In short: import method succeeds but no data is stored.
Longer version
tracker.import('SECRET", '123', "Event", {"time" => 1517048470 })This returns success result, but the event is not created in mixpanel.
Curl also does not work if api_key is passed as a param. For example
curl https://api.mixpanel.com/import \
-d data=abc \
-d verbose=1 \
-d api_key=123
The documentation uses curl example with basic authentication and it works like that: https://mixpanel.com/help/reference/importing-old-events
curl https://api.mixpanel.com/import \
-u YOUR_API_SECRET: \
-d data=eyJldmVudCI6ICIkc2lnbnVwIiwgInByb3BlcnRpZXMiOiB7ImRpc3RpbmN0X2lkIjogIjQ4MSIsICJ0aW1lIjogMTMyMTQ5OTM3MSwgInRva2VuIjogIjEzZmUzZGRjODZlYjZmOTBjNGVlN2QwZDQ3NTYzMTUwIn19 \
-d verbose=1
So my assumption that api_key param is ignored and basic authentication should be used instead
