github service hook and basic authentication

github service hook and basic authentication

I'm trying to figure out how to secure a webhook reciever for a github
service hook.
In the github manual pages, when you look in the section on what IP
addresses github hooks will come from, it has this warning:
"We highly recommend that you don't white list IPs for Service Hooks.
Instead, setup HTTPS and basic authentication to verify incoming
requests."
https://help.github.com/articles/what-ip-addresses-does-github-use-that-i-should-whitelist#service-hook-ip-addresses
In the documentation on post receive hooks I don't see any way to set up
basic authentication.
How can I use basic authentication with github post-recieve/service/web
hook that notifies me of a commit to a repository?
