How to install the app

Step 1: Open the Shopify App Store

Install OO - Shipping rates & Rules from the Shopify App Store listing for your Partner / Online Origins app.

Step 2: Add the app

1. Click Add app.
2. If you are not logged in, Shopify asks you to log in to your store.
3. Select the store where you want to install the app.

Step 3: Approve installation

1. Review the permissions requested by the app (shipping, delivery customizations, products, markets, and related scopes).
2. Click Install app to confirm.

Step 4: Open the app home

After install, Shopify opens the app. The home screen shows a setup checklist so you can finish carrier setup and create your first shipping zone or delivery rule.

What the app does

• Shipping rates — return your own calculated prices at checkout via a Shopify Carrier Service named OO - Shipping Rate & Rules.
• Delivery customization — hide, rename, or reorder methods that already appear at checkout (works on more Shopify plans than carrier rates).
