When setting webhooks, it\'s saying a Secure URL
is required.
I did not try programming with the Messenger Bot yet, but i know how webhooks work, so here´s the problem:
Webhooks are basically URLs that are called from Facebook. I assume you are trying to set up webhooks with localhost, but how would Facebook access localhost? It only exists on your own computer. Also, the error message is very clear, you need SSL for the webhook URL. There are "self signed certificates" for localhost, but it does not help you in that case - again, Facebook needs to be able to call that webhook callback URL.
