Something does not look right?
Common questions in your own words, with what to check. Guide reviewed 9 October 2026.
I cannot open Headless
Ask the store owner to check your account’s sales-channel permissions, or use the Connect Shopify approval route, which creates the public token for you. A permission error is not a reason to use a private or Admin token.
I do not see the Connect Shopify button
Sign in to Shop Canvas in the plugin first: Connect Shopify appears once you are signed in. Or connect with the three fields instead, no account needed: the permanent .myshopify.com domain, the public Storefront token from Shopify’s Headless channel, and the two-letter country code for your market.
My product is missing
Check Shopify product status, Headless publishing and market availability, then run another Preview product changes. Also confirm that the plugin points to the intended store.
Everything says sold out
Check stock, variant availability and the selected market. For physical goods, also check shipping coverage. If the current plugin blocks an all-digital store with a shipping-zone warning, contact support; do not invent physical shipping settings.
The price or currency is wrong
Check the Connect country and Shopify Markets. The current plugin defaults to AE; choose your intended country, reconnect, resync and regenerate the snippet together.
I see a duplicate URL warning
Do not apply yet. A slug is the final part of a page URL. Resolve the conflict and run another preview before writing product updates.
The page looks right but the cart is empty
Check the published URL, that one Shop Canvas commerce script is saved in Custom Code at Start of head (Show published site in Store → Cart & checkout setup gives you the link to check), the product’s CMS binding and its Product ID. A design preview can look complete before commerce is connected.
