Thank you for your replies.
It's possibly just that Kevin, that using queryParameter allows for more fine grained detail.
But if anyone has a good reason to use one over the other, please illustrate, I'm still interested to learn why.
I can't seem to edit my original post (topic starter), likely because it's too long ago, but to elaborate on my original question.
I still don't understand the difference, and when to use one over the other.
I don't mean the difference between a query string and a query parameter, because that is already very clear to me. I am referring to the keys
queryString, one of which may be defined for the method property (such as get or post) of a resource. When to use the
queryParameter key, and when to use the
queryString key instead?
