Automatically fill out product metafields

Shopify Plus

Topic summary

A user asks whether Shopify Flow can automatically populate product metafields based on tags when products are added to the store. Specifically, they want to auto-fill a material description metafield when products have certain material tags.

Solution Confirmed:

  • Use Flow’s “Product added to store” trigger
  • Add a condition to check for specific product tags
  • Use “Update product metafield” action to populate the field
  • The metafield namespace and key must be correctly configured (e.g., “custom” and “matrialebeskrivelse”)
  • The value type must match the metafield’s defined type

Additional Question:
The original poster asks if the same automation can change product templates based on tags, but this functionality is not currently available in Flow.

A new user later posts a screenshot seeking help with their Flow configuration, though no response has been provided yet. The discussion remains open with this unanswered question.

Hi There,

Yes, this can be automated with Flow! You can use the trigger “Product added to store”, use a condition to check for the tag, and finally use the “Update product metafield” action. Here’s a screenshot of what the condition would look like:
