The API reference isn't available right now

This instance couldn't load its API specification. The reference returns as soon as the specification is readable again.

Back to the API reference

No such model

This instance publishes no model under that name. It may have been renamed, or no operation this installation serves uses it.

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This reference may be out of date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 2026-10-22 22:52 UTC.

API reference Models

ShippingRateOutcome

A model the API reference uses in a request or a response. The operation pages link every field typed as this model here.

How a rate request ended, so a caller can tell "no rates for this lane" from "provider unreachable" from "misconfigured" from "not configured". Failure is never modelled as an empty quote list.

Values

Values: Values combine: send one or more member names separated by a comma and a space, or the integer sum of their values. Responses carry the names.
Success The provider answered with at least one quote.
NoRatesForLane The provider answered, and no carrier it reaches serves this origin, destination and parcel combination. Not an error: the page shows no options and the merchant checks the lane.
NotConfigured No provider is configured or enabled. The null provider's only answer.
Misconfigured A provider is configured but its own settings are incomplete or invalid (a missing credential, an unusable carrier account filter). An administrator fixes this on the settings page.
AuthenticationFailed The provider rejected the credential (HTTP 401 or 403).
RateLimited The provider throttled the caller (HTTP 429).
InvalidRequest The provider rejected the request as malformed or unsupported (any other 4xx).
ProviderUnavailable The provider could not be reached or answered with a server-side fault: a transport failure, an open circuit, or a 5xx.
Timeout The call did not complete within QuoteTimeoutSeconds.
MalformedResponse The provider answered 2xx with a body the response mapper could not read.
