# Sendle

> RETIRED — DO NOT INTEGRATE. Sendle was a 100%-carbon-neutral parcel delivery
> service for small businesses in Australia, the United States and Canada, with
> international shipping from AU and US. Sendle cancelled all deliveries on
> 2026-01-11 and the company entered liquidation. As of 2026-08-26 the API host
> (api.sendle.com), the developer hub (developers.sendle.com), the sandbox
> (sandbox.sendle.com) and the status page (status.sendle.com) all return
> NXDOMAIN. The contracts below are an archival record of an API that can no
> longer be called.

Provenance: generated 2026-08-26 by the API Evangelist enrichment pipeline from
apis.yml and the artifacts in this repository. Sendle never published an
llms.txt of its own that is reachable today — developers.sendle.com/llms.txt
returned NXDOMAIN when probed on 2026-08-26.

## Status

- Company state: liquidation; operations ceased 2026-01-11
- API state: retired, host withdrawn from DNS
- Corporate website: https://www.sendle.com (HTTP 200, client-rendered shell)
- Lifecycle record: lifecycle/sendle-lifecycle.yml

## What the API was

Base URL: https://api.sendle.com/api (no longer resolves)
Authentication: HTTP Basic — account ID as username, API key as password
Idempotency: Idempotency-Key request header on POST /orders
Errors: custom JSON envelope {error, error_description, messages} — not RFC 9457
Rate limits: 10 requests/second per IP on parcel tracking; no rate-limit headers

## Contracts (archived in this repository)

- [Orders API](openapi/sendle-orders-api-openapi.yml): create, view, cancel and
  return parcel orders — createOrder, viewOrder, cancelOrder, returnOrder,
  viewReturnOrder.
- [Products & Quoting API](openapi/sendle-products-api-openapi.yml): one quote per
  shipping product for a route — getProducts, postProducts, and the deprecated
  getQuote.
- [Tracking API](openapi/sendle-tracking-api-openapi.yml): parcel scan history and
  per-parcel webhook subscriptions — trackParcel, subscribeToTrackingEvents,
  unsubscribeFromTrackingEvents.
- [Shipping Manifests API](openapi/sendle-manifests-api-openapi.yml): USPS SCAN
  Form manifests for US-domestic pickups — createShippingManifest,
  getShippingManifests, downloadShippingManifest, getShippingManifestOrders,
  getShippingManifestStatus.
- [Utility API](openapi/sendle-utility-api-openapi.yml): ping, for verifying
  credentials and idempotency-key handling.
- [Tracking AsyncAPI](asyncapi/sendle-tracking-asyncapi.yml): the tracking webhook
  event surface.

## Semantics

- [Conventions and reversibility](conventions/sendle-conventions.yml): auth style,
  idempotency, the absence of pagination, error envelope shape, rate-limit
  signalling, and which write operations could be taken back.
- [Error catalog](errors/sendle-problem-types.yml): every declared 4xx and what the
  three distinct 422 meanings were.
- [Data model](data-model/sendle-data-model.yml): Order as the single root
  aggregate, and the string join between an order and its tracking record.
- [Authentication](authentication/sendle-authentication.yml)
- [Rate limits](rate-limits/sendle-rate-limits.yml)
- [Plans and pricing](plans/sendle-plans-pricing.yml)
- [Sandbox](sandbox/sendle-sandbox.yml): a separate host, now also gone.
- [Standards conformance](conformance/sendle-conformance.yml)

## Agent surfaces

- MCP server: none. Sendle never shipped one. A derived candidate tool list is at
  mcp/sendle-mcp.yml with deployment mode `none`. A third-party npm package
  (@unclick/sendle-mcp) exists but is not a Sendle product and was first published
  after the API went dark.
- A2A Agent Card: none served. Every /.well-known/ path on every Sendle host is
  either a DNS failure or an HTML shell — see well-known/sendle-well-known.yml.
- Client libraries: no first-party SDK in any registry. Six community packages are
  catalogued in packages/sendle-packages.yml; all now wrap a host that does not
  resolve.

## Optional

- [GitHub organization](https://github.com/sendle): 38 public repositories, all
  forks of community libraries and hiring exercises. No API client.
- [Postman workspace](https://www.postman.com/kinlaneapi/sendle/overview):
  API Evangelist's collections, not Sendle's.
