2c:T7e8,

n our front end web app we register a projectKey with every user

mixpanel.register({ projectKey: 'abc-123' });

I am trying to query for specific events with this projectkey. I am using this page to test the query but I get an empty values object
https://developer.mixpanel.com/reference/query-event-properties
This is how the URL is constructed

<https://mixpanel.com/api/query/events/properties?project_id=myid123&event=%5B%22My%20Event%22%5D&name=projectKey&values=%5B%22abc-123%22%5D&type=general&unit=day&from_date=2014-10-01&to_date=2014-10-31>

The response is this

{
  "data": {
    "series": [
      "2014-10-01",
      "2014-10-02",
      "2014-10-03",
      "2014-10-04",
      "2014-10-05",
      "2014-10-06",
      "2014-10-07",
      "2014-10-08",
      "2014-10-09",
      "2014-10-10",
      "2014-10-11",
      "2014-10-12",
      "2014-10-13",
      "2014-10-14",
      "2014-10-15",
      "2014-10-16",
      "2014-10-17",
      "2014-10-18",
      "2014-10-19",
      "2014-10-20",
      "2014-10-21",
      "2014-10-22",
      "2014-10-23",
      "2014-10-24",
      "2014-10-25",
      "2014-10-26",
      "2014-10-27",
      "2014-10-28",
      "2014-10-29",
      "2014-10-30",
      "2014-10-31"
    ],
    "values": {}
  },
  "legend_size": 0,
  "computed_at": "2024-11-01T16:58:29.678862+00:00"
}

I know we have events with this project key because i can find this data in the mixpanel UI on the Events tab.

I am also trying with the segmentation endpoint
https://developer.mixpanel.com/reference/segmentation-query
with this as the on query param
properties["projectKey"] == "abc-123"

But i get the same result
