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:
Hello again! Using the metafield you mentioned (custom.matrialebeskrivelse), the metafield namespace is “custom” and the key is “matrialebeskrivelse”. What is configured for “Value” and “Type” depends on the metafield (just make sure the type matches what is set for the metafield).
Thank you very much! Is it true that it is not possible to do the same but with product templates instead of product metafield? Changing the template if the product has a specific tag.
For anyone landing here looking for a way to auto-fill product metafields:
Shopify Flow works if you have a small number of rules (e.g., “if tag = cotton, set material metafield to Cotton”). But it gets unmanageable fast once you have dozens of product types or attributes to fill.
I ran into this exact problem and ended up building VisionTags. It uses AI to look at your product images and auto-fills tags and metafields based on what it sees, no manual rules needed. Works well for large catalogs where setting up individual Flow automations is not realistic.
@Michael42 happy to help with your Flow setup too if you are still stuck on it.
