Powershell API request with cookies

Question

I am trying to make an API request in Powershell.

The curl command that works:

curl -k -v -X GET -H "Cookie: customer=<valueA>;JSESSIONID=<ValueB>" -H "Accept: application/json" https://someurl.net/path/path

I Tried:

$session = New-Object Microsoft.Powershell.Commands.WebRequestSession
$cookie = New-Object System.Net.Cookie
$cookie2 = New-Object System.Net.Cookie

$cookie.Name = "customer"
$cookie.Value = "<valueA>"
$cookie.Domain = "https://someurl.net"

$cookie2.Name = "JSESSIONID"
$cookie2.Value = "<valueB>"
$cookie2.Domain = "https://someurl.net"

$session.Cookies.Add($cookie, $cookie2);

Invoke-WebRequest -Uri "https://someurl.net/path/path" -Method Get -WebSession $session -Headers  @{"accept"="application/json"}

This should return a json payload. Any help is appreciated.

Instead of headers, use -ContentType 'application\json'. Are your domains valid? — Maximilian Burszley

Changing the content type didn't seem to help. I'm using the domain of the web site that I am trying to access. — RMichalowski

are you getting an error message or just a null return? if your getting a weird object back Invoke-RestMethod might be worth a try — Mike Garuccio

Here might be the problem:

$session.Cookies.Add($cookie, $cookie2);

According to definition:

PS C:\> $session.Cookies.Add

OverloadDefinitions
-------------------
void Add(System.Net.Cookie cookie)
void Add(System.Net.CookieCollection cookies)
void Add(uri uri, System.Net.Cookie cookie)
void Add(uri uri, System.Net.CookieCollection cookies)

You should change it to:

$session.Cookies.Add($cookie);
$session.Cookies.Add($cookie2);
