Powershell: Iterate through arrays for multiple variables - powershell

Question

I need some mega guidance on my script below. I need to be able to iterate through a csv file that stores tenantNames, app_id, client_secret for my script and wrap a big ForEach loop around it in order for my script to get said data for each tenant inside the CSV:
I'm struggling to visualize the order of the For loops to be able to pass $Tenant, $customer_client_id and $customer_client_secret.
Arrays might be excessive, but it's the most stable way I know to avoid formatting issues etc...
Any assistance or ideas would be super helpful
$master_file = 'C:\temp\apps.csv'
$array_tenant = #()
$array_customer_client_id = #()
$array_customer_client_secret = #()
Import-Csv $master_file | ForEach-Object {
$array_tenant += $_.tenant
$array_customer_client_id += $_.app_id
$array_customer_client_secret += $_.cs
}
$Tenant = ''
$customer_client_id = ''
$customer_client_secret = ''
$Body = #{
Grant_Type = "client_credentials"
Scope = "https://graph.microsoft.com/.default"
client_Id = $customer_client_id
Client_Secret = $customer_client_secret
}
$ConnectGraph = Invoke-RestMethod -Uri "https://login.microsoftonline.com/$Tenant/oauth2/v2.0/token" -Method POST -Body $Body
$Token = $ConnectGraph.access_token
$file = "C:\temp\$Tenant._users_with_licenses.csv"
$final_results = "C:\temp\$Tenant._results.csv"
$users_array = #()
$user_list = 'https://graph.microsoft.com/beta/users'
$users = Invoke-RestMethod -Headers #{Authorization = "Bearer $($Token)"} -ContentType 'application/json' -Uri $user_list -Method 'GET'
$users.value | Where-Object {$_.assignedLicenses -ne "null"} | Select-Object userPrincipalName | Export-Csv $file -NoTypeInformation
Import-Csv $file | ForEach-Object {
$users_array += $_.userPrincipalName
}
foreach ($item in $users_array) {
$auth_methods = "https://graph.microsoft.com/v1.0/users/$item/authentication/methods"
$get_auth_methods = Invoke-RestMethod -Headers #{Authorization = "Bearer $($Token)"} -ContentType 'application/json' -Uri $auth_methods -Method 'GET'
if (!$get_auth_methods.value) {$get_auth_methods | Export-Csv $final_results -Append -NoTypeInformation}
}

I am going on a whim here and guessing this is what you're after:
$masterFile = 'C:\temp\apps.csv'
Import-Csv -Path $masterFile |
ForEach-Object -Process {
$tenant = $_.tenant
$request = #{
Uri = "https://login.microsoftonline.com/$Tenant/oauth2/v2.0/token"
Method = "POST"
Body = #{
Grant_Type = "client_credentials"
Scope = "https://graph.microsoft.com/.default"
client_Id = $_.app_id
Client_Secret = $_.cs
}
}
$connectGraph = Invoke-RestMethod #request
$token = $connectGraph.access_token
$filePath = "C:\temp\$Tenant._users_with_licenses.csv"
$finalResults = "C:\temp\$Tenant._results.csv"
$userRequest = #{
Uri = 'https://graph.microsoft.com/beta/users'
Method = "GET"
Headers = #{
Authorization = "Bearer $token"
ContentType = "application/json"
}
}
$usersGet = Invoke-RestMethod #userRequest
$users = $users.value | Where-Object -Property "assignedLicenses" -NE "null" | Select-Object -ExpandProperty "userPrincipalName"
$users | Export-Csv -Path $filePath -NoTypeInformation -Force
foreach ($user in $users)
{
$finalRequest = #{
Uri = "https://graph.microsoft.com/v1.0/users/$user/authentication/methods"
ContentType = "application/json"
Method = "GET"
Headers = #{
Authorization = "Bearer $Token"
}
}
$getAuthMethod = Invoke-RestMethod #finalRequest
if (-not$getAuthMethod) {
$getAuthMethod | Export-Csv -Path $finalResults -Append -NoTypeInformation
}
}
}
Without really seeing what you expect, quite hard to understand what you currently have. Hopefully this gets you in the right direction! I also made use of splatting as this is a good scenario on when to use it.
