Trouble syncing engagement data from external game-related tools into klaviyo

Hey everyone,

I’ve been trying to connect some external web tools into my klaviyo flows so I can track user engagement, but I’ve hit a bit of a wall with one of them. I was testing something that uses rblx scripts.

The main issue is that the scripts generate a lot of activity on the client side, but none of that seems to come through cleanly into klaviyo for tracking or segmentation. I suspect it’s because the scripts load dynamically and don’t trigger standard pageview or event tracking the way a normal website would.

Has anyone here dealt with tracking or syncing data from game-related or script-based tools like this? I’m trying to figure out whether this needs custom API calls, webhooks, or some kind of middleware to make klaviyo actually recognize what users are doing.

Would love to hear how others approach this kind of setup.

I think your suspicion about client-side activity is probably on the right track. Instead of relying on pageviews, I’d define the specific actions you want to track as custom events and send them to Klaviyo through its Events API. Klaviyo supports custom events that can be used for both segmentation and flow triggers.

For dynamically loaded tools, a small middleware layer can also be useful if the events need to be processed or normalized before reaching Klaviyo. I’ve also found it helpful to keep the external tool separate from the marketing tracking layer. For example, if you’re testing different game-related tools, you could use this resource independently while sending only the relevant engagement events to Klaviyo.
