Not every tool has a direct integration. With Zapier's Webhooks by Zapier action (POST, payload type JSON) you can send BrainyMetrics anything your other apps know about: a new CRM lead, an invoice paid in your accounting tool, a call logged by your sales team.
Set type to lead, order, refund, appointment or call; the other fields match the server API. No API key is needed because the URL is the credential. Send an array to record up to 100 items at once, and include visitor_id (the tracko_vid value) for an exact browser match.
