Conclusion

By following the steps outlined in this guide, you can effectively integrate the Audiencelab NodeJS SDK and begin tracking performance events.

• Register each user once so Audiencelab can attribute future events correctly.
• Send session-start on launch or foreground so Audiencelab can track retention.
• Send events with stable event IDs; retries must reuse the same logical event id.
• Use FetchToken only when you need to inspect registered user attribution details.
• Store durable customer context with whitelisted properties during registration and pass sensitive one-off fields with per-event blacklisted properties.
