Sendle

Sendle is a parcel delivery service built for small businesses, best known for 100%-carbon-neutral door-to-door shipping in Australia, the United States and Canada. The original operator, Sendle Pty Ltd, ceased trading in January 2026 and entered liquidation, and its API host, developer hub, sandbox and status page were withdrawn from DNS. In July 2026 McKenna Worldwide Services, an Australian logistics company with Quantium Solutions heritage, bought the Sendle brand, domain names and trademarks from the liquidators (not the company or its debts) and relaunched it, debuting the new Sendle at Online Retailer in Sydney on 22-23 July with operations expected by September 2026; Quantium Solutions handles the deliveries behind the customer-facing brand. As of 3 October 2026 www.sendle.com answers again, but api.sendle.com and developers.sendle.com still do not resolve, so no API from the relaunched Sendle has been confirmed. The five OpenAPI definitions in this repository describe the original operator's API (quoting, orders, labels, tracking, USPS SCAN-Form manifests and tracking webhooks over HTTP Basic Authentication) and are kept as the record of that contract.

Sendle publishes 5 API contracts indexed on the APIs.io network, including Orders API, Products & Quoting API, Tracking API, and 2 more. Tagged areas include Shipping, Logistics, Last Mile Delivery, Parcel, 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.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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.
