Synopsis

Calls the AWS Support DescribeCommunications API operation.

Syntax

Get-ASACommunication
-CaseId <String>
-AfterTime <String>
-BeforeTime <String>
-DryRun <Boolean>
-MaxResult <Int32>
-NextToken <String>
-Select <String>
-NoAutoIteration <SwitchParameter>
-ClientConfig <AmazonAWSSupportConfig>

Description

Returns communications and attachments for one or more support cases. Use the afterTime and beforeTime parameters to filter by date. You can use the caseId parameter to restrict the results to a specific case. Case data is available for 24 months after creation. If a case was created more than 24 months ago, a request for data might cause an error. You can use the maxResults and nextToken parameters to control the pagination of the results. Set maxResults to the number of cases that you want to display on each page, and use nextToken to specify the resumption of pagination.
  • You must have an Amazon Web Services Business Support+, Amazon Web Services Enterprise Support, or Amazon Web Services Unified Operations plan to use the Amazon Web Services Support API. If you're in an Amazon Web Services Region that doesn't offer one of these Amazon Web Services Support plans, or if you haven't transitioned to one of these plans, you can use the Amazon Web Services Support API with a Business, Enterprise On-Ramp, or Enterprise Support plan.
  • If you call the Amazon Web Services Support API from an account that doesn't have an Amazon Web Services Business Support+, Amazon Web Services Enterprise Support, or Amazon Web Services Unified Operations plan, the SubscriptionRequiredException error message appears. For information about changing your support plan, see Amazon Web Services Support.
Each Communication returned by this operation includes attachment information in two fields:
  • attachmentSet: returns only attachments that are 5 MB or smaller. Attachments larger than 5 MB are not included in this field.
  • attachments: returns all attachments regardless of size.
Amazon Web Services recommends that you use the attachments field and download each attachment with GetAttachmentDownloadLink, which supports attachments of any size. The attachmentSet field and DescribeAttachment return only attachments that are 5 MB or smaller.

This cmdlet automatically pages all available results to the pipeline - parameters related to iteration are only needed if you want to manually control the paginated output. To disable autopagination, use -NoAutoIteration.

Note: For scripts written against earlier versions of this module this cmdlet can also be invoked with the alias, Get-ASACommunications.

Parameters

-AfterTime <String>
The start date for a filtered date search on support case communications. Case communications are available for 24 months after creation.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-BeforeTime <String>
The end date for a filtered date search on support case communications. Case communications are available for 24 months after creation.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-CaseId <String>
The support case ID requested or returned in the call. The case ID is an alphanumeric string formatted as shown in this example: case-12345678910-exen-2025-c4c1d2bf33c5cf47
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-ClientConfig <AmazonAWSSupportConfig>
Amazon.PowerShell.Cmdlets.ASA.AmazonAWSSupportClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-DryRun <Boolean>
Specifies whether to validate the request without actually returning communications. When set to true, the request is validated but no communications are returned, and the operation returns a DryRunOperationException. When omitted or set to false, the request runs normally.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-MaxResult <Int32>
The maximum number of results to return before paginating.
Note: In AWSPowerShell and AWSPowerShell.NetCore this parameter is used to limit the total number of items returned by the cmdlet.
In AWS.Tools this parameter is simply passed to the service to specify how many items should be returned by each service call.
Pipe the output of this cmdlet into Select-Object -First to terminate retrieving data pages early and control the number of items returned.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesMaxItems, MaxResults
-NextToken <String>
A resumption point for pagination.
Note: This parameter is only used if you are manually controlling output pagination of the service API call.
'NextToken' is only returned by the cmdlet when '-Select *' is specified. In order to manually control output pagination, set '-NextToken' to null for the first call then set the 'NextToken' using the same property output from the previous call for subsequent calls.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NoAutoIteration <SwitchParameter>
By default the cmdlet will auto-iterate and retrieve all results to the pipeline by performing multiple service calls. If set, the cmdlet will retrieve only the next 'page' of results using the value of NextToken as the start point.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Communications'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.AWSSupport.Model.DescribeCommunicationsResponse). Specifying the name of a property of type Amazon.AWSSupport.Model.DescribeCommunicationsResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named

AliasesAK
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile.

-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
