Tracking Frontend Events and Pageviews Server-Side Only: How-To Guide

Yes, it is possible to track frontend events and pageviews server-side only with Mixpanel. However, this approach requires some manual implementation. Here's an overview of how you can achieve this: 1. Server-Side Tracking: Mixpanel recommends tracking everything possible via your servers and only supplementing with client-side tracking when necessary. This approach is more reliable and less susceptible to ad-blockers Choosing the Right Method.2. Tracking Page Views: For server-side implementations, page view tracking must be done manually. You can track page views as a single event type using a constant event_name and include different pages as an event property. This allows for better analysis Server-Side Best Practices.3. Implementing Frontend Events: To track frontend events server-side, you'll need to send the relevant data from the client to your server, and then use a server-side SDK to send the event to Mixpanel. This could be done through AJAX requests or form submissions, depending on your application's architecture.4. User Agent Parsing: To get information about the user's browser, device, and OS (which is normally captured by client-side SDKs), you'll need to parse the User-Agent header on the server-side and include this information in your events Server-Side Best Practices.5. UTM Parameters and Referrer: You'll also need to manually capture and include UTM parameters and referrer information in your events, as these are typically handled automatically by client-side SDKs Server-Side Best Practices.While this approach provides more control and reliability, it does require more effort to implement and maintain compared to client-side tracking. You'll need to ensure that all relevant data is captured and passed to your server for each event you want to track.Remember that this method may make it harder to track certain client-side actions and states, so you might need to implement additional mechanisms to capture all the data you need Choosing the Right Method.

Let me check the knowledge base for you again. One moment! 📚

Regarding cross-domain tracking in the context of server-side implementation for Mixpanel, it's important to note that this can be more challenging compared to client-side tracking. The knowledge sources don't provide specific information about cross-domain tracking for server-side implementations, but I can offer some general insights based on the available information: 1. Persistence Limitations: When using server-side tracking, you lose the ability to use browser-based storage mechanisms like cookies or localStorage across domains. As mentioned in the Install Mixpanel FAQ, cross-subdomain tracking is not possible when using localStorage, and it requires using the default "cookie" persistence option for client-side tracking.2. User Identification: The key to cross-domain tracking is maintaining consistent user identification across different domains. In a server-side implementation, you'll need to implement your own method of passing and maintaining user identifiers across domains. This could involve: - Using URL parameters to pass user identifiers between domains - Implementing a shared authentication system across your domains - Using a centralized user management system that's accessible to all your domains3. Server-Side User Identification: As mentioned in the Server-Side Best Practices, Mixpanel's server-side SDKs and HTTP API do not generate IDs automatically. Your server is responsible for generating IDs and maintaining ID persistence. You'll need to ensure that this ID generation and management system works across all your domains.4. Event Correlation: To effectively track user journeys across domains, you'll need to ensure that all events from different domains are associated with the same user identifier. This requires careful implementation of your tracking logic across all your server-side systems.5. Data Consistency: Ensure that the properties you're tracking (such as UTM parameters, referrer information, etc.) are consistently captured and passed along as users move between domains.It's worth noting that cross-domain tracking is generally easier to implement with client-side tracking due to the built-in capabilities of browser-based storage and Mixpanel's client-side SDKs. If cross-domain tracking is a critical requirement for your implementation, you might want to consider a hybrid approach that combines server-side tracking with some client-side elements to facilitate user identification across domains.For a more detailed and accurate solution specific to your use case, I recommend reaching out to Mixpanel's support team or consulting their documentation for any updates or specific guidelines on cross-domain tracking with server-side implementations.
