Track events to Mixpanel from client devices. We recommend using one of our client-side SDKs instead of using /track directly, as our SDKs provide queueing, retrying, batching, and more.
Typically, we recommend using /import for server-side integrations as it is more scalable and supports ingesting historical data. We only recommend /track for client-side tracking in an environment for which we don't have SDK support or if you're sending data via some other untrusted environment (eg: third-party webhooks that send data to Mixpanel).
Events per request

The limits for track are the same as /import, see here.
