Note

You can't change the queue type after you create it and you can't convert an existing standard queue into a FIFO queue. You must either create a new FIFO queue for your application or delete your existing standard queue and recreate it as a FIFO queue. For more information, see Moving From a Standard Queue to a FIFO Queue in the Amazon SQS Developer Guide .

If you don't provide a value for an attribute, the queue is created with the default value for the attribute.

If you delete a queue, you must wait at least 60 seconds before creating a queue with the same name.

To successfully create a new queue, you must provide a queue name that adheres to the limits related to queues and is unique within the scope of your queues.

Note

After you create a queue, you must wait at least one second after the queue is created to be able to use the queue.

To retrieve the URL of a queue, use the GetQueueUrl action. This action only requires the QueueName parameter.

When creating queues, keep the following points in mind:

If you specify the name of an existing queue and provide the exact same names and values for all its attributes, the CreateQueue action will return the URL of the existing queue instead of creating a new one.

If you attempt to create a queue with a name that already exists but with different attribute names or values, the CreateQueue action will return an error. This ensures that existing queues are not inadvertently altered.

Note

Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide .

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters .

The request accepts the following data in JSON format.

A map of attributes with their corresponding values.

The following lists the names, descriptions, and values of the special request parameters that the CreateQueue action uses:


   DelaySeconds

– The length of time, in seconds, for which the delivery of all messages in the queue is delayed. Valid values: An integer from 0 to 900 seconds (15 minutes). Default: 0.


   MaximumMessageSize

– The limit of how many bytes a message can contain before Amazon SQS rejects it. Valid values: An integer from 1,024 bytes (1 KiB) to 262,144 bytes (256 KiB). Default: 262,144 (256 KiB).


   MessageRetentionPeriod

– The length of time, in seconds, for which Amazon SQS retains a message. Valid values: An integer from 60 seconds (1 minute) to 1,209,600 seconds (14 days). Default: 345,600 (4 days). When you change a queue's attributes, the change can take up to 60 seconds for most of the attributes to propagate throughout the Amazon SQS system. Changes made to the


   MessageRetentionPeriod

attribute can take up to 15 minutes and will impact existing messages in the queue potentially causing them to be expired and deleted if the


   MessageRetentionPeriod

is reduced below the age of existing messages.


   Policy

– The queue's policy. A valid AWS policy. For more information about policy structure, see Overview of AWS IAM Policies in the IAM User Guide .


   ReceiveMessageWaitTimeSeconds

– The length of time, in seconds, for which a


   
    ReceiveMessage

action waits for a message to arrive. Valid values: An integer from 0 to 20 (seconds). Default: 0.


   VisibilityTimeout

– The visibility timeout for the queue, in seconds. Valid values: An integer from 0 to 43,200 (12 hours). Default: 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon SQS Developer Guide .

The following attributes apply only to dead-letter queues: RedrivePolicy – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. The parameters are as follows:


   deadLetterTargetArn

– The Amazon Resource Name (ARN) of the dead-letter queue to which Amazon SQS moves messages after the value of


   maxReceiveCount

is exceeded.


   maxReceiveCount

– The number of times a message is delivered to the source queue before being moved to the dead-letter queue. Default: 10. When the


   ReceiveCount

for a message exceeds the


   maxReceiveCount

for a queue, Amazon SQS moves the message to the dead-letter-queue.


   RedriveAllowPolicy

– The string that includes the parameters for the permissions for the dead-letter queue redrive permission and which source queues can specify dead-letter queues as a JSON object. The parameters are as follows:


   allowAll

– (Default) Any source queues in this AWS account in the same Region can specify this queue as the dead-letter queue.


   denyAll

– No source queues can specify this queue as the dead-letter queue.


   byQueue

– Only queues specified by the


   sourceQueueArns

parameter can specify this queue as the dead-letter queue.


   sourceQueueArns

– The Amazon Resource Names (ARN)s of the source queues that can specify this queue as the dead-letter queue and redrive messages. You can specify this parameter only when the


   redrivePermission

parameter is set to


   byQueue

. You can specify up to 10 source queue ARNs. To allow more than 10 source queues to specify dead-letter queues, set the


   redrivePermission

parameter to


   allowAll

Note

The dead-letter queue of a FIFO queue must also be a FIFO queue. Similarly, the dead-letter queue of a standard queue must also be a standard queue.

