The function then uses the AttachmentInfo objects to get any attachment ids and then the attachments are downloaded and returned. .INPUTS Either Nothing, Account, Ticket, Opportunity or Project .OUTPUTS Autotask attachments .EXAMPLE Get-AtwsAttachment -Id 0 Returns the attachment with Id 0, if any. .EXAMPLE Get-AtwsAttachmentInfo -AccountId 0 Returns any attachments connected to the Account with id 0. .EXAMPLE Get-AtwsAttachmentInfo -OpportunityId 0 Returns any attachments connected to an Opportunity with id 0. .EXAMPLE Get-AtwsAttachmentInfo -ProjectId 0 Returns any attachments connected to a Project with id 0. .EXAMPLE Get-AtwsAttachmentInfo -TicketId 0 Returns any attachments connected to a Ticket with id 0. .EXAMPLE $Ticket | Get-AtwsAttachmentInfo Returns any attachments connected to the Ticket passed through the pipeline. Also works for Opportunities, Accounts and Projects. .NOTE Strongly related to Get-AtwsAttachmentInfo #> [CmdLetBinding(SupportsShouldProcess = $true, DefaultParameterSetName = 'By_id', ConfirmImpact = 'None')] Param ( # An object that will be modified by any parameters and updated in Autotask [Parameter( Mandatory = $true, ParameterSetName = 'Input_Object', ValueFromPipeline = $true )] [ValidateNotNullOrEmpty()] [ValidateScript( { # InputObject must be one of these four types if( $_[0].GetType().Name -in 'Account', 'Ticket', 'Opportunity', 'Project' ){ return $true } })] # [PSObject[]] $InputObject, # Attachment ID [Parameter( Mandatory = $true, ParameterSetName = 'By_id' )] [ValidateNotNullOrEmpty()] [long[]] $id, # Account ID [Parameter( Mandatory = $true, ParameterSetName = 'Account' )] [ValidateScript( { if ( -Not (Get-AtwsAccount -id $_) ) { throw "Account does not exist" } return $true })] [long[]] $AccountID, # Opportunity ID [Parameter( Mandatory = $true, ParameterSetName = 'Opportunity' )] [ValidateScript( { if ( -Not (Get-AtwsOpportunity -id $_) ) { throw "Opportunity does not exist" } return $true })] [long[]] $OpportunityID, # Project ID [Parameter( Mandatory = $true, ParameterSetName = 'Project' )] [ValidateScript( { if ( -Not (Get-AtwsProject -id $_) ) { throw "Project does not exist" } return $true })] [long[]] $ProjectID, # Ticket ID [Parameter( Mandatory = $true, ParameterSetName = 'Task Or Ticket' )] [ValidateScript( { if ( -Not (Get-AtwsTicket -id $_) ) { throw "Ticket does not exist" } return $true })] [long[]] $TicketID ) begin { if (-not($Script:Atws.integrationsValue)) { # Not connected.
