Environment / auth
  • HANDSET_API_KEY
    required
    secret

    Handset API key. Use a test-mode key (hs_test_…) — simulated carrier, free. Live keys are refused unless HANDSET_ALLOW_LIVE=1.

  • HANDSET_ALLOW_LIVE

    Set to 1 to permit a live-mode key (the agent can then text and call real people at real cost).
