Track Events

If present and equal to 1, Mixpanel will use the ip address of the incoming request and compute a distinct_id using a hash function if no distinct_id is provided. This is different from providing a properties.ip value in the Event Object.

If present and equal to 1, Mixpanel will respond with a JSON Object describing the success or failure of the tracking call. The returned object will have two keys: status, with the value 1 on success and 0 on failure, and error, with a string-valued error message if the request wasn't successful. This is useful for debugging during implementation.

If present and equal to 1, Mixpanel will serve a 1x1 transparent pixel image as a response to the request. This is useful for adding Pixel Tracking in places that javascript is not supported.

If present, Mixpanel will return a content-type: text/javascript with a body that calls a function by value provided. This is useful for creating local callbacks to a successful track call in JavaScript.
