name: Sendlane Client-Side Components
description: >-
  Embeddable, client-side surfaces Sendlane ships for a merchant's own website —
  distinct from SDKs (there are none) and from the REST API. One family: the
  Sendlane Beacon tracking script.
component_count: 1
families:
  - name: Beacon
    kind: tracking-script
    description: >-
      Website and event tracking. Collects on-site customer activity — sign-ups,
      page and product views, add-to-cart, checkout started, purchases — and feeds
      the same event stream as the server-side /tracking/* endpoints, so
      automations can trigger on real-time browsing behaviour.
    loader: https://sendlane.com/scripts/pusher.js
    install: '<script src="https://sendlane.com/scripts/pusher.js" async data-token="INTEGRATION_TOKEN"></script>'
    auth: >-
      Public integration token, supplied via the data-token attribute. Obtained from
      the dashboard by selecting Manage next to the Sendlane Integration and copying
      the code. This is not the v2 API bearer token.
    registry: cdn
    version: null
    published: null
    version_note: >-
      The distribution is UNPINNED — the script tag names no version and the URL
      floats to latest. Probed 2026-08-13: HTTPS 200, application/javascript, 88,500
      bytes, a webpack bundle. There is no CDN metadata endpoint to query (it is
      served from Sendlane's own origin, not npm/unpkg/jsDelivr), so no release date
      is knowable. A merchant embedding this cannot tell what build they are running,
      and neither can we.
    constraints:
      - >-
        Only one instance of pusher.js may be installed on a site; multiple
        instances cause tracking issues (provider's own guidance).
      - Requires backend/theme access to install the tag.
    events_produced:
      - Active on Site
      - identify
      - product viewed
      - added to cart
      - checkout started
      - order placed
      - ordered product
      - order fulfilled / cancelled / refunded
    see: asyncapi/sendlane-webhooks.yml
absent:
  - web-components / custom elements
  - hosted or prebuilt UI element library (payment-element style)
  - embedded dashboards or analytics iframes
  - a documented forms/reviews embed API
notes:
  - >-
    Sendlane markets Forms and Reviews as products, and both necessarily render
    client-side, but neither publishes a documented embed contract, a loader URL or
    a configuration API. Only the Beacon loader is documented well enough to record.
