Powershell script doesn't recognize query parameters

Question

I'm trying the following:

 $Result = Invoke-RestMethod "https://graph.microsoft.com/v1.0/groups?$top=1"

But the ?$top=1 part just doesn't work. I know it should, because when testing in Microsoft Graph explorer, it does!..

So WTH am I doing wrong?!

Did you try to use single quotes? $Result = Invoke-RestMethod 'https://graph.microsoft.com/v1.0/groups?$top=1', see help about_quoting_rules — Ocaso Protal

That worked. Crazy, and absolutely ridiculous. I can only imagine how many people have buggy scripts and a headache because of this. Either enforce single quotes, or give me the same result. — Erechtheus

You have to use single quotes instead of double quotes:

$Result = Invoke-RestMethod 'https://graph.microsoft.com/v1.0/groups?$top=1'

The reason is that with dobule qoutes Powershell tries to evaluate the $top expression, see: help about_quoting_rules

In Powershell, if a string is enclosed in double-quotes then expressions and special characters inside will be evaluated and expanded. The $ sign in your $top expression is being evaluated and the value of the $top variable is being inserted in there.

This is super useful for a lot of reasons, but if you don't want it to happen, then single quotes will work (as others have mentioned). Or you can escape the dollar sign using the backtick operator. E.g.

$Result = Invoke-RestMethod "https://graph.microsoft.com/v1.0/groups?`$top=1"
