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.

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.
