Syncing Metafield Definitions

Q) Why are some metafield definitions showing as not supported?

• In order to make metafield sync available as soon as possible, we have decided to focus on the most common metafield definitions.
• We will send out notifications as new definitions are added.

Q) Shopify's maximum supported metafields is 200, why can I only sync 50?

• Syncing metafields is Shopify API intensive. The goal is to sync metafields without impacting higher priority syncs like: orders and inventory.
• 50 product and variant metafields (100 total) is just the starting point; we plan on increasing this limit as the feature becomes more mature.

Syncing Metafield Values

Q) The metafield on Syncio is currently marked as "synced"; why are values not showing up on my synced products?

• In order to sync metafields efficiently and reliably, values and definitions are synced separately.
• In most cases, your values will auto-sync whenever a source product has been updated.
• Syncio batches metafield changes every 60 minutes for a once per day update to help avoid slow downs with your Shopify API.

Managing Metafield Syncs

Q) What happens to my synced metafield definitions and values if the source store disconnects or uninstalls?

• Syncio will not delete the synced definition and its associated values. Once you sync a metafield definition, you are in full control of that definition.

• You will be left with the definition to use as you see fit:

• Delete it if no longer required.

  • Use it to add metafield values to other products or variants from different source stores or your own.

Q) I have synced a metafield definition from a source store. Can I add metafield values to a product that is from another store?

• Yes. Once synced, you are free to use the definition as needed.

• Any products that are synced from the source store where the metafield was synced from will receive auto metafield value syncs.

• You can use this newly synced definition to add values to any unrelated product.

• For example: If you synced a size guide metafield from Source store A, you can add metafield values to products that you own or from other source stores.

Metafield Syncs for Universal Stores

Q) My Syncio account is a universal store (both source and destination). Why can't I share metafields that have been synced from other source stores?

• Since a synced metafield is controlled by another source store, to prevent issues with double syncing and errors. You can only sync original metafields from source stores.
