Zoom API JWT Tokens deprecation and replacement

[PowershellNinja]

As stated in https://marketplace.zoom.us/docs/guides/build/jwt-app/jwt-faq/, Zoom has deprecated JWT tokens and is going to completely remove them by June 2023, the replacement is called OAuth apps.
Are there any plans to build OAuth-App based authentication into this module?

So I didn't investigate a lot, but on first sight it seems, that a new function is needed. New-ZoomOAuthApiToken or something like that. Which replaces New-ZoomApiToken. Also New-ZoomHeaders needs some code change to support New-ZoomOAuthApiToken.

Are my assumptions correct?

I already managed to create a Server-to-Server OAuth app, request the token and list all users, without the PSZoom Module.
Trying now to figure out how to integrate it.

If you like, share your code, and if I have some time I can look at integrating it. Otherwise, if you're comfortable forking the project and making a pull request, that works for me. Thanks for bringing this to my attention.

Here's what I've got. Currently no error handling of any kind.

function New-ZoomOAuthApiToken {

    <#
    .SYNOPSIS
    Retrieves the Zoom OAuth API token
    .DESCRIPTION
    Retrieves the Zoom OAuth API token

    .PARAMETER ClientID
    Client ID of the Zoom App

    .PARAMETER ClientSecret
    Client Secret of the Zoom App

    .PARAMETER AccountID
    Account ID of the Zoom App
    
    .OUTPUTS
    Zoom API Response

    .NOTES
    Version:        1.0
    Author:         noaboa97
    Creation Date:  20.07.2022
    Purpose/Change: Initial function development
  
    .EXAMPLE
    $clientid = "YourClientID"
    $clientsecret = "YourClientSecret"
    $AccountID = "YourAccountID"

    Get-XMCToken -ClientID $clientid -ClientSecret $clientsecret -AccountID $AccountID

    .EXAMPLE
    $token = Get-XMCToken -ClientID $clientid -ClientSecret $clientsecret -AccountID $AccountID
    #>

    [CmdletBinding()]
    param (
        [Parameter(valuefrompipeline = $true, mandatory = $true, HelpMessage = "Enter Zoom App Client ID:", Position = 0)]
        [String]
        $ClientID,

        [Parameter(valuefrompipeline = $true, mandatory = $true, HelpMessage = "Enter Zoom App Client Secret:", Position = 1)]
        [String]
        $ClientSecret,

        [Parameter(valuefrompipeline = $true, mandatory = $true, HelpMessage = "Enter Zoom App Account ID", Position = 2)]
        [String]
        $AccountID
    )


    $Uri = "https://zoom.us/oauth/token?grant_type=account_credentials&account_id={0}" -f $AccountID

    #Encoding of the client data
    $IDSecret = $ClientID + ":" + $ClientSecret 
    $EncodedIDSecret = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($IDSecret))

    $headers = @{
        "Authorization" = "Basic $EncodedIDSecret"  
    }
            
    # Maybe add some error handling
    $response = Invoke-WebRequest -uri $Uri -headers $headers -Method Post 

    return $response

}

Have a look if you have time, in the mean time I will check how I can integrate and keep you up to date.

#71 I didn't really like how I handled retrieving the token from Zoom, so I used this as an opportunity to revamp things. I pushed a new version to PowerShell Gallery, dropping support for JWT while introducing a new cmdlet named Connect-PSZoom.
