Synopsis

Invokes the SendMessage operation against Amazon Simple Queue Service.

Syntax

Send-SQSMessage
-QueueUrl <String>
-MessageBody <String>
-DelayInSeconds <Int32>
-MessageAttribute <Hashtable>
-MessageDeduplicationId <String>
-MessageGroupId <String>
-Force <SwitchParameter>

Description

Delivers a message to the specified queue. A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed: #x9 | #xA | #xD | #x20 to #xD7FF | #xE000 to #xFFFD | #x10000 to #x10FFFF Any characters not included in this list will be rejected. For more information, see the W3C specification for characters.

Parameters

-DelayInSeconds <Int32>
The length of time, in seconds, for which to delay a specific message. Valid values: 0 to 900. Maximum: 15 minutes. Messages with a positive DelaySeconds value become available for processing after the delay period is finished. If you don't specify a value, the default value for the queue applies. When you set FifoQueue, you can't set DelaySeconds per message. You can set this parameter only on a queue level.
Required?False
Position?3
Accept pipeline input?False
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-MessageAttribute <Hashtable>
Each message attribute consists of a Name, Type, and Value. For more information, see Message Attribute Items and Validation in the Amazon SQS Developer Guide.
Required?False
Position?Named
Accept pipeline input?False
-MessageBody <String>
The message to send. The maximum string size is 256 KB.A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed:#x9 | #xA | #xD | #x20 to #xD7FF | #xE000 to #xFFFD | #x10000 to #x10FFFFAny characters not included in this list will be rejected. For more information, see the W3C specification for characters.
Required?False
Position?2
Accept pipeline input?False
-MessageDeduplicationId <String>
This parameter applies only to FIFO (first-in-first-out) queues.The token used for deduplication of sent messages. If a message with a particular MessageDeduplicationId is sent successfully, any messages sent with the same MessageDeduplicationId are accepted successfully but aren't delivered during the 5-minute deduplication interval. For more information, see Exactly-Once Processing in the Amazon SQS Developer Guide.
  • Every message must have a unique MessageDeduplicationId,
    • You may provide a MessageDeduplicationId explicitly.
    • If you aren't able to provide a MessageDeduplicationId and you enable ContentBasedDeduplication for your queue, Amazon SQS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).
    • If you don't provide a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error.
    • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.
  • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.
  • If you send one message with ContentBasedDeduplication enabled and then another message with a MessageDeduplicationId that is the same as the one generated for the first MessageDeduplicationId, the two messages are treated as duplicates and only one copy of the message is delivered.
The MessageDeduplicationId is available to the recipient of the message (this can be useful for troubleshooting delivery issues).If a message is sent successfully but the acknowledgement is lost and the message is resent with the same MessageDeduplicationId after the deduplication interval, Amazon SQS can't detect duplicate messages.The length of MessageDeduplicationId is 128 characters. MessageDeduplicationId can contain alphanumeric characters (a-z, A-Z, 0-9) and punctuation (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~).For best practices of using MessageDeduplicationId, see Using the MessageDeduplicationId Property in the Amazon Simple Queue Service Developer Guide.
Required?False
Position?Named
Accept pipeline input?False
-MessageGroupId <String>
This parameter applies only to FIFO (first-in-first-out) queues.The tag that specifies that a message belongs to a specific message group. Messages that belong to the same message group are processed in a FIFO manner (however, messages in different message groups might be processed out of order). To interleave multiple ordered streams within a single queue, use MessageGroupId values (for example, session data for multiple users). In this scenario, multiple readers can process the queue, but the session data of each user is processed in a FIFO fashion.
  • You must associate a non-empty MessageGroupId with a message. If you don't provide a MessageGroupId, the action fails.
  • ReceiveMessage might return messages with multiple MessageGroupId values. For each MessageGroupId, the messages are sorted by time sent. The caller can't specify a MessageGroupId.
The length of MessageGroupId is 128 characters. Valid values are alphanumeric characters and punctuation (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~).For best practices of using MessageGroupId, see Using the MessageGroupId Property in the Amazon Simple Queue Service Developer Guide.MessageGroupId is required for FIFO queues. You can't use it for Standard queues.
Required?False
Position?Named
Accept pipeline input?False
-QueueUrl <String>
The URL of the Amazon SQS queue to which a message is sent.Queue URLs are case-sensitive.
Required?False
Position?1
Accept pipeline input?True (ByValue, 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
Accept pipeline input? False
-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? False
-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. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

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
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-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? False

Inputs

You can pipe a String object to this cmdlet for the QueueUrl parameter.
