Powershell Invoke-WebRequest [Error happened while processing request]

Question

I am working on a project to automate creating AD users, creating folders in the different departments/sections for the users, also send password automatically when AD user is created to their cellphones & startup package in the user company mail.

I am having a problem doing this in PowerShell, this works great in Python (my main language). I get this odd error when trying to process my request in powershell.

Code:

$url = "hiding_this_for_obvious_reasons" # Request URL

$nummer = Read-Host("Skriv inn mobil nummer: ")
$tekst = Read-Host("Skriv inn melding: ")

#Request Payload information
$JSON = @'
{
            "content": "$tekst",
            "senderNumber": "SSB",
            "targetNumbersAsDelimitedString": "47$nummer",
            "sendDate": null,
            "status": {"id": "5"},
            "numberOfTargetNumbers": null,
            "numberOfInvalidNumbers": ""
}
'@

Invoke-WebRequest -Uri $url -Method Post -Body $JSON -ContentType "application/json"

The error message as follows:

Invoke-WebRequest : Error happened while processing request

It looks like you're trying to use variables but inside single quotes. It needs to be double quotes for the variables to be expanded.

Try this:

$JSON = @"
{
            "content": "$tekst",
            "senderNumber": "SSB",
            "targetNumbersAsDelimitedString": "47$nummer",
            "sendDate": null,
            "status": {"id": "5"},
            "numberOfTargetNumbers": null,
            "numberOfInvalidNumbers": ""
}
