One of the usecases of Go is to create CLI tools for developers to ease their work. Often it involves creating/modifying resources or retrieving information from cloud services. In this post we’re going to setup device flow authentication against AzureAD in Go.

If you are sending web requests with Powershell you will notice that if your requests fails, that is if it returns any status code other than 2xx, it will thrown an error. Now, how do get the details of the failed request?

Today I went back to some Powershell scripting with the Az module and it frustrated me that I wasn’t easily able to know what properties Get-AzADGroup (or any of the other Az cmdlets) returned to me without actually invoking the cmdlet. E.g I dont want to invoke New-AzADGroup just to be able to see what properties it will give me so I can use that in my script. Previously I’ve relied on IntelliSens in my editor, but it often fails, so I sought out to find a more manual solution (who would have thought..).

Most times when working with API’s there some kind of documentation on how to iteract with it. Working with Azure SDK for Go is a different story. There’s almost no documentation (except the code itself). At my current job we use Azure a lot and a big part of that is Azure Key Vault. For my latest project I had to fetch some secrets from Key Vault to use in a CLI application, so I had to start digging into the source code to find how to interact with it.

Additional comments and Work notes is of type Journal List and therefor we can not get their value directly. So here’s how to interact with comments and work_notes.
