How to use Flow to add product to a collection based on metafields

Shopify Plus

Topic summary

Goal: Automatically add products to specific collections when product metafields indicate they belong there. Metafields = custom fields on products; Shopify Flow = automation tool for triggers, conditions, and actions.

Key guidance:

  • It’s possible to base collection assignment on metafield values.
  • For bulk/automated updates, build a Flow that:
    1. Uses a Scheduled time trigger to run periodically.
    2. Calls Get product data to retrieve products.
    3. Applies Conditions to check each product’s metafield values.
    4. Runs a For each loop over matching products.
    5. Executes Add product to collections to place each product into the relevant collection(s).

Notes:

  • An illustrative screenshot (flow diagram) was provided showing the trigger → data fetch → conditional checks → loop → add-to-collection actions.
  • This approach addresses cases where the UI appears to only allow manual assignment by automating it via Flow actions.

Outcome/status: The original poster acknowledged the guidance with thanks, indicating the solution answered the question. The discussion appears resolved.

Hi,

Let’s say I have metafields of collection 1 and collection 2 on products. How can I use flow to check for those metafields and if they exist, add the product to those collections? I see the option to manually add the collection but not to automate it with metafields. Thanks!

You can just define the collection based on those metafield values.

If you want to run bulk updates manually, you could start with a Scheduled time trigger and a Get product data action. Then you’d want to define conditions that evaluate the returned products for the desired metafield value and start a For each loop that executes an Add product to collections action for each product and adds it to the relevant collection.

Here’s an illustrative example:
