Hey @Cambo 

Integrating Wishlist King with Klaviyo for Shopify requires a few manual steps since Wishlist King doesn’t have a native integration with Klaviyo. However, you can still track wishlist activities and use the data in Klaviyo by following these steps: 

Webhook Integration with Wishlist King

• Wishlist King allows you to send data to external platforms using webhooks. You can capture these events (e.g., when someone adds an item to their wishlist) and pass them to Klaviyo.

Here’s how you can set up the webhook in Wishlist King:

• Go to the Wishlist King app in Shopify.
• Navigate to the Settings and find the option for Webhooks.
• Add a webhook URL that will send the wishlist activity data to Klaviyo.
• The webhook URL can be structured to call a specific endpoint in Klaviyo. For example, you can use Klaviyo's Track API to send events like "Added to Wishlist" or "Removed from Wishlist."

You will need to work with a developer to set up this part as it requires creating a server-side function that captures the webhook from Wishlist King and sends the data to Klaviyo using the Track API.
