I am having problems with Google Drive API - Push Notifications. I did everything as specified in the documentation. Everything works perfectly to the step where I should receive "sync" notification to my endpoint. I have secure endpoint (https), certificate by letsencrypt (certbot), I have registerd and verified my domain. I suspect the problem is basic authentication on my endpoint. When I created a channel I specified my endpoint like this:
https://username:password@mydomain.com/endpoint
Does this not work? Is there another way to specify that I have basic auth on my side?
EDIT: I tested it without basic auth (I commented out basic auth in .htaccess file) and I received sync message. So basic auth is the main problem.
