create_queue(**kwargs)¶Creates a new standard or FIFO queue. You can pass one or more attributes in the request. Keep the following in mind:
FifoQueue attribute, Amazon SQS creates a standard queue.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 .
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 get the queue URL, use the GetQueueUrl action. GetQueueUrl requires only the QueueName parameter. be aware of existing queue names:
CreateQueue returns the queue URL for the existing queue.CreateQueue returns an error.Some actions take lists of parameters. These lists are specified using the param.n notation. Values of n are integers starting from 1. For example, a parameter list with two elements looks like this:
&AttributeName.1=first
&AttributeName.2=second
Note
Cross-account permissions don't apply to this action. For more information, see Grant cross-account permissions to a role and a user name in the Amazon SQS Developer Guide .

Request Syntax
queue = sqs.create_queue(
QueueName='string',
Attributes={
'string': 'string'
},
tags={
'string': 'string'
}
)
[REQUIRED]
The name of the new queue. The following limits apply to this name:
- ), and underscores ( _ )..fifo suffix.Queue URLs and names are case-sensitive.
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).Policy – The queue's policy. A valid Amazon Web Services policy. For more information about policy structure, see Overview of Amazon Web Services IAM Policies in the Amazon 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.RedrivePolicy – The string that includes the parameters for the dead-letter queue functionality of the source queue as a JSON object. For more information about the redrive policy and dead-letter queues, see Using Amazon SQS Dead-Letter Queues in the Amazon SQS Developer Guide .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. When the ReceiveCount for a message exceeds the maxReceiveCount for a queue, Amazon SQS moves the message to the dead-letter-queue.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.
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 server-side-encryption:
KmsMasterKeyId – The ID of an Amazon Web Services managed customer master key (CMK) for Amazon SQS or a custom CMK. For more information, see Key Terms. While the alias of the Amazon Web Services 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 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 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 (e.g. 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:MessageDeduplicationId .MessageDeduplicationId explicitly.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).MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error.ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.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.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 is messageGroup .To enable high throughput for FIFO queues, do the following:
DeduplicationScope to messageGroup .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 .
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:
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 user name in the Amazon SQS Developer Guide .
