Enable the app
Before your limit rules show up on your storefront, you need to activate the app in your theme.
Activate the app embed
- Open the Pareto admin app. If the app isn't activated yet, you'll see a yellow warning banner on the Dashboard that says "Action required."

- Click "Activate Now" on the banner. This takes you directly to the Shopify Theme Editor.

- In the Theme Editor, find Pareto Limit Purchase in the App embeds section on the left panel.
- Toggle it on.
- Click Save in the top right corner.
Tip: If you skip this step, your limit rules won't appear on the product or cart pages — even if the rules are set to Active.
Add the app block to your Checkout page
(optional - for non-Plus stores using Checkout Validation)
- In your Shopify Admin, go to Online Store > Themes.
- Click Customize on your active theme.
- At the top of the Theme Editor, switch the page view to Checkout.

- In the left panel, click Add app block.
- Find and select Pareto – Payment Limit.
- Drag it to the position you want in the checkout layout.
- Click Save.
