how can I copy an event property to the user property

Hi Juan I., Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so.

To copy an event property to a user property, you can use the set method provided by Mixpanel's SDKs. This method allows you to set properties on a user profile. Here's an example of how you might do this in JavaScript:LBKS// Assuming you have an event property "country" for event "signup" mixpanel.track("signup", { "country": "USA" });LBKS// You can then set this property to the user profile mixpanel.people.set({ "country": "USA" });LBKSIn this example, the "country" property from the "signup" event is copied to the user profile. Remember, User Properties are as flexible as any other properties in Mixpanel, so you can send arbitrary JSON. User Profiles are mutable; Mixpanel only stores the latest value of each profile property. Please note that you should use the same Distinct ID for both the events and user profile for the same user. This lets you join the events performed by a user with user properties describing them.For more information, you can refer to the Mixpanel documentation on User Profiles and Tracking Methods.

Yes, you can do this with Mixpanel's UI feature called Borrowed Properties. Borrowed Properties allows you to "borrow" a property from one event to another on the fly, and you can analyze as though that property has been tracked on that event all along. Here's how it works:1. In the Mixpanel UI, select an event. 2. Choose to "borrow" a property from any other event. 3. The borrowed property will appear as if you tracked it all along.This feature is done at query time, so you can do it on any event, any property, at any time, and it’ll work fully retroactively. Please note that Borrowed Properties is available for customers on Mixpanel's Growth and Enterprise plans. For more information, you can refer to the Mixpanel documentation on Borrowed Properties.

Based on the provided knowledge sources, Mixpanel's Borrowed Properties feature allows you to borrow a property from one event to another event. However, there is no explicit mention of borrowing a property from an event to a user profile property.User profiles and events in Mixpanel are stored in two separate tables and are joined at query-time, not ingestion-time. This means that when you make a report in the Mixpanel UI that uses User Profiles, a query is run that joins the Events table with the User Profiles table. If you want to track changes in a user's state over time, it's recommended to track that as a property on their events, so that you can analyze that change over time.For more information, you can refer to the Mixpanel documentation on User Profiles and Borrowed Properties.

Mixpanel automatically maintains an "Updated at" ($last_seen) property on user profiles, which contains the last timestamp that a user profile was updated. However, it's important to note that "Updated at" does not change if the user does a new event; it only changes when the profile is updated. "Updated at" also does not change for profile updates made via the UI or if the $ignore_time parameter is set to true.If you want to track the last time a user logged in or did any event, you would typically do this by sending an event when the user logs in or performs an action, and then you can look at the timestamp of that event. However, based on the provided knowledge sources, it seems that this would require using the Mixpanel API or SDKs, and cannot be done solely through the Mixpanel UI.For more information, you can refer to the Mixpanel documentation on User Profiles.

Mixpanel automatically maintains a "Created at" ($created) property on user profiles, which contains the timestamp when the user profile was first created. You can view this property in the Mixpanel UI by navigating to the user's profile.However, it's important to note that the "Created at" property is only set when the profile is first created, and it does not change if the profile is updated later.For more information, you can refer to the Mixpanel documentation on User Profiles.
