Aftersell & Klaviyo Reviews Integration

This article explains how to set up the Aftersell and Klaviyo Reviews integration for the testimonials widget.

To use Klaviyo reviews in the Aftersell testimonials widget, you need to provide your Klaviyo private API key.

Setting up Klaviyo integration

1. In Klaviyo, navigate to your account settings
2. Go to Integrations > Developers > Manage API keys
3. Click Create Private API Key
   • You can name it “Aftersell API key”
   • Select read-only permissions
4. Copy the generated API key
5. Open the Aftersell app, then go to Settings > Product Reviews
6. Select Klaviyo from the review integrations list
7. Paste your private API key in the Klaviyo private API key field
8. Click Save changes

The integration is complete. You can now use Klaviyo reviews in your Flex Testimonials widget.

Syncing reviews

Aftersell imports reviews from Klaviyo and stores them so they can be displayed in the testimonials widget. The first import happens automatically within 24 hours, and then once a week after that.

To import reviews immediately:

1. Go to Settings > Product Reviews
2. Find the Klaviyo reviews section
3. Click Sync now

The sync status shows when reviews were last imported and when the next sync is available.
