mass-edits in Managed Cloud

You can do this kind of migration work by reverse-engineering the web service calls, whether from your web browser’s tools or from the Aurena developer console.

I wrote a working solution to your problem above here in PowerShell. It uses basic authentication against the IFSADMIN user. You can remove the Get-Projection function if you’d like.

$basic_username = 'IFSADMIN'
$basic_password = 'ifsadmin_password'
$hostname = 'ifs.example.com'

$credential_plaintext = "$($basic_username):$($basic_password)"
$credential_bytes = [System.Text.Encoding]::UTF8.GetBytes($credential_plaintext)
$credential_base64 = [Convert]::ToBase64String($credential_bytes)
$headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$headers.Add("Content-Type", "application/json")
$headers.Add("Authorization", "Basic $($credential_base64)")

Function Post-Projection {
   param($service_and_set, $body_hashtable)
   $uri = 'https://' + $global:hostname +
          '/main/ifsapplications/projection/v1/' + $service_and_set
   $headers_local = $global:headers
   $headers_local.Remove('If-Match') | Out-Null
   $body = $body_hashtable | ConvertTo-Json -Compress
   If (!$body) {
      $body = '{}'
   }
   $method = 'POST'
   $response =
      Invoke-RestMethod `
         -Uri $uri -Method $method -Headers $headers_local -Body $body
   $response
}

Function Get-Projection {
   param($service_and_set)
   $uri = 'https://' + $global:hostname +
          '/main/ifsapplications/projection/v1/' + $service_and_set
   $headers_local = $global:headers
   $headers_local.Remove('If-Match') | Out-Null
   $method = 'GET'
   $response =
      Invoke-RestMethod `
         -Uri $uri -Method $method -Headers $headers_local -Body $body
   $response
}

Function Grant-UserCompany {
   param($identity, $company)

   $response = Post-Projection `
      -service_and_set "UserHandling.svc/AddCompaniesAssistantVirtuals" `
      -body_hashtable @{'Identity'=$identity}
   $objkey = $response.objkey

   $response = Post-Projection `
      -service_and_set "UserHandling.svc/AddCompaniesAssistantVirtuals(Objkey='$($objkey)')/IfsApp.UserHandling.AddCompaniesAssistantVirtual_ApplyChanges" `
      -body_hashtable @{
         'Companies'="COMPANY=$($company)^IDENTITY=$($identity)^"}
   $response
}

Grant-UserCompany -identity 'JDOE1' -company '123'
Grant-UserCompany -identity 'JDOE2' -company '123'
Grant-UserCompany -identity 'JDOE3' -company '123'
