Shop Canvas is an infinite pannable workspace built for a big screen, a trackpad, and a scroll wheel. Pop back open on a laptop or desktop to build live Catalog API queries.
Shop CanvasSign in with Shop to send a buyer-linked token with your search. The Catalog API uses it to personalize results for that buyer.
Sign-in uses Shop's device flow: you get a short code, approve it on Shop in another tab, and this panel picks the token up. It runs through this store's app proxy, so the browser never touches a client secret and the buyer token goes upstream from the server.
Already have a catalog token — from shop auth or your own exchange? Paste it here. Same result: it goes out as Authorization: Bearer …. Stored for this tab only.
