How to create git remote repository using script RHEL 7 - git-remote

Question

I apologize if this question has been asked but I could not find any answers when I did a search.
I am trying to create a GIT remote repository that is being hosted on our server (123.123.com) instead of gitlab.com using a script. I have found really great scripts that connected via https that I was able to tweak and get it to work in my vm # home but that configuration is user to gitlab.com.
I don't know how to tweak the script to replace things like "content-type json" .... or find the API for the server. So, I think ideally the below script written by ckalima is what I would like to use but I'm a noob to GIT and definitely scripting on a whole. https://gist.github.com/ckalima/1364886
I replaced all the variables and it does not work. In the end, it says it creates the repo but it really doesn't. Sorry for the long post, thanks in advance. Joybells
