Hi Tiago A., Please stand by as I search the Mixpanel knowledge base for an AI-powered answer. I normally take about 15 seconds or so. In case AI cannot answer your question, feel free to reach out to Mixpanel support at mixpanel.com/get-support.

Yes, you can create a cohort based on an event property filtering on the first time a user did a specific event in Mixpanel. This functionality is available through the "First Time" filter feature. Here's how you can do it: 1. Use the Cohort Builder: You can create cohorts using the Cohort Builder, which allows you to define cohorts based on precise conditions.2. Apply the First Time Filter: When setting up your cohort criteria, you can add a First Time Filter to any event. This filter will consider only the first instance of the event performed by a user.3. Add Property Filtering: You can then add additional filtering based on event properties for this first-time event.According to the Mixpanel documentation: "You can do this by adding a First Time Filter to any event in Mixpanel. This filters the event down to only the first instance of the event performed by a user."The documentation also notes that Mixpanel computes this on-the-fly by scanning each user's history to determine if this was the first instance of the event performed by the user, based on timestamp.This feature allows you to answer questions such as: - How many users sign up or perform another key event for the first time each week? - Which referrers do most first-time users come from? - How quickly do users make a purchase after their first time engaging with the app?By using this First Time Filter in combination with event property filtering, you can create highly specific cohorts based on users' first-time interactions with your product.

To answer your question about the order of application for the First Time filter and event property filter, I need to clarify that the knowledge sources don't provide explicit information on this specific aspect. However, based on the general understanding of how Mixpanel's filtering works, I can provide some insight.According to the Mixpanel documentation, the First Time filter is applied to an event to consider only the first instance of that event performed by a user. This suggests that the First Time filter is a fundamental part of the event selection process.When it comes to the order of operations, it's likely that Mixpanel applies filters in a way that maintains the integrity of the "first time" concept while also respecting property filters. However, without explicit documentation on this, we can't be certain of the exact order.If you need a definitive answer on whether the First Time filter is applied before or after the event property filter, I recommend reaching out to Mixpanel's support team directly. They would be able to provide you with the most accurate and up-to-date information on the specific order of operations in their filtering process.
