The URL of the callback uses a valid SSL Certificate and returns 200 SUCCESS. It works fine in production but I cannot test with my dev kit unless I can get the webhook set up in my sandbox developer account. I see similar questions in the community dating back for years with no resolution and I feel like clover has NO developer support but instead keeps redirecting everything to the "Community". I am extremely frustrated, I just need to test a webhook using my dev kit. How can I accomplish this???
