Opentrust Shopify

A Shopify app that collects and displays product reviews inside a merchant’s store. The embedded admin side is built on Polaris and App Bridge and talks to the Admin API for orders and products, while a theme app extension renders the review listing on the storefront itself.

Most of the work sat in the boundaries rather than the features: the OAuth install flow, the mandatory GDPR webhooks, and keeping the embedded frontend authenticated inside Shopify’s iframe.
