Hi,
I have a client who is wishing to collect marketing preferences about specific interests a customer has and use these to drive better targeted communications. This has been set up via custom preference pages within the Kalviyo platform that write to custom attributes in the users profile, but the client is now looking to sync this information between Klaviyo and the primary Shopify account they host so that a customer, when logged in, can mange these preferences from within Shopify rather than having to click links in emails.
It’s not obvious from the documentation how you can add custom fields to the Shopify<->Klaviyo data sync. As a fallback I was hoping I could generate a link to the global manage preferences page from within shopify - but I can’t figure out how to do that either.
Could anyone help me with this?
