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||50||2000|
|Authentication||Project Token, intended for untrusted clients.||Project Secret, intended for server-side integration.|
|Content-Type||application/x-www-form-urlencoded||application/json or application/x-ndjson|
|Ingesting historical events||Last 5 days only.||Any time after 1971-01-01.|
The limits for track are the same as /import, see here.
