Hi @sherbert!

I’m going to look into this with Engineering and I’ll update the thread as soon as possible!

OK thanks!

Hi @sherbert!

Sorry for the delay here! In the field you referenced, “custom properties” refers to custom profile properties that are attached to a profile. In other words, they’re just profile properties that you create and set yourself. Here’s our Help Center article on this:

• Understanding custom profile properties

However, integrations with Klaviyo typically work one way - from the e-commerce platform (Shopify) to Klaviyo. Although there are a few exceptions, it will usually require a customization (which is beyond the scope of support/community) to achieve this. A more detailed explanation of this can be found here:

That said, there are possible workarounds, but most of them will require the help/knowledge of a developer. One method could be to use a webhook, which is a development tool used in flows that allows you to export data out of Klaviyo. If you decide to attempt this and are looking for extra development help, you’re always welcome to reach out to one of our wonderful Official Klaviyo Partners.

I hope this helps to clarify, and thanks for using the Community!

To send tags or custom fields from Klaviyo to Shopify, you can utilize Klaviyo's integration with Shopify features for data synchronization.
