What is the Shopify + ShipperHQ integration

Are shipping rates, delivery options, and checkout promises the thing you keep revisiting before every campaign or peak? When rates live in spreadsheets, carrier portals, and apps, small rule changes turn into support tickets, cart abandonment, and “why did this customer get free shipping?” moments. The Shopify ShipperHQ integration connects your store checkout to ShipperHQ’s rating and rules engine, so Shopify can request real-time rates and options based on cart contents, destination, and delivery rules. The result is one place to manage shipping logic while customers see consistent choices at checkout, and orders carry the selected method through to fulfillment. This setup fits if your Shopify shipping needs go beyond flat rates, simple zones, or a single carrier.

How the Shopify ShipperHQ integration works technically

• During checkout, Shopify sends cart and destination details to ShipperHQ for live rate quoting via API.

• Products and cart lines are mapped to ShipperHQ attributes such as shipping groups, dimensions, weight, origin, and special handling flags.

• ShipperHQ applies rules for carriers, methods, surcharges, free shipping, and delivery options, and returns eligible methods and prices to Shopify.

• Returned methods are normalized to Shopify shipping rate formats, including method names, service codes, and taxability where applicable.

• The chosen shipping option is stored on the Shopify order and passed downstream to fulfillment flows for label purchase and packing logic.

• Address validation and rate request errors are handled as structured responses, with logged payloads for troubleshooting and rule tuning.