The following attributes apply only to server-side-encryption :


   KmsMasterKeyId

– The ID of an AWS managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms . While the alias of the AWS managed CMK for Amazon SQS is always


   alias/aws/sqs

, the alias of a custom CMK can, for example, be


   alias/
   
    MyAlias

. For more examples, see KeyId in the AWS Key Management Service API Reference .


   KmsDataKeyReusePeriodSeconds

– The length of time, in seconds, for which Amazon SQS can reuse a data key to encrypt or decrypt messages before calling AWS KMS again. An integer representing seconds, between 60 seconds (1 minute) and 86,400 seconds (24 hours). Default: 300 (5 minutes). A shorter time period provides better security but results in more calls to KMS which might incur charges after Free Tier. For more information, see How Does the Data Key Reuse Period Work?


   SqsManagedSseEnabled

– Enables server-side queue encryption using SQS owned encryption keys. Only one server-side encryption option is supported per queue (for example, SSE-KMS or SSE-SQS ).

The following attributes apply only to FIFO (first-in-first-out) queues :


   FifoQueue

– Designates a queue as FIFO. Valid values are


   true

and


   false

. If you don't specify the


   FifoQueue

attribute, Amazon SQS creates a standard queue. You can provide this attribute only during queue creation. You can't change it for an existing queue. When you set this attribute, you must also provide the


   MessageGroupId

for your messages explicitly.

For more information, see FIFO queue logic in the Amazon SQS Developer Guide .


   ContentBasedDeduplication

– Enables content-based deduplication. Valid values are


   true

and


   false

. For more information, see Exactly-once processing in the Amazon SQS Developer Guide . Note the following:

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

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 following attributes apply only to high throughput for FIFO queues :


   DeduplicationScope

– Specifies whether message deduplication occurs at the message group or queue level. Valid values are


   messageGroup

and


   queue


   FifoThroughputLimit

– Specifies whether the FIFO queue throughput quota applies to the entire queue or per message group. Valid values are


   perQueue

and


   perMessageGroupId

. The


   perMessageGroupId

value is allowed only when the value for


   DeduplicationScope


   messageGroup

To enable high throughput for FIFO queues, do the following:

Set FifoThroughputLimit to perMessageGroupId .

If you set these attributes to anything other than the values shown for enabling high throughput, normal throughput is in effect and deduplication occurs as specified.

For information on throughput quotas, see Quotas related to messages in the Amazon SQS Developer Guide .

Type: String to string map

Required: No

A queue name can have up to 80 characters.

Valid values: alphanumeric characters, hyphens ( - ), and underscores ( _ ).

A FIFO queue name must end with the .fifo suffix.

Queue URLs and names are case-sensitive.

Type: String

Required: Yes

Add cost allocation tags to the specified Amazon SQS queue. For an overview, see Tagging Your Amazon SQS Queues in the Amazon SQS Developer Guide .

When you use queue tags, keep the following guidelines in mind:

Adding more than 50 tags to a queue isn't recommended.

Tags don't have any semantic meaning. Amazon SQS interprets tags as character strings.

Tags are case-sensitive.

A new tag with a key identical to that of an existing tag overwrites the existing tag.

For a full list of tag restrictions, see Quotas related to queues in the Amazon SQS Developer Guide .

Note

To be able to tag a queue on creation, you must have the sqs:CreateQueue and sqs:TagQueue permissions.

Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a username in the Amazon SQS Developer Guide .

Type: String to string map

Required: No

Response Syntax

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

You must wait 60 seconds after deleting a queue before you can create another queue with the same name.

HTTP Status Code: 400

A queue with this name already exists. Amazon SQS returns this error only if the request includes attributes whose values differ from those of the existing queue.

HTTP Status Code: 400

Ensure that the request rate is within the Amazon SQS limits for sending messages. For more information, see Amazon SQS quotas in the Amazon SQS Developer Guide .

HTTP Status Code: 400

Examples

The following example query requests create a new queue named MyQueue . The structure of AUTHPARAMS depends on the signature of the API request. For more information, see Examples of Signed Signature Version 4 Requests in the AWS General Reference .
