What is the BigCommerce + ShipperHQ integration

Shipping is where carts go to die. When rates feel off, delivery promises look vague, or checkout can’t reflect real packaging and carrier rules, shoppers hesitate, support tickets pile up, and margins get chipped away by undercharged shipping. The Bigcommerce ShipperHQ integration connects your store checkout to ShipperHQ rate logic, so shipping options, pricing, and delivery estimates can be calculated from the same rules your ops team uses day to day. It turns shipping from a static settings page into something you can model, test, and keep aligned with how you actually ship. This setup fits if your Bigcommerce store ships with multiple carriers, zones, methods, or product-based shipping rules that basic rate tables can’t cover.

How the BigCommerce ShipperHQ integration works technically

• Bigcommerce checkout requests shipping quotes and passes destination, cart contents, quantities, and cart value to ShipperHQ via API.

• Product attributes used for rating (weight, dimensions, origin, freight class, hazmat flags, and shipping groups) are mapped from Bigcommerce catalog fields to ShipperHQ rule inputs.

• Rate rules evaluate carriers, methods, packing logic, and surcharges in ShipperHQ, then return a normalized list of methods with prices and optional delivery estimates back to Bigcommerce.

• Address validation and method restrictions are applied during the quote response, with unsupported destinations and services filtered before display at checkout.

• Rate calls are handled per request, with timeouts and fallback behavior depending on checkout context, and errors captured in logs for troubleshooting.

• Selected shipping method codes are stored on the Bigcommerce order and can be mapped to downstream fulfillment, WMS, or carrier-label workflows.
