Automated product metafield update

Topic summary

A user needed help setting up a Shopify Flow automation to add “New in” text to product metafields when new products are created. While their tag automation worked correctly, they struggled with the metafield configuration.

Solution provided:

  • The issue was incorrect namespace and key configuration
  • In Shopify’s metafield definition (Settings > Custom data), the namespace is the part before the period (“.”) and the key is the part after
  • Understanding the proper syntax for separators (periods and underscores) was crucial

Outcome:
The original poster confirmed the solution worked after correctly identifying the namespace and key structure. Another user has since requested to see the working flow configuration for the same issue.

Are you sure you’re using the right namespace and key? In the metafield definition (under Settings > Custom data) the namespace is the part before the period (“.”) and the key is the part after.

Thank you! It worked now! I have tried any combination but couldnt figure out which exactly is the namespace and the key and also so I need to add the “.” and “_”. Thank you for your help!
