Hi everyone, I would like to create and publish a simple SuiteApp, which will include a RESTlet script. I would appreciate it if someone could share a tutorial or any resources that would be helpful in achieving this. Thank you!

Do you have all the pre-requisites in place to allow you to publish a SuiteApp?

Yes, I think, What are these could you please share checklist

I don't have one, if you haven't done anything so far though there's steps to follow to be able to publish a SuiteApp, you cannot just create a SuiteApp AFAIK.
