Issues with ActiveWoo [Woocommerce + Active Campaign integration

I have problem with two features of ActiveWoo plugin.

- The first: the webhook to create coupons from Active Campaign is not working, you can see how it works the plugin here: https://www.youtube.com/watch?v=KNQHLlnrWvI

- And second: Cart Recovery URL neither work.
