owners are redirected to a Shippo URL. And automating your entire shipping process is another obvious overstatement of it's capabilities.
There are other shipping apps that do have APIs for integration of carrier rates available. it is possible, just not with Shippo.
