First you need to create class library for CoreApiBasicAuth endpoint (use as a help how to do this) Using this library (for example CoreApiBasicAuth.dll) you can connect to Atomia Automation Server. In following example I created powershell script to list Windows Websites for specific account. [Reflection.Assembly]::LoadFrom("c:\CoreApiBasicAuth.dll") $wsHttpBinding = new-object System.ServiceModel.BasicHttpBinding $wsHttpBinding.Security.Message.ClientCredentialType = [System.ServiceModel.BasicHttpMessageCredentialType]::UserName $wsHttpBinding.Security.Mode = [System.ServiceModel.BasicHttpSecurityMode]::TransportWithMessageCredential $endpoint = new-object System.ServiceModel.EndpointAddress(" $coreAPI = new-object CoreApiClient($wsHttpBinding, $endpoint) $coreAPI.ClientCredentials.UserName.set_UserName("Admin") $coreAPI.ClientCredentials.UserName.set_Password("Admin") $Acc = $coreAPI.GetAccount("123456") #find websites for this account $pageInfo = New-ObjectAtomia.Provisioning.Base.PagingInfo $strNames = @("CsWindowsWebsite") $pageInfo.PageSize = 10 $pageInfo.PageNumber = 0 $res = $coreAPI.FindServicesByNamesForAccount($Acc.AccountId, $strNames, [ref] $pageInfo) $sites = $res | ForEach-Object {$_.properties} | Where-Object {$_.Name -eq "Hostname"} | Select-Object propStringValue Write-Output $sites $coreAPI.Close()
