Hello!
You can definitely customize shipping prices based on the dimensions you receive from your API. Here’s how you can approach it:
Use Shopify’s API: You can create a custom app that interacts with Shopify’s Shipping Rates API. This allows you to modify shipping rates dynamically based on the weight, width, height, and length.
Webhook Integration: Set up a webhook to catch shipping rate calculations. You can intercept the rates from your API and adjust them before they are sent to the cart.
Custom App Logic: Within your custom app, fetch the API data, calculate the shipping cost based on the provided dimensions, and return the modified rates to Shopify.

Hey @user198
This is David from PieLab here.
Yes, you absolutely can use Shopify’s Admin API on the Basic plan.
Here are the official API docs:

Thank you for replay. After searching for API i found /admin-rest/2025-07/resources/carrierservice#post-carrier-services but the catch is its not free for basic plan you can see in this attached file for reference.
Hi user198,
Thanks for your follow-up! You’re correct that some API functionalities, like the Carrier Service API, may incur additional fees even on the Basic plan. Shopify provides various features that can have different costs associated with them.
If you’re looking to use specific APIs, it’s a good idea to review Shopify’s pricing details and documentation to understand any limitations or additional charges.
If you have further questions or need clarification on any specific API functionality, feel free to ask!
Thank you for you support.
carrier service is really if you need realtime/dynamic rates in CHECKOUT.
Which is NOT the same as setting up shipping profiles and shipping rates through the api before hand.
There’s also shopify-functions for interacting with shipping checkout for different use cases.
Keep researching.
