How do you preview a product template with ?view= in Shopify?

How do you add ?view= to a product URL?

Shopify's developer docs say alternate templates can be rendered on the storefront with the view URL parameter, written as ?view=[template-suffix].

1. Find the suffix: it is the middle of the file name, so product.alternate.json (or .liquid) has the suffix alternate.
2. Open the product on your storefront and add ?view=alternate to its address, as in Shopify's example /products/example-product?view=alternate.
3. Confirm which template actually rendered, using a check below.

What happens if no template has that name?

In our check on October 31, 2026, on three public Shopify storefronts, a ?view= name that no template had still returned the product page (HTTP 200) on the default template, without error. Themes can add their own logic, so treat this as what we saw on three stores.

On two of them the product had an alternate template assigned, and with the wrong name the page no longer used it. On one of those two, the template.suffix value the theme printed went from the template's name to null (Liquid's nil). A page that opens doesn't prove the template exists.

How do you check which template actually rendered?

• In the theme code: the Liquid template object's suffix gives the alternate template's name, or nil when the default template is used.
• In the theme editor: skip the URL and preview the product with a different template, using an Active or Draft product; Archived products can't be previewed.

Neither ?view= nor a preview assigns the template. You still assign it in the admin, in the product's Theme template section (Online Store template in the Shopify app).
