Supported metafield types

Metafields let you store custom data on Shopify resources. Hubble supports a curated set of metafield types so you can extend your Customer, Order, and Product records without running into compatibility issues.

This page lists exactly which types are supported today, how they behave, and what you can expect when using them in your store.

Why this matters

Shopify offers many metafield types, but not all are supported everywhere. By focusing on a core set, Hubble ensures:

• ✅ Consistency across customer, order, and product resources

• ✅ No surprises when rendering values in Liquid or Admin UI

• ✅ Alignment with what Hubble’s targeting engine uses behind the scenes

With these supported types, you can safely store, query, and display the extra data you need — without worrying about incompatibility or broken experiences.
