Add a return portal to Shopify customer accounts

Choose one of three entry points

Add the Opus order action

1. Install Opus and save the store's basic return settings.
2. Open Shopify's checkout and accounts editor.
3. Add the Opus order action to the customer order menu.
4. Save the customer-account configuration.
5. Sign in as a test customer with a fulfilled order and open the action from that order.

Opus uses Shopify customer-account UI extensions for the order action, the order-specific request page, and return details. The customer stays inside Shopify's authenticated account experience.

Add a general portal link

Some account-page tools let a merchant add a custom menu item, tile, or page. Point that element to the store's own signed Opus proxy path, not to the Opus hosting domain:

https://YOUR-STORE.myshopify.com/apps/resolve

• Label it “Returns & Exchanges” or “Order help”
• Open it in the same tab unless the account tool requires otherwise
• Do not paste a Railway or internal application URL
• Keep Shopify's app proxy enabled

Test the customer path before publishing it

1. Create a fulfilled test order for a customer account.
2. Sign in as that customer in a private browser window.
3. Open the order action and the general portal link.
4. Confirm the correct order and eligible items appear.
5. Submit a clearly marked test request.
6. Confirm the request appears in Opus without exposing another order.

Do not install an app just to duplicate Shopify

Current Shopify customer accounts already let customers view and manage orders and can support self-serve returns. Opus is useful when the merchant needs a different request shape or operating workflow. If the native return action is sufficient, use it.

Platform details can change. Check Shopify's current customer account settings and the store's plan before publishing the workflow.
