Record custom events from your server (shape-only: a name, a time, IDs and tags)
POST /api/v1/events · operationId recordCustomEvents
For developers: your server sends this request with a server key; it is not a button in the dashboard.
Counted per day, per account and month; never a message, parameters or payload: unknown fields are refused. A resent eventId is a replay. See Custom events, tags and debug mode.
Authentication
Send Authorization: Bearer YOUR_SERVER_KEY (siteServerKey: Site server key in Authorization: Bearer <key> (the scheme is case-insensitive and required; a bare key is 401). Shown once on creation or rotation. Publishable keys cannot authenticate). Keep the server key in server-only configuration; never send it to a browser.
