When one of your customers goes through the checkout flow, BigCommerce will reach out to ShipperHQ via an API call and ask ShipperHQ what shipping rates to offer to your customers. ShipperHQ will return a set of values in the API response and BigCommerce will use those values to display them to your customers.
As a part of the API request to ShipperHQ, BigCommerce will include basic information about the order that ShipperHQ needs in order to determine what shipping rate to offer your customer. The information we send includes product information such as:
- weight
- dimensions
- quantity
- price
- customer group (if any)
- free shipping (on or off)
- fixed shipping price (if assigned)
You can then set up shipping rules in ShipperHQ that offer specific shipping options to your customers, based on this data. Note that since ShipperHQ is controlling your shipping settings, shipping related discounts created within BigCommerce (coupons and Automatic Promotions) will not apply to the shipping options ShipperHQ presents during checkout.
