Where do I need put access key it in server.js?
I don't need use heroku has limited hours. Running of time I can't get it webhook. Please I need help with setup my server.
Actually I hate other website hosting and limited rate I wouldn't recommend use other website. I can use domain or my ip address public if it is test with server.
