How to Make Changes on a Headless Shopify Site

Use this article when you need to update a headless Shopify site and want a clear split between safe Shopify admin changes, structured content updates, and changes that should stay in professional hands.

A headless Shopify site is different from a regular Shopify theme. Shopify explains that headless storefronts use a custom frontend through the Storefront API, while the Shopify admin still manages products, pricing, inventory, and metafields. Shopify also says the theme editor is for customizing a theme's content, layout, typography, and colors. In practice, that means most store-data changes happen in Shopify admin, while design, layout, and code changes should usually be handled by a professional.

1

Know what kind of change you need

If you are changing product information, collections, menus, pages, blog posts, images, or custom content fields, you can often do that inside Shopify admin.

If you are changing the homepage layout, header, footer, section design, custom features, animations, integrations, or code, we strongly recommend hiring a professional. Headless sites are custom-built, and the wrong change can create layout issues, broken content, or unexpected problems.

2

Change product details

Go to Products in Shopify admin. Open the product you want to change. Edit the product details. Then click Save. If you also need to change product images, videos, or 3D media, use the Media section inside the product.

3

Change collections

Go to Products > Collections. If you need a new manual collection, click Create collection, enter the title and description, choose Manual, click Save, and then add products in the Products section. If you need to update an existing manual collection, open the collection and add or remove products there. Shopify also lets you view, create, and edit collections from this area of admin.

4

Change your menu or navigation

Go to Content > Menus. Open the menu you want to change. Click Add menu item to add a new link, or edit an existing item if you need to rename it or point it somewhere else. You can also drag menu items into a new order and click Save. Shopify warns that pasting a URL instead of selecting the page directly can lead to a broken link or 404, so it is safer to choose the destination from the list when possible.

5

Change a page

If your site uses Shopify pages for content, go to Online Store > Pages. To edit an existing page, open it, make your changes, and click Save. To create a new page, click Add page, enter the title and content, choose whether the page should be visible, and save it. Shopify also notes that if you want the page to appear in navigation, you need to add it to a menu.

6

Change blog posts

If your site uses Shopify blog content, go to Content > Blog posts. Open the post you want to update, make your changes, and click Save. To create a new post, click Add blog post, enter the title and content, set the visibility or publish timing, and save it.

7

Change custom section content

Many headless Shopify sites use Metaobjects or Metafields for custom homepage sections, banners, FAQs, featured blocks, testimonials, and other structured content. If your site was built this way, go to Content > Metaobjects, open the correct definition, open the entry you want to edit, make the changes, set it to Draft or Active, and click Save. If your build uses metafields instead, open the product, collection, page, or other item you want to edit, scroll to the Metafields section, update the value, and save.

8

Change images or files

Go to Content > Files to upload and manage files used across Shopify, including brand images, product media, and metaobjects. If you need to replace a file, click the Replace icon next to the file name. If you want a safer option that keeps the original file untouched, open the file editor and choose Save as new instead of overwriting the existing file.

9

Make lots of updates faster

If you need to update many products or collections at once, Shopify has Bulk edit. Go to Products, Collections, Inventory, or Customers, select the items you want, and click Bulk edit.

10

Preview before you are done

For product updates, Shopify lets you open the product and click Preview. For pages, Shopify says you can preview after editing, and you may need to reload the browser to see the saved changes. Always check the change on desktop and mobile before you consider it finished.

Important: do not assume the Theme Editor controls a headless site. Shopify's theme editor is built for editing a theme's content, layout, typography, and colors. Headless storefronts, on the other hand, use a custom frontend powered by the Storefront API. That means Online Store > Themes > Edit theme is usually not the right place for major changes on a headless build unless LER Web Services specifically told you that a section is theme-controlled.
OUR RECOMMENDATION
  • For simple admin updates, Shopify gives you useful tools to make safe changes yourself.
  • For anything involving design, layout, custom sections, code, app behavior, animations, tracking, or advanced functionality, we strongly recommend hiring a professional.
  • Shopify's own help docs also point merchants to hire a Shopify Partner for some customization and collection setup help.
MONTHLY ECOMMERCE WEBSITE MAINTENANCE
  • LER Web Services also offers monthly ecommerce website maintenance for clients who want updates handled safely and professionally.
  • This is a good fit if you need ongoing product updates, content edits, collection changes, merchandising updates, landing page updates, or technical changes each month.
  • Time is planned around the size and complexity of the request, so smaller edits and larger changes can be handled the right way without unnecessary risk.

Best practice: when in doubt, do not guess on a live headless site. Make the simple Shopify admin changes you know are safe. For everything else, let a professional handle it.
