Documentation releases and API contract changes.

2026-10-04 · Public documentation

ParcelXpert Developers documentation is prepared for its official domain with page URLs, searchable API reference and OpenAPI download. This publishes documentation only; hosted test and live REST API access remain unavailable.

2026-10-04 · 1.0.0-preview.2 · unreleased hardening

Server-managed staff authority, label ownership and SSRF controls; persistent API keys, idempotency, rate counters and signed outbox architecture; current PX quote/booking/label/tracking adapters and API investigation metadata. Hosted test, live billing, international booking, cancellation, collection mutations, order booking and webhook self-service remain disabled.

2026-10-04 · 1.0.0-preview.1

Initial OpenAPI 3.1.1 contract, developer site, isolated local fixture sandbox, key lifecycle, scopes, durable idempotency, cursor pagination and signed webhook simulation. No live API release or production shipping changes.

Versioning policy

REST API v1 is the intended major contract. Preview schemas may change before launch and will be recorded here. After a stable release, breaking request/response changes need a new major version, migration guide and announced overlap. Additive optional fields and event types must be handled tolerantly by clients. Actual deprecation dates will be published when approved; no date is invented here.
