 * 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

 * Thanks for reaching out [@downstairsdev](https://wordpress.org/support/users/downstairsdev/).
   The latest version of Klaviyo’s plugin uses revision 2025-04-15. Going forward
   the plugin will get revision updates twice a year.
