  description: Hosted employer onboarding flow embedded in the partner's product
    as an iframe. The partner creates a secure session via POST /employer_onboarding_sessions,
    embeds the returned claim_url as the iframe src, and handles the THATCH_REDIRECT
    postMessage event (origin https://app.thatch.com) to redirect the employer when
    they finalize allowances. Thatch handles all onboarding logic and data collection
    inside the iframe (account creation, bank connection, employee invites).
  components:
  - name: thatch-employer-onboarding
    element: iframe
    src: claim_url returned by postEmployerOnboardingSessions
    events:
    - type: THATCH_REDIRECT
      payload: redirectUrl
      origin: https://app.thatch.com
notes: Thatch for Platforms is marketed as "APIs and embeddable components". The
  employer onboarding iframe is the embeddable component documented publicly; no
  standalone JS component/loader library is published (npm scope carries design-system
  tooling only).
