  portals. Versions and dates read from each registry's metadata endpoint on 2026-08-27.
note: >-
  Lightspeed publishes no first-party REST client library for its four flagship APIs (Retail X-Series,
  Retail R-Series, eCom C-Series, Restaurant K-Series). The @lightspeed npm scope is real and
  first-party, but it carries payments, storefront-headless, CLI and design-system packages rather
  than API clients. The most-used Retail SDKs on npm and Packagist are community-maintained and one of
  them says "unofficial" in its own description. This is the single largest developer-experience gap
  in the profile.
packages:
- name: '@lightspeed/online-payments-sdk'
  registry: npm
  url: https://www.npmjs.com/package/@lightspeed/online-payments-sdk
  language: JavaScript
  official: true
  version: 1.7.3
  published: '2026-08-25'
  covers: Lightspeed Payments (online payments drop-in / components)
  note: >-
    First-party, on the company-controlled @lightspeed npm scope, and the most actively maintained
    Lightspeed package in any registry. Wraps the payments surface, not the Retail/Restaurant REST APIs.
- name: '@lightspeed/ecom-headless'
  registry: npm
  url: https://www.npmjs.com/package/@lightspeed/ecom-headless
  language: JavaScript
  official: true
  version: 1.1.4
  published: '2026-05-21'
  covers: Lightspeed eCom E-Series (Ecwid) public API
  note: >-
    Description reads "Headless JS client for Ecwid public API" — the closest thing Lightspeed ships to
    a first-party API client, and it targets the E-Series (Ecwid) product only.

  url: https://www.npmjs.com/package/@lightspeed/crane
  language: JavaScript
  official: true
  version: 3.6.1

  repository: https://github.com/Ecwid/ecwid-js-sdk
  covers: Lightspeed eCom E-Series (Ecwid) storefront/API JavaScript SDK
  note: >-
    Published by the Ecwid GitHub organization, which Lightspeed acquired in 2021 and sells as eCom
    E-Series. Last release 2023-11-09 — nearly three years stale as of this pass.
- name: lightspeed_restaurant
  registry: rubygems
  url: https://rubygems.org/gems/lightspeed_restaurant
  language: Ruby
  official: true
  version: 3.5.0
  published: '2024-12-10'
  repository: https://github.com/chronogolf/lightspeed_restaurant
  covers: Lightspeed Restaurant (K-Series) API
  note: >-
    Published from the Chronogolf GitHub organization — Chronogolf is the Lightspeed Golf business
    Lightspeed acquired in 2019, so this is an internal Lightspeed team's gem rather than a community
    one. Not linked from any Lightspeed developer portal.
- name: lightspeed-retail-sdk
  registry: npm
  url: https://www.npmjs.com/package/lightspeed-retail-sdk
  language: JavaScript

  published: '2026-01-18'
  repository: https://github.com/darrylmorley/lightspeed-retail-sdk
  covers: Lightspeed Retail R-Series API

- name: anytech/lightspeed-x-series-api
  registry: packagist
  url: https://packagist.org/packages/anytech/lightspeed-x-series-api
  language: PHP
  official: false
  version: null
  published: null
  repository: https://github.com/anytech/lightspeed-x-series-api
  covers: Lightspeed Retail X-Series API (OAuth client)
  note: >-
    Community package. Version/date not recorded — Packagist search returns no version field and the
    per-package metadata endpoint was not probed in this pass; an honest gap rather than a guess.

  registry: packagist
  url: https://packagist.org/packages/seoshop/seoshop-php
  language: PHP
  official: false
  version: null

  note: Version/date not recorded — same gap as above.
