Getting the app running takes three steps: install it from the Shopify App Store, activate the Yuko extension (app embed) in your theme, and add the Yuko Order Limit block to your product template. The app’s dashboard tracks all three steps in the Setup Guide and detects automatically when each one is complete.
1

Install the app

Install Yuko Order Limits from the Shopify App Store and approve the requested permissions. After installation, the app opens inside your Shopify admin.
2

Activate the Yuko extension (app embed)

The app embed powers limit enforcement on your product pages, cart drawer, and cart page.
  1. In the app’s dashboard, find the Activate Yuko extension step in the Setup Guide and click Enable. This opens your theme editor with the embed ready to activate.
  2. In the theme editor, click Save.
  3. Back in the app, click Refresh Status — the step shows Enabled once it’s active.
You can also do this manually: in your Shopify admin, go to Online Store → Themes → Customize, open App embeds (puzzle icon in the left sidebar), and toggle on Yuko Extension.
3

Activate the Yuko block on your product template

The app block displays limit messages directly on your product pages.
  1. In the Setup Guide, find Activate Yuko block and click Activate. This opens the theme editor on your product template with the block ready to add.
  2. Position the block where you want the limit message to appear — typically near the add-to-cart button — and click Save.
  3. Back in the app, click Refresh Status.
To add it manually: open the theme editor, switch to a Product template, click Add block in the desired section, and choose Yuko Order Limit from the Apps section.

Verify everything is active

On the dashboard, the Active App Block(s) card shows the live status of both pieces:
  • Yuko Order Limit extension — the app embed
  • Yuko Limits banner for product pages — the product page block
Both should show Enabled. Use Refresh to re-check at any time.
When both show Enabled, you’re ready to create your first limit.

​
Which piece does what?

​
Checkout validations

The app enforces limits at checkout through Shopify checkout rules (validations) — one per limit type, named Yuko Product Limit, Yuko Collection Limit, and Yuko Order Limit. These are added automatically when you install the app, and you can see them in your Shopify admin under Settings → Checkout → Checkout rules. If a validation is ever missing — for example, it was removed manually — the limit editor shows an Enable Checkout Rule button at the top of the affected limit. Click it to re-add the validation; it opens the right page in your Shopify checkout settings with the rule ready to activate.
Without its checkout validation, a limit still shows messages on the storefront but won’t block checkout. If customers can complete orders that break your rules, check for the Enable Checkout Rule button first.
