After activating the product i checked to see if the plans and limits were correctly set.
There is saw that the Smart AI calls are limited, did not see this restriction mentioned on the page where i purchased.

As i am used to monthly renewals, i expected the wrong thing, my fault. Good to see that you can buy extra credits when needed.

Also the Webhooks available are limited... am not sure if i need to upgrade already now to secure extra webhooks, or if i can purchase extra later on as well
