# Product reviews with Okendo

Use the product review feature of the Okendo app

1. **How to Obtain:**
   * This is only useful if you want to use the product review feature of the Okendo app. Otherwise, you can skip this step.
2. **Installation and Configuration:**
   1. Visit the Shopify Marketplace and search for the **Okendo: Product Reviews & UGC** application or navigate directly to  <https://apps.shopify.com/okendo-reviews>
   2. Install the application, open it, and click the **Open Okendo Platform** button.
   3. On **Okendo App** > **Settings** > **Integrations > Credentials** > **Okendo** > Click edit button then copy the *User ID* and it will be the value for the `PUBLIC_OKENDO_SUBSCRIBER_ID` environment variable in the next step.
   4. Add the environment variable `PUBLIC_OKENDO_SUBSCRIBER_ID` to your storefront\
      Managing environments  - <https://shopify.dev/docs/custom-storefronts/hydrogen/environments#managing-environments>
   5. **Expose Shopify Metafields:** Okendo Reviews uses Product and Shop [metafields](https://shopify.dev/api/examples/metafields). You will need to expose these metafields so that they can be retrieved by your Hydrogen app.

      At the moment, Shopify does not have a way of exposing Shop Metafields through their admin UI, so the preferred method is to [contact Okendo Support](mailto:support@okendo.io) and ask them to **Expose Shopify Metafields** for you, they will quickly and enthusiastically help you.
