To answer your question about knowing which properties of a profile have changed based on the "Updated at" field, I'll refer to the information provided in the knowledge sources.
According to the Mixpanel documentation on User Profiles, the "Updated at" ($last_seen) property is automatically maintained by Mixpanel. However, this property only indicates when a user profile was last updated, not which specific properties were changed.
The documentation states:
"Mixpanel automatically maintains an "Updated at" ($last_seen) property, which contains the last timestamp that a user profile was updated. "Updated at" does not change if the user does a new event; it only changes when the profile is updated."
Unfortunately, the knowledge sources don't provide information on how to determine which specific properties have changed since the last update. The "Updated at" field only tells you when the profile was last modified, not what was modified.
If you need to track specific property changes over time, you might want to consider one of these approaches, though they are not directly supported by Mixpanel's standard user profile functionality:
1. Track property changes as events: You could send an event each time a profile property is changed, including both the old and new values as event properties.
2. Use Profile History: As mentioned in the Mixpanel documentation on importing historical profile values, you can use historical properties to capture changes in each property over time. However, this requires setting up a separate process to import these historical values.
To get more detailed information about tracking property changes, you may need to reach out to Mixpanel's support team or consider implementing a custom solution that fits your specific needs.
