Delivers a message to the specified queue.
A message can include only XML, JSON, and unformatted text. The following Unicode characters are allowed. For more information, see the W3C specification for characters .
#x9
|#xA
|#xD
|#x20
to#xD7FF
|#xE000
to#xFFFD
|#x10000
to#x10FFFF
Amazon SQS does not throw an exception or completely reject the message if it contains invalid characters. Instead, it replaces those invalid characters with U+FFFD
before storing the message in the queue, as long as the message body contains at least one valid character.

--delay-seconds
(integer)
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.Note
When you setFifoQueue
, you can't setDelaySeconds
per message. You can set this parameter only on a queue level.
--message-attributes
(map)
Each message attribute consists of a
Name
,Type
, andValue
. For more information, see Amazon SQS message attributes in the Amazon SQS Developer Guide .key -> (string)

Name
,Type
, andValue
.Warning
- Currently, the only supported message system attribute is
AWSTraceHeader
. Its type must beString
and its value must be a correctly formatted X-Ray trace header string.- The size of a message system attribute doesn't count towards the total size of a message.

--message-deduplication-id
(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 sameMessageDeduplicationId
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 enableContentBasedDeduplication
for your queue, Amazon SQS uses a SHA-256 hash to generate theMessageDeduplicationId
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 haveContentBasedDeduplication
set, the action fails with an error.- If the queue has
ContentBasedDeduplication
set, yourMessageDeduplicationId
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 aMessageDeduplicationId
that is the same as the one generated for the firstMessageDeduplicationId
, the two messages are treated as duplicates and only one copy of the message is delivered.Note
The
MessageDeduplicationId
is available to the consumer 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.Amazon SQS continues to keep track of the message deduplication ID even after the message is received and deleted.
The maximum 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 SQS Developer Guide .
--message-group-id
(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 consumers 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 aMessageGroupId
, the action fails.ReceiveMessage
might return messages with multipleMessageGroupId
values. For eachMessageGroupId
, the messages are sorted by time sent. The caller can't specify aMessageGroupId
.The maximum length of
MessageGroupId
is 128 characters. Valid values: alphanumeric characters and punctuation(!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~)
.For best practices of using
MessageGroupId
, see Using the MessageGroupId Property in the Amazon SQS Developer Guide .Warning
MessageGroupId
is required for FIFO queues. You can't use it for Standard queues.
--cli-input-json
(string)
Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
--debug
(boolean)
Turn on debug logging.
--endpoint-url
(string)
Override command's default URL with the given URL.
--no-verify-ssl
(boolean)
By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.
--no-paginate
(boolean)
Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.
--output
(string)
The formatting style for command output.
--query
(string)
A JMESPath query to use in filtering the response data.
--profile
(string)
Use a specific profile from your credential file.
--region
(string)
The region to use. Overrides config/env settings.
--version
(string)
Display the version of this tool.
--color
(string)
Turn on/off color output.
--no-sign-request
(boolean)
Do not sign requests. Credentials will not be loaded if this argument is provided.
--ca-bundle
(string)
The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.
--cli-read-timeout
(int)
The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.
--cli-connect-timeout
(int)
The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.
To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.
Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .
To send a message
This example sends a message with the specified message body, delay period, and message attributes, to the specified queue.
Command:
aws sqs send-message --queue-url https://sqs.us-east-1.amazonaws.com/80398EXAMPLE/MyQueue --message-body "Information about the largest city in Any Region." --delay-seconds 10 --message-attributes file://send-message.json
