Conclusion

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

• Always call setUserCreativeTokenInfo(response) after registration or token fetch before sending events.
• Use stable setDedupeKey() values for events your backend may retry.
• Store durable customer context with whitelisted properties and pass sensitive one-off fields with per-event blacklisted properties.
• Use shouldSendRetentionEvent() with your own persisted retention guard in multi-worker backends.
• Session events are optional, but useful when your backend can reliably provide session IDs and duration.
