Sendle

RETIRED — Sendle ceased operations on 11 January 2026 and the company entered liquidation; the API host, developer hub, sandbox and status page have all been withdrawn from DNS and returned NXDOMAIN when probed on 26 August 2026. Sendle was a 100%-carbon-neutral parcel shipping service built for small businesses, offering door-to-door delivery in Australia, the United States and Canada plus international shipping from AU and US to ~180 countries. Its API exposed quoting, order creation, label retrieval, tracking, USPS SCAN-Form shipping manifests and per-parcel tracking webhooks over HTTP Basic Authentication, with an Idempotency-Key header on order creation. The five OpenAPI definitions in this repository are retained as an archival record of a contract that can no longer be called.

Sendle publishes 5 APIs on the APIs.io network, including Orders API, Products & Quoting API, Tracking API, and 2 more. Tagged areas include Shipping, Logistics, Last Mile, Parcels, and E-Commerce.

The Sendle catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 2 Spectral governance rulesets.

Sendle’s developer surface includes authentication, GitHub presence, support, and 18 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/sendle: open an issue to ask a question, or submit a pull request to add artifacts.
