Overview

Klaviyo already lets you send abandoned cart emails when a customer leaves items in their cart without completing checkout. By connecting Growave Reviews to Klaviyo via Web Feeds, you can display 5-star customer reviews for the products left in the cart. This extra layer of social proof can encourage customers to return and complete their purchase.

How to use Web Feeds with Klaviyo

Prepare your Web Feed in Growave

Go to the Growave admin → Integrations → Klaviyo.
Find the Klaviyo Web Feed option. Click Enable product reviews feed. Allow one hour for the feed to populate before using its URL in Klaviyo.
Copy the feed URL provided for your store. This link dynamically pulls in product review data.

⚠️ Important

Each Web Feed is tied to your main store domain. If you use multiple currencies or subdomains, the feed may only display reviews for the main store setup.

Set up Klaviyo Web Feeds

In your Klaviyo admin, click your company name in the bottom-left corner.
Go to Settings → Other → Web feeds.
Click Add web feed.
Fill in the fields:
- Feed name: use GROWAVE_PRODUCT_REVIEWS
- Feed URL: paste the Web Feed URL you copied from your Growave admin → Integrations → Klaviyo.
- Request method: Select GET.
- Content type: Select JSON.

5. Click Add web feed. Klaviyo will validate your feed. If successful, it will appear in your Web feeds list and can be previewed.

Insert reviews into abandoned cart emails

Once the Web Feed is active, you can insert reviews directly into your abandoned cart flow.

In Klaviyo admin, open your abandoned cart flow or create a new one.
Click Edit in the existing email action or add a new one.
Add a Text block, go to the Source code section.
Replace the example code with the HTML snippet below and click Apply. Save and launch your flow.

✅ Tip

You can control how much content displays in your emails by adjusting the values at the top of the code block:

max_product_count=5 → maximum number of products shown (default is 5).
max_review_count=3 → maximum number of reviews shown per product (default is 3).

FAQs

What feed name should I use in Klaviyo?

The feed name must be set to GROWAVE_PRODUCT_REVIEWS. Our HTML snippet references feeds.GROWAVE_PRODUCT_REVIEWS.items, so using any other name will break the integration.

Do I need to change the request method or content type?

No. Keep Klaviyo’s default settings: Request method = GET and Content type = JSON. Changing these will prevent the feed from working.

Where should I paste the HTML code in Klaviyo?

Use a Text block in Source code mode. If you paste the snippet into an HTML block, it may not render correctly.

How many products and reviews are displayed by default?

The snippet is set to display up to 5 products and up to 3 reviews per product. You can adjust these limits to the lower end by editing the values for max_product_count and max_review_count at the top of the code.

What happens if a product has no 5-star reviews?

The review block for that product will be hidden automatically, so your email layout remains clean.

Do I need to enable abandoned cart tracking in Growave?

No. If you have already set up the relevant Klaviyo flow, it will track abandoned carts automatically. Growave only provides the product review data via the Web Feed.
