Works just like "$set", except it will not overwrite existing property values. This is useful for properties like "First login date".

Query Params
integer
0 to 1
Defaults to 0

If present and equal to 0, Mixpanel will not perform geolocation parsing using the IP address of the request. We recommend setting the ip to "0" when making requests from the server-side to prevent the unintentional effect of overwriting your profile's geolocation with your server location. Defaults to 1 which would use the IP address of the request to update profile geolocation.

integer
0 to 1

If present and equal to 1, Mixpanel will validate the provided records and return a JSON object with per-record error messages for records that fail validation.

integer
0 to 1

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.

string

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.

Body Params
string

Defaults to YOUR_PROJECT_TOKEN
string

Defaults to 13793
