Based on the knowledge sources provided, there isn't specific information about using a webhook to start recording a session when a user logs in. However, I can provide some relevant information about starting session recordings in Mixpanel:
For web applications, you can programmatically start session recordings using the Mixpanel JavaScript SDK. According to the Mixpanel SDKs: Javascript documentation, you can use the mixpanel.start_session_recording() method to begin capturing replay data.
If you're using server-side tracking, you could potentially set up a system where your server receives a webhook when a user logs in, and then triggers the session recording start on the client-side. However, this would require custom implementation on your end, as it's not a built-in feature of Mixpanel.
For more control over when to start recording sessions, you might consider using the sampling method or implementing custom logic in your application to decide when to start recordings.
If you need more specific information about integrating webhooks with session recordings, I recommend reaching out to Mixpanel's support team for detailed guidance, as the provided knowledge sources don't contain enough information to fully answer your question about webhook integration for session recording starts.
