The HIU (High Intent User) event is a smart, AI-powered event generated by Nitro to help brands retarget users based
on their real-time behavior on the website. When users demonstrate strong purchase intent (such as product views, cart
activity, or checkout initiation), Nitro tags them as HIUs and sends a structured event to the connected CRM.
A user gets tagged as an HIU when their actions match intent signals such as:
● Viewing specific product or category pages
● Adding items to the cart
● Initiating checkout
● Browsing high-value items
● Repeated visits in a session
These are then sent as a hiu_tagged event to the CRM with detailed metadata.
Below are all the different payloads sent depending on the user’s last recorded activity.

The HIU event acts as a strategic event for CRM platforms to prioritize and personalize outreach to users most likely
to convert. These users have already demonstrated meaningful engagement, and the goal is to strike while the intent is
high.
● These users have shown recent, measurable interest in specific products or categories.
● They’ve performed mid-to-bottom funnel actions (like product views, add-to-cart, and checkout initiation).
● Retargeting them within minutes to hours can significantly lift conversion rates.
● Trigger Dynamic Campaigns:
○ Send personalized WhatsApp/SMS/Email within minutes of the HIU event.
○ Highlight the exact product(s) they viewed or added to cart.
● Use Purchase Triggers:
○ Offer exclusive limited-time discounts or incentives.
○ Send cart recovery messages if the event was "add to cart" or "checkout".
● Score & Prioritize Leads:
○ Tag HIU users as high-priority leads for remarketing and remarketing workflows.
○ Use segmentation logic to run specialized offers only for HIUs (e.g., free shipping, bundled pricing).
● Higher open, click, and conversion rates
● Lower CAC compared to cold segments
● Improved ROI on retargeting workflows
HIU events bridge the gap between intent and conversion — giving CRMs a real-time edge in winning
high-value customers.
