Documentation looks great and seems to be a solid build but there’s one issue that would need to be addressed before being approved fully.
You have HttpClient in a using statement which is bad practice and can possibly lead to issues. Please refer to HttpClient and you for an explanation on why it’s a bad practice and a good way to use a HttpClient and properly Dispose of it.
After that is addressed I see no issues with moving this to approved.
Only other thing I saw was your use of fully capitalized variables where it’s good practice to use camelCase variables in C#. However, Nate I believe has addressed it to where variable cases aren’t an issue and it just comes down to good coding practices. I only mention this if you are concerned at all about good practices and as more of an informational point out. Being that it shouldn’t be an issue in SB it wouldn’t hinder it from approval either way.
