Order shipment package/parcel dimension

Topic summary

  • Goal: Retrieve package/parcel dimensions for an order after delivery via the Fulfillment API, beyond already-accessible order and line items.

  • Current capability: Order and line items can be fetched. The requester’s app can call only the merchant’s Shopify store.

  • Key clarification: Package dimension properties are not available natively in Shopify’s APIs (including fulfillment/shipment data). There is no Shopify endpoint that returns delivered package dimensions.

  • Recommended approach: Obtain parcel details from the shipping carrier directly (referred to as “Carrier Service” here). This means making external API calls to carriers such as USPS, FedEx, etc., rather than relying on Shopify.

  • Outcome/status: Guidance provided; the solution is to integrate with carrier APIs to get package dimensions post-delivery. No further Shopify-side action or workaround was identified, and the thread effectively resolves with this direction.

Hi,

I am able to get Order and all line items using API endpoint. I also need to get package dimension for this order, after it has been delivered to the customer.

How can I get this data? Is there any API endpoint to get delivery/shipment/fulfillment data.

My app is only able to call merchant store. Do I need to make call to carrier on behalf of merchant and get the parcel details?

Thanks

Hey @iozyigit

These properties would not be available natively via Shopify’s API. It could be possible that you can get this information from the Carrier Service.

Thanks for the info, @Luke_K . You mean carrier service in the Shopify or just externally make api call to usps/fedex etc.

Hey @iozyigit

No worries! So, yes I meant externally making an API call in this case. Thanks!
