Custom checkouts, internal CRMs and offline sales need a way in. BrainyMetrics' server API accepts orders, refunds, leads, calls, call outcomes, appointments and ad spend, authenticated with a secret key.
Pass visitor_id (the tracko_vid value from a hidden field) for an exact browser match, or let BrainyMetrics match by email and phone. Read endpoints return attribution for an order, a lead's journey, and attribution reports, and read-only keys can only call GET endpoints.
