Does Shopify Store-to-Store Sync automatically create metafield definitions?

Yes, this is supported only when using the Shopify Store (requires Stock Sync app) connection method.

When syncing between Shopify stores using this method, Stock Sync compares the metafield definitions in the source (main) store with those in the destination (sub) store. If a metafield definition exists in the source store but is missing in the destination store, Stock Sync can automatically create the missing metafield definition in the Shopify admin of the destination store.

However, this process only creates the metafield definition in Shopify. You still need to:

• Map the metafield in the destination store, and
• Enable the option “Auto create metafield definition if not found” in the feed settings.

This behavior does not apply to other connection methods such as CSV, XML, Google Sheets, or other file-based feeds.
