The updates to File integration apply to both JSON and XML files.

Effective Date: January 15, 2026

On January 15, 2026, we're releasing an update to Shipmondo's Shopify app that introduces a new format for shipping method codes. This change enables advanced shipping configurations for webshops while providing partners with better access to shipping method details via our API.

What's changing?​

New shipping method code format​

The Shipmondo app stores delivery information in the code field of shipping_lines in Shopify orders. We're transitioning from the existing format to a new, more flexible format.

Current format:

dk_gls_service_point_95433
dk_dao_service_point_1250
dk_dao_private

New format:

SHIPMONDO;{method_id};{pickup_point_id}

Example:

SHIPMONDO;12345;95433

Where:

• SHIPMONDO = prefix for unique identification of the source
• method_id = unique ID for a shipping method created in the Shipmondo app (e.g., 12345)
• pickup_point_id = ID for the pickup/service point (optional, depends on the shipping method, e.g., 95433)

In a greater effort to improve customs in Shipmondo, a number of fields have been introduced to shipments:

• parties array
• pickup_details object
• delivery_details object
• service_point_id string
• customs > freight_cost float
• customs > insurance_cost float

At the same time a number of fields have been deprecated:

• sender object
• receiver object
• pick_up object
• bill_to object
• service_point object
• return_to object
• customs > billed_to_custom_invoice_text string
• customs > sender_custom_invoice_text string
• customs > receiver_custom_invoice_text string

There are no current plan to remove these fields, but it is recommended to stop using them from now on, as new features will only be added to parties.

Guides​

Check out the new guide for parties for further details of the structure of parties.

Also check out the new guide for migration to parties from the deprecated address objects.

Also check out the updated API reference for reference of the structure of each new field.

We have introduced an endpoint which allows you to delete sales order.
