Hi @JacklynStory, welcome to the community!
I’m assuming you’re referring to the standard built-in (optional) Shopify integration with Klaviyo’s Viewed Collection event - if so, then you can just replicate the functionality in your Hydrogen collection/category page by passing in the similar data and labelling the event as “Viewed Event”
- URL
Collection URL. - Activity ID
Activity ID for the event. - CollectionName
Name of the collection. - CollectionID
ID for the collection. - _ip_country_code
ISO 3166-1 alpha-2 (two-letter) country code (e.g., “US”). - _ip_region_code
ISO 3166-2 region code (e.g. province, state such as “MA”).
Remember, Klaviyo can take any arbitrary event at the client or server side, so depending on your site, you can pass any end user behavioral event you see fit. For example, we had a client that passed in a “Started Video” and “Completed Video’ event so they can do a “Video Abandoned Follow-up Email.” You’re on a custom implementation, so you can do whatever events (and data for each event) as you want.
