We are getting emails from Klaviyo saying the API we are using is deprecated and about to be discontinued. Can you update the API versions this plugin is using? Call to /client/events in wck-added-to-cart.php (hooks into add to cart action) The revision version in wck-added-to-cart.php is set to 2023-08-15 and should be updated to 2025-01-15 Calls to both /client/events and /client/profiles in wck-started-checkout.js Calls to both in their blocks/build/events.js which is probably built from the other Thanks for reaching out @downstairsdev . The latest version of Klaviyo’s plugin uses revision 2025-04-15. Going forward the plugin will get revision updates twice a year.
