ShipSaving New API (v2)
Request
This endpoint allows you to quickly retrieve shipment rate quotes by providing the from_address_data, to_address_data, package_data and the ship_date.
Each API call can include up to 10 individual rate requests.
Previously, this endpoint only returned rates for USPS Ground Advantage. With the new update, you may optionally specify additional carriers and service levels using the shipment_rate_carrier_data field. A detailed explanation of how to use this parameter can be found in the request schema.
If
shipment_rate_carrier_datais omitted: The system will return rates only for USPS Ground Advantage (default behavior).If
shipment_rate_carrier_datais provided: The system will return rates only for the specified provider(s) and service level(s). Multiple combinations may be sent in a single request.

Request
Creates and pays for a shipment label using the rate_id obtained from a prior get_rates call. This endpoint also allows purchasing shipment insurance in the same request (insurance cannot be purchased separately).
To prevent duplicate purchases caused by network fluctuations or retries, the API checks ether a shipment already exists under the specified platform_uk_id.
- If a related shipment is found, the existing shipment information will be returned, and the
duplicate_labelfield in the response will be set totrue. - If no shipment exists, a new shipment will be created as normal, and the
duplicate_labelfield will befalse.
Security
BearerAuth
The unique identifier of a shipping rate returned by the get_rates endpoint. Use this value to reference a specific rate when purchasing a label.
Example: "dc288147-f7dd-494d-9353-5ce00020c7aa"
A unique identifier provided by the calling party (e.g., the caller’s order number). Each platform_uk_id must correspond to exactly one shipment and cannot be reused across multiple shipments.
Example: "platformUkId175377917713"
Defines the label print format. Supported types vary by carrier and may also depend on the selected service level. For example, USPS and FedEx may support qrcode, while UPS may support barcode.
Enum"common""qrcode""barcode"
Example: "common"
