Our latest rates feature allows merchants to use Zapiet - Pickup + Delivery rates without needing access to Shopify Carrier Service API. Take a look at our Zapiet - Pickup + Delivery rates article for more details.

Only proceed with this article if, because of the limitations of our newest rates feature, you need to use our rates with the Carrier Service API.

The Carrier Service API (also called the Carrier-calculated shipping) is a Shopify feature that allows apps like Zapiet - Pickup + Delivery to generate rates within your checkout. You can learn more about it in the Shopify Carrier-calculated shipping article.

Availability of the Carrier Service API feature depends on the Shopify plan you are on.

Why do I need the Carrier service API?

The Carrier Service API is required if you want to show the customer only the rates that are related to the checkout method selected in the widget.

  • When Store Pickup is selected, only show the store pickup rate

  • When Local Delivery is selected, only show local delivery rates

  • When Shipping is selected, only show shipping rates

If your rates are added to your Shopify shipping zone, all rates will appear at the same time regardless of checkout method selected.

  • You need to be logged into the store owner account to mange billing changes

  • You need to be on the Shopify plan called Shopify

    • Carrier Service API is not available on Starter and Basic plans

You can add the Carrier Service API to your Shopify plan in two ways:

    • You can pay Shopify $20 per month for the Carrier Service API feature.

Zapiet does not benefit in any way from charges for the Carrier Service API. This is purely a Shopify feature.

Switch to annual billing

  1. Within Shopify settings, click Plan.

  2. Click Change plan.

  3. Select Yearly, and click Choose this plan button under the Shopify plan.

  4. Select the billing cycle, confirm it and click Start plan.

  5. Once you have switched to annual billing, contact Shopify through the Shopify Help Center and ask:

    "I have just switched to annual billing in order to use the Carrier Service API for free. Could you enable it on my account as soon as possible so that I can use Zapiet's rates features?"

If the Carrier Service API is not active on your Shopify plan, you'll see the following message in Shopify Settings > Shipping and delivery > Carrier accounts. You'll need to contact Shopify Support to enable it.

The Carrier Service API can be automatically disabled in some circumstances, for example:

  • Your Shopify plan was downgraded

  • Your billing cycle frequency was changed from annual to monthly

  • Your annual plan came to an end

  • Your store was moved from a Development plan to a paid plan

In these cases please contact Shopify Support to re-enable the Carrier Service API.

Please note that Zapiet is not able to enable or disable the Carrier Service API on your Shopify plan.

Next step

Once you have enabled the Carrier Service API, follow our Rates setup guide to set up your pickup, delivery and shipping rates.
