Cold Chain - New API Field

:new_button: What’s new?

We’ve introduced a new optional field within the delivery_options object — cold_chain to support temperature-controlled deliveries.
This field allows clients to specify whether a package requires chilled or frozen conditions during transport.

:light_bulb: How does it work?

You can include the cold_chain field in your job creation request under the delivery_options section:

"delivery_options": {
  "cold_chain": "chilled"
}

Accepted values:

  • "chilled" – for refrigerated products.
  • "frozen" – for frozen products.

When this field is used, Stuart flags the order as temperature-controlled and applies the relevant delivery time limits.

For more detailed examples of request payloads and responses, please refer to our API Documentation.

:sparkles: What’s the impact?

  • Enables improved visibility and tracking of temperature-sensitive orders.
  • Supports compliance with “Collection to Delivery” (C2D) time requirements — ensuring that cold chain packages are delivered within the maximum allowed time between pickup and drop-off.
  • The C2D limit can be configured individually for each client; in such cases, it is necessary to align with the Stuart commercial team.
  • No breaking changes — existing API integrations will continue to work as before.

:date: When will this change take place?

The change is already implemented.
