What is Metafields Syncing?

When activated, Syncio's metafield syncing allows:

1. The Metafield definitions for products and variants from the source store to be copied to a connected destination store.

2. Product and Variant metafields can be synced:

3. On initial import of a new product after the [Sync] button is clicked.

   2. Continuously every 60 minutes if there is a change to be synced.

You can keep track of the metafields on the destination store's synced products by clicking into a product/ variant.

How do I use Metafields sync?

The Metafields option can be found under:

You can see the metafields that can be synced over.

Once the setting is turned on, please try syncing a test product to check if your metafields sync over.

Syncio will then request for Shopify to scan and bring over all supported metafields to any synced products after 60 minutes.

Considerations

• Shopify limits 200 metafields per store.

• Syncio is only able to sync the first 50 metafields.

• Updates from ongoing metafields sync should complete within 60 minutes.

• Syncio prioritises Shopify network resources for order, stock and standard Shopify fields first.

• New! Syncio will not overwrite content from matching metafields on destination store only, and will avoid updating metafields that are unique on the destination store.

• Example: If the destination store has an exclusive metafield for USA size guides, Syncio will leave this metafield alone.

• In summary metafields sync aims to only copy and sync new metafields and content from source and destination.

Supported list of metafields

In addition to the above conditions with the number of metafields Syncio can sync, here a current list of supported metafields:

*Ensure that the units are the same on both source and destination store metafield definitions.

** We currently do not have permission to sync metafield content that is exclusive to a specific store, for example: a blog page, or product collection.

However, our team is working hard on finding solutions to cover as many metafields as possible.

Should I use metafields sync?

Metafields syncing is best for multi-store use cases. We recommend using metafields syncing if your Shopify stores require a one to one copy of metafields data across all stores.

Metafields syncing is not recommended if you require unique metafields. For example: if your Shopify stores are in different languages.

Additionally for stores using Syncio for dropshipping purposes, we recommend not using this feature as syncing metafields from the source store may add product data that is not useful to the destination account.

Recommendations

Since the current version of metafield sync aims to sync all supported product and variant metafields from source to destination.

Metafields sync is best for destinations that do not have any metafields yet.

For stores already populated with metafields, we have plans to implement additional controls to allow you to pick and choose which metafields to sync over in the near future.

If you have any questions about using this feature, please reach out to: support@syncio.co, or send us a message in app to discuss your needs.
