What are Metafields in Shopify?

In today’s e-commerce world, Shopify remains a go-to platform for entrepreneurs seeking a seamless and customizable online store. As you embark on your Shopify journey, you'll encounter various features designed to enhance your storefront. One highly customizable feature is "metafields." Whether you're a novice setting up your first store or a seasoned Shopify merchant, understanding metafields is key to unlocking unparalleled flexibility. In this guide, we'll unravel the mysteries of metafields, exploring their definition, applications, and implementation within the Shopify ecosystem.

What is a Shopify Metafield?

The concept of metafields revolves around extending Shopify's default data structure. Metafields are additional pieces of information associated with entities like products, variants, collections, customers, and orders. To understand them further, let's break down the components that define metafields:

  1. Namespace: Think of it as a folder organizing related metafields, streamlining your custom data.

  2. Key: Similar to a variable name in programming, it identifies a specific piece of custom information within a namespace.

  3. Value: The actual data stored in a metafield, which can range from text and numbers to dates and files.

  4. Type: Specifies the format of the value, maintaining consistency and accuracy.

Implementing Metafields in Shopify

To integrate metafields into your Shopify store, there are several approaches available. The Shopify Admin interface serves as a user-friendly option accessible through the admin panel, offering an intuitive interface for creating and managing metafields without the need for an advanced setup.

Alternatively, third-party apps dedicated to metafield management can be explored, providing advanced features such as bulk editing and import/export functionalities.

Another option is utilizing the Shopify API, an ideal choice for those comfortable with coding. This method offers a programmatic approach to creating and manipulating metafields, granting developers unparalleled flexibility in customization.

How to use Shopify Metafields

Once you have logged into your Shopify store, navigate to “Settings” on the left-hand sidebar:

Then click on “Custom Data”. Here you will see all the different sections where you can add metafields. For our example, we will be demonstrating how to add a Shopify product metafield.

Next go to Metafields > Product

Here you can add a definition - “Add definition”.

In our example, we will create a “Color” product metafield definition:

Fill in the “Name”. The “Namespace and Key” will automatically be filled with “custom.” and whatever you have written in the “Name” field. So in our example it is “custom.color”. However, you can change this if you want to but ensure that you are achieving consistency across your metafield definitions.

Then we will select the “type” - here we want “single line text” but other options include “integer”, “decimal” and “product” to name a few.

Scroll down and click save. You have now successfully create a product metafield definition.

We can now head over to our products page > click on any product > scroll down and see in the “Metafields” section that we have now have the “Color” metafield available:

One thing to note is that if there is a metafield you no longer want to display in the products then you can head back to custom data > click on the metafield you want to hide > then untick the box that says “Storefronts”.
