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.

Hi @TyW will shopify publish any official docs about the cart permalink?

Thanks for this...this is partly what I'll need. However, we are running Shopify in headless mode. This means we don't have a store on Shopify all we use are buy-buttons.


So when I use the buy-button builder I can check that it directly forwards to the checkout-page. Do something like:


Which then includes the product I selected before via pressing the button. This forward to the checkout page will be initiated when you set "buttonDestination": "checkout" in your setup.


When I use the instructions on this page, it tries to open the Shopify webstore pages which we don't have and which is not exactly what I need. Is there any way to add a product via a link and then go to the checkout page?


Thanks, Carsten

@TyW  Thanks for the article.

This is something that would work really well for our unique situation because we want to introduce an additional step before checkout. The one checkout attribute that seems to be missing from here is the State/Province. How can we set that using permalinks?

Thank you for the article. However, as mentioned by the previous poster, we are not able to set the Country/Region and Province fields.


How can we set this using the permalinks?


Thank you!

This is a fantastic guide, thank you. 

Unfortunately when I attempt to follow it I am redirected to checkout immediately with that single item.

I am looking to simply add the item to the cart.

@brendonwbrown Did you find a way to add the item to the cart?

Indeed I have!

Get your variant ID as in the tutorial above and format your url as below:[]=variantid


You can add multiple products[]=variantid&id[]=variantid&id[]=variantid

How to add custom currency for checkout url?

@TyW Thanks for the helpful post. It looks like your original post uses the term "cart" in many places where it should say "checkout".



Using a permalink in the way you state:


does not load anything into the cart cookie for Shopify as a user  would think by reading "pre-load cart."


Rather using this permalink initiates a new checkout with the items in the URL.


Consider reviewing and updating your original post to state that "Use permalinks to pre-load the checkout"


If Shopify added a feature to add the checkout permalink's items to the cart cookie then your post would be closer to accurate. Here's more on that issue:

I've been able to add multiple items w. differing quantities to cart by using the below:[variant_id]=qty&updates[variant_id]=qty&updates[variant_i...

replace variant_id & qty


However, the problem is that it adds these items in addition to the already existing items in the user's cart.


How do I construct the URL so that shopify clears all the items in the user's cart & then add the selected items. I intend to share this URL as a Whatsapp message/share & hence, needs to very simple for users.


Any help would be much appreciated!

@danstoj Did you find a way to do a discount and conversion tracking in the one link?


The article says "Notes, cart attributes, and tracking parameters can be added as query parameters as usual," but it's not working for me. 


For example, this adds the products & quantities to checkout, but doesn't apply the discount:



If I remove the ? it does apply the discount. Anyone know what I'm doing wrong?

Has anybody noticed that when you use a checkout page permalink the "cart" link at the top is still active? When clicked it just goes to a blank cart. I feel like this is a checkout bug right?

Happy to hear about your crazy ideas.

I have a similar question. I'm able to add multiple items to cart but when I append ?ref= , I dont have get this reference on order conversion.


A sample URL that I'm using:[33826291384458]=1&updates[32056616124554]=2?ref=whatsappS...


Any thoughts?

@bradlau and @ngoenka You should be using a "&" instead of another "?" in your parameters. 


For example,

@JAS_Technology Semantics if we call it a bug or an oversight. Either way, something Shopify should fix this.


If you're curious why the checkout permalink described in the original post causes this read more here.


If the original post went to the cart as the author suggested it would load Shopify's cart, going straight to checkout seems to clear the cookie and ignore the new contents entirely.  It's likely Shopify never considered a user starting a checkout and not completing it in one direction. Have you tried just getting a 100% checkout conversion rate? 😄

Thanks but it doesnt help me put a ref in for conversion tracking. I even tried putting a &tags=<sometext> but this doesnt add tags to the order which is generated when customers go through this link.


I've basically created a whatsapp share message for users to send a product to their friends. The friend can simply click the message, add the products to cart, review & checkout. I want conversion tracking on this so that I can understand the efficacy of this flow.


any suggestions?
