What is a cart permalink?

A cart permalink takes your customers directly to the first page of the checkout screen with items pre-loaded into their cart.

Have you ever wanted to link directly to the Shopify checkout screen with a specific cart already loaded with items? Have you ever wanted to put a "Buy it now" button in blogs and newsletters? Have you ever wanted to provide an easy reorder link to customers? Cart permalinks are the answer.

This is what a cart permalink looks like:,70881382:1

Where 70881412 is the product variant's unique ID and 1 is the quantity.

So the format of the url is:{variant_id}:#{quantity}(,...)

Appending cart and checkout parameters

You can pre-fill any of the checkout fields, simply by appending checkout query parameters in the cart permalink URL. When appending checkout query parameters, use the following URL format:


where [email] represents any of the possible checkout fields in the form, and [shipping_address][city] shows how you can use nesting to populate child fields.

List of supported checkout parameters

You can pre-fill any of the following query parameters:

Checkout parameter Description
checkout[email] Email of the customer making the checkout.
checkout[shipping_address][first_name] Address [first_name].
checkout[shipping_address][last_name] Address [last_name].
checkout[shipping_address][address1] Address [address1].
checkout[shipping_address][address2] Address [address2].
checkout[shipping_address][city] Address [city].
checkout[shipping_address][zip] Address [zip].

Applying a discount

You can directly apply a discount to a cart permalink.

The following format applies the discount:


where test is the string value of a discount code.

Note: Notes, cart attributes, and tracking parameters can be added as query parameters as usual. If customer accounts are enabled on your website, and the user is not logged in, they will see the login page before reaching the checkout.

Adding a "Buy this" link to a blog post

  1. From your Shopify admin, go to Online Store > Blog Posts.
  2. On the Blog posts page, either add a new blog post or click on an existing blog post.
  3. In the Rich Text Editor, under the "Content" header, click the HTML button:


  4. Add your link. It should look something like this:

    <p><a href="">Buy this item</a></p>
  5. Save your changes and test it out in your store.

Adding a "Reorder" link

You can add a "reorder" link right in your theme's customers/order.liquid template for each line item in the order.


  1. From your Shopify admin, go to Online Store > Themes.
  2. Find the theme you want to edit, and then click Actions > Edit code.
  3. Under the Templates folder, locate and click on customers/order.liquid to open it in the online code editor. Don't see the template? Create one by clicking the Add a new template link.
  4. In the online code editor, paste the following piece of code where you would like your link to appear:

    <a href="/cart/{{ line_item.variant_id }}:{{ line_item.quantity }}">Reorder this</a>


  5. Click Save to confirm your changes.

Conversion tracking

Wish to add some tracking info to the URL, which will then show up on the order details page in your admin, when orders come in?

Use a cart note:


Or use a cart attribute (you can have several of those):


The cart note and cart attributes are shown on the order details page under Order Note.

Or use the 'ref' parameter:


The ref value is shown as a referral code in the Conversion summary section on the order details page. Click View conversion details and then click View full sessions to view the session details page:



Sales attribution

To attribute an order to a sales channel or app, you can add an additional parameter to the permalink. You can view sales attributions in the Sales by Channel report, which shows the name of the channel or app that the customer used to place their order. Sales attributions also appear on the sidebar in your Shopify Home. You can specify a storefront access token in the cart permalink as shown in the following example:


Can I let the customer edit quantities?

You can't. Quantities cannot be edited when the customer follows a cart permalink.

Does the cart URL (not checkout) support adding a coupon code? 

The "discount=code" in the checkout URL format works fine but I can't get it to work for any cart URLs. 

Is it supported?

@chenster ya i saw your post and bookmarked it but it didn't address coupons in the cart urls. Other posts on the web seems indicate the "discount=discount-code" parameter works but I've never had it work. 

I guess you could use the coupon url then redirect to your cart URL?
