    I can see you're having an issue with events being sent to Mixpanel but not appearing in your Mixpanel dashboard. Let me help troubleshoot this issue based on the curl request you've shared.

    Possible Reasons Your Events Aren't Showing Up

    1. API Endpoint: You're using [api-js.mixpanel.com](http://api-js.mixpanel.com) which is correct for the JavaScript SDK.2. Project Token: The request includes a token (aae4ee569c88c0e1c37275cdd5148a77). Make sure this token matches the project where you're looking for the events.3. Verbose Parameter: Your request includes verbose=1, which should return a response indicating success or failure. Check the response you're getting from this request.4. Event Timing: There can be a delay between when events are sent and when they appear in the Mixpanel interface. The events in your request have timestamps from around the time of sending.5. Data Views: Check if you have Data Views configured that might be filtering out these events.

    Troubleshooting Steps

    1. Verify the response: Since you're using verbose=1, check the response from Mixpanel. A successful response should return 1, while a failure returns 0 with an error message.2. Check project token: Confirm you're looking at the correct project in Mixpanel where this token is configured.3. Try manual flush: If you're using the JavaScript SDK directly, you can try calling mixpanel.flush() to force sending any queued events.4. Check for rate limiting: Mixpanel has rate limits that might affect event ingestion.5. Verify event properties: Some of your event properties contain PII (like phone numbers and names). Make sure these aren't causing issues with your implementation.6. Check for IP blocking: The ip=1 parameter means Mixpanel will use the IP of the request for geolocation. If you've disabled geolocation in your project settings, this might cause issues.If you're still having trouble, I recommend checking the Mixpanel project settings and ensuring there are no data filters or views that might be hiding these events.

    if there is rate limitation why some events are coming some are not
