Hi Martins,

the API documentation has quite a lot of mistakes and it has gaps as well.

All of the API reference documentation is embedded in the CloudStack
source code.

I think the best way to get developers to look at it is to submit a bug at

or submit a pull request on the source code in Github, for example
here is one that I did...

Subject: Re: Get information
Hello Phillip,

/isoid/ is working only when ISO image is attached to instance. It
contains information only about attached ISO.
But anyway this is a bit odd, when I need to call API requests, which
return error, to find is this instance from ISO or template.
So is this documentation and removed API feature, or something else?
Maybe some of developers can say comment this?
