Integrating Boxify rates

Boxify calculates the box size and count in each order, providing customers with accurate real-time shipping rates from UPS, FedEx, USPS, Canada Post and DHL Express.

If you would like Boxify rates to show only when your customers select delivery or shipping in our widget, we recommend integrating Boxify in the Rates tab of Store Pickup + Delivery app.


  • In order to use third party app's rates, Shopify requires you to have Carrier service API enabled. Read more in our Carrier service API article.
  • You need to have the Boxify app installed on your Shopify store and an active subscription with Boxify.

Disable Store Pickup + Delivery shipping rates

If you are using Boxify shipping rates only, we recommend removing any shipping zones in Store Pickup + Delivery shipping section. 

Only Boxify should be added as a carrier within Store Pickup + Delivery.

  1. Within Store Pickup + Delivery, open the Rates tab.
  2. Within the Shipping section, click Edit next to your shipping zone.
  3. Click Delete zone.
  4. Confirm to delete this shipping zone.

Your Store Pickup + Delivery shipping rates are now deleted, and the only rates generating for shipping will be coming from Boxify.

Prevent duplicate rates

When your Boxify rates are generating through Store Pickup + Delivery, we recommend removing Boxify as the carrier from Shopify shipping and delivery settings.

  1. Go to Shopify Settings and then Shipping and delivery.
  2. Under General shipping rates, Click Manage.
  3. Delete Boxify as a carrier if it's added in your domestic shipping zone.  

Only Store Pickup + Delivery should be added as a carrier under your domestic shipping zone. This way, our app can control which rates to show at checkout, depending on the checkout method selected in our widget.

If you are using Store Pickup + Delivery in multiple shipping profiles/zones, make sure to repeat the steps above to remove Boxify there as well. 

If you have international shipping zones where you need to use only shipping rates, add Boxify there directly. 

Store Pickup + Delivery should only be added as a carrier in your domestic shipping zone—take a look at our Rates setup guide for more information.
