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

The Carrier Service API is required when using Zapiet - Rates by Distance, in order to show the rates in the checkout.

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

Add the Carrier Service API feature

Requirements

  • You need to be logged into the store owner account to manage 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. In Shopify settings, click Plan section, then click Change Plan.

  2. Click Choose this plan button under the Shopify plan.

  3. Select the billing cycle and confirm it. Then, select payment method and click Subscribe.

  4. 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?”


Pay monthly

  1. Visit the Shopify help center and log into your account.

  2. Select Account.

  3. Select Plans and billing.

  4. Scroll down and select Chat with us.

  5. Copy and paste the text below into the Your message field and click Chat with us.


    "Could you add the Carrier Service API to my plan for $20/month so that I can use Zapiet's rates features?"


Troubleshooting

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—only Shopify can make changes to the Carrier Service API feature.
