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.
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.
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.
When will this change take place?
The change is already implemented.
