Add a metafield to customer

Shopify Plus

Topic summary

A user wants to automatically assign customers to one of two metaobjects (“warm colors” or “cool colors”) based on their favorite color selection from a registration form.

Proposed Solution:

  • Set up a Shopify Flow workflow with a “Customer Created” or “Customer Updated” trigger
  • Add conditions to check the selected color (e.g., red/orange/yellow → “Warm Colors”; blue/green/purple → “Cool Colors”)
  • Use “Update Customer Metafield” action to assign the appropriate metaobject

Important Limitation:
Flow doesn’t natively support metaobject references yet, so implementation may require:

  • A custom Shopify Function
  • A third-party app like Mechanic

Open Question:
One responder asked whether the user is using Customer Accounts or Legacy Customer Accounts, which may affect the implementation approach. The discussion remains ongoing with no final resolution yet.

From a registration form where I ask for the customer’s favorite color, I want to automatically assign them an existing metaobject (from a list of two choices: “warm colors” and “cool colors”).

Example: The customer selects the color red, and the “color group” metafield displays “warm colors.”

How is this possible with Flow?

Hi @tj56

You can automate this by setting up a workflow that checks the selected color and assigns the correct metaobject reference. Here’s how:

  1. Trigger: Use the “Customer Created” or “Customer Updated” trigger (depending on when the color is chosen).
  2. Condition: Add a condition that checks the customer’s selected color. If the color is red, orange, or yellow, assign “Warm Colors”; if blue, green, or purple, assign “Cool Colors.”
  3. Action: Use the “Update Customer Metafield” action to set the correct metaobject reference based on the condition.

Since Flow doesn’t directly support metaobject references yet, you might need a custom Shopify Function or an app like Mechanic to handle it

Quick question: are you using Customer Accounts or Legacy Customer Accounts?
