As an e-commerce merchant, I want to display real-time, dynamically calculated shipping rates from my connected carriers directly during the checkout process.

Currently, merchants must rely on static or flat-rate shipping rules, which can lead to undercharging or overcharging customers, especially for heavier or international packages. We request that the Delivery Gateway app automatically fetches live rates via carrier APIs based on the cart's total weight, dimensions, and the selected destination or pickup point.
