Back to the API reference

This reference may be out of date

This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-10-01 06:30 UTC.

API reference Shipping

Shipping rate quotes: quotes carrier rates for one lane.

POST /api/shipping/rate-quotes deprecated

Requires: Shipping.RateQuotes, merchant scope.

The quote runs through the merchant's own shipping provider binding. The request names a saved ship-from origin or supplies one inline, names saved parcel presets or supplies parcels inline, and gives the destination. The response carries the outcome and, on success, the rate options. A merchant with no enabled shipping provider receives the `NotConfigured` outcome rather than an error. Quotes are rate limited per merchant; a caller over the ceiling receives `Shipping:QuoteRateLimitExceeded` with HTTP 429.

Example request

Every block below sends the same request. Replace {{BASE_URL}} with the address of the API you are calling and {{API_KEY}} with your own key.

The request body is a ShippingRateQuoteRequestDto. See the Request body section below for its fields.

Parameters

Name In Type Description
suppressNulls required query boolean If true, omit properties with null values.

Request body

application/json , required

Field Type Description
merchantId required string (uuid) The merchant the quote is for. The caller must be authorized over this merchant; an API key quotes only for the merchant it belongs to. nullable
originId required string (uuid) The id of a saved ship-from origin belonging to the merchant. Give this or `origin`, not both. Conditional: When OriginId is not null. nullable
origin required all of Address A ship-from address supplied inline, for a quote from a location the merchant has not saved. Give this or `originId`, not both. Conditional: When Origin is not null.
destination required all of Address The address the parcels ship to.
destinationIsResidential required boolean Whether the destination is a residence. Some carriers price residential delivery differently; leave unset when unknown and the provider applies its own default. nullable
parcelPresetIds required array of string (uuid) The ids of saved parcel presets belonging to the merchant, one per parcel in the shipment. Give this or `parcels`, not both. nullable
parcels required array of ShippingRateQuoteParcelDto The parcels supplied inline, one per parcel in the shipment. Give this or `parcelPresetIds`, not both. nullable
carriers required array of string Optional provider-specific carrier account identifiers to restrict the quote to. When omitted the provider quotes every carrier the binding allows. nullable
serviceLevels required array of string Optional provider-specific service level tokens to restrict the quote to. When omitted the provider returns every service level the binding allows. nullable
currency required string The ISO 4217 currency the quotes should be expressed in. When omitted the platform's configured default currency is requested. Conditional: When Currency is not empty. nullable

Responses

200 OK

Body: ShippingRateQuoteResultDto Each item has these fields.

Field Type Description
outcome required all of ShippingRateOutcome What happened. `quotes` carries options only when this is `Success`.
isSuccess required boolean Whether `outcome` is `Success`. read only
providerName required string The name of the provider that answered. The platform's fallback provider answers when the merchant has no enabled binding, with the outcome `NotConfigured`. nullable
quoteId required string (uuid) The identifier the platform recorded this quote under, when the outcome is success. A checkout that lets a shopper choose a service sends this identifier and the chosen option's `optionId` back, never an amount: the server re-reads the recorded quote and charges the amount it stored. Absent for a non-success outcome. nullable
expiresAt required string (date-time) When the recorded quote stops being honored, in UTC. A selection submitted after this instant is refused and the lane has to be quoted again. Absent when `quoteId` is absent. nullable
quotes required array of ShippingRateQuoteDto The rate options, ordered as the provider returned them. Empty unless the outcome is success. nullable
messages required array of string Provider or platform messages explaining a non-success outcome. Never carries a credential, a URL or a raw exception. nullable

Field Type Description
error required RemoteServiceErrorInfo

This response has no documented body fields.

default The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. See the error-code reference in this document's description for the values `error.code` can take.

This response has no documented body fields.

429 The request was refused because a rate limit was exceeded. Wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling.

Body: RateLimitProblemDetails Each item has these fields.

Field Type Description
type required string The problem type identifier. Always the same value: the failure is the status code itself, so there is no sub-type for a caller to branch on. nullable
title required string A short, human-readable summary of the problem type. nullable
status required integer (int32) The HTTP status code, repeated in the body as the problem-details format defines.
detail required string A human-readable explanation of this occurrence of the problem. nullable
retryAfterSeconds required integer (int32) How long to wait before retrying, in whole seconds, carrying the same figure as the `Retry-After` header. Always at least one: a value of zero would invite an immediate retry that is certain to be rejected again.
