Steps
Generate a Customer Account UI Extension using the Shopify CLI and select the customer-account.order-index.block.render or a profile-related target appropriate for recommendations
Use the useApi hook from @shopify/ui-extensions-react/customer-account to access the customer's order history or session token if fetching personalized recommendations from an external endpoint
Call an external recommendations endpoint using the extension's network access capability (declared in the TOML configuration) and pass relevant customer context such as recent product IDs
Render the recommendations using allowed UI component primitives (Grid, ProductThumbnail, Link, Text) within the extension render function
Configure the extension's allowed network domains in the TOML so requests to the recommendations API are permitted at runtime
Deploy and install the extension, then verify it appears on the correct page within the customer account portal on a development store
Known gotchas
Customer Account UI Extensions run in a sandboxed iframe within the customer account portal; cross-origin requests to external APIs are only allowed if the domain is explicitly listed in the network access configuration
The available targets for Customer Account UI Extensions are more limited than Checkout UI Extension targets; not all logical page locations have an extension target exposed
Access to detailed customer PII within the extension is restricted; use the session token approach to fetch personalized data server-side rather than relying solely on extension API hooks
