Updating a Serialized Product Metafield
This flow is an easy workaround if you want to bulk update the metafield value to 'true' for serialized products. This flow automatically sets a metafield to "true" for products tagged as "serial" when their inventory changes, helping identify serialized items with less manual effort.
The Flow:
Tag all products that need to be marked as serialized with the word "serial."
In Shopify Flow, implement the flow above. This flow triggers when inventory changes for those tagged products and sets their metafield value to true.
Manually update the inventory (for example, increase by 1) to trigger the flow.
After the metafields are updated, turn off the flow.
Reset the inventory back to its original amount if needed.
Remove the "serial" tag from the products to finish.
