How to Connect ReviewHub with Stamped

Follow this step-by-step guide to integrate your Stamped reviews with ReviewHub, sync your product catalog, and enable review syndication to retail partners like Walmart, TikTok, and more.

1. Sync Your Product Catalog from Shopify

Before ReviewHub can syndicate reviews, your product catalog must be synced from Shopify.

Steps:

  1. Ensure ReviewHub has the necessary collaborator access to your Shopify store.

  2. Provide your Shopify store URL and collaborator access code to our onboarding team.

  3. Once connected, ReviewHub will automatically pull your product data for mapping and syndication.

Tip: Verify that your product catalog includes complete product identifiers (UPCs or SKUs) for each item you want syndicated.

2. Configure Walmart Syndication

To syndicate reviews to Walmart, your account must have at least one valid Walmart identifier:

  • Partner ID

  • Seller ID

  • Supplier ID

Any one of these is sufficient to connect. If you’re unsure where to find them, consult Walmart Seller Center help docs or your Walmart account rep.

Important: Walmart syndication is driven by UPC matching.

  • Make sure your Shopify catalog contains the correct Walmart UPCs for each product.

  • If you sell bundled products on Walmart, ensure that the UPC for the Walmart bundle is also assigned to the individual Shopify products that should share those reviews.

3. Configure TikTok Syndication

Download and connect your ReviewHub account with your TikTok Storefront. Access the ReviewHub TikTok App here. Login to your ReviewHub account to authorize access. If you do not yet have access to ReviewHub, contact ReviewHub for access.

TikTok product sync through ReviewHub requires UPCs or SKUs in your Shopify catalog. Ensure these are present before attempting integration.

4. Retrieve Your Stamped API Keys

ReviewHub connects to Stamped via API credentials from your Shopify account.

Steps:

  1. In Shopify, go to Apps > Stamped.io.

  2. Navigate to the API settings or credentials section.

  3. Provide ReviewHub with the following:

    • STORE_HASH

    • PUBLIC_API_KEY

    • PRIVATE_API_SECRET

5. Final Steps

Once all connections are in place:

  • ReviewHub will authenticate and moderate your reviews.

  • Reviews will be syndicated to connected retailers via UPC mapping.

  • Any updates to your product catalog in Shopify will automatically sync to ReviewHub for ongoing syndication.
