Shopify Cart URL Generator

A cart permalink is a link that adds specific products to a customer's cart automatically, and can apply a discount and choose a checkout style, all before they arrive. Instead of sending someone to a product page and hoping they add to cart and enter a code, you send a link that lands them at a pre-filled cart or straight into checkout. It is a standard Shopify feature built on the /cart URL, and this tool assembles the link for you.

The easiest way is to paste a product URL into the tool and press Fetch. It reads the product's public data and lists every variant with its ID, so you can add the ones you want and set quantities. If you prefer to work by hand, a variant ID is the long number you see when you select a variant in the Shopify admin, or in the value of the variant dropdown on a product page. The link needs the numeric ID, not the product handle.

Two toggles change where the link lands. Shop Pay checkout sends the customer straight into an accelerated Shop Pay checkout, which works well for a known, high-intent audience. Redirect to cart takes them to the cart page rather than checkout, which is better when you want them to review the order or keep shopping. Leave both off and the link uses Shopify's default behaviour. You cannot use both at once, so turning on Shop Pay clears the redirect.

Yes. The custom parameters section lets you append any key and value pairs to the link, which is how you add UTM tags like utm_source and utm_campaign so the traffic is attributed correctly in your analytics. Those values are safely URL-encoded for you. Discount codes and checkout options are added automatically in the format Shopify expects.

The fetch reads a product's public JSON, the same data anyone can see on a storefront, and it runs in your browser. Nothing is sent to us. It works on most Shopify stores, but some block cross-site requests, in which case the fetch will fail gracefully and you can enter variant IDs by hand. As a safety measure, any text or image the tool displays from a fetched product is escaped before it is shown, so a malformed product listing cannot do anything unexpected on this page.

No. The tool runs entirely in your browser and nothing you enter is sent to a server. Your inputs are saved in your browser's local storage so they survive a refresh, and the link you build is yours to copy and use wherever you like.
