API Reference (API Version 2012-11-05)

CreateQueue

Creates a new standard or FIFO queue. You can pass one or more attributes in the request. Keep the following caveats in mind:

  • If you don't specify the 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 Simple Queue Service 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.

To get the queue URL, use the GetQueueUrl action. GetQueueUrl requires only the QueueName parameter. be aware of existing queue names:

  • If you provide the name of an existing queue along with the exact names and values of all the queue's attributes, CreateQueue returns the queue URL for the existing queue.

  • If the queue name, attribute names, or attribute values don't match an 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:

&Attribute.1=this

&Attribute.2=that

Request Parameters

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

Attribute
Attribute.N.Name (key)
Attribute.N.Value (value)

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). The default is 0 (zero).

  • 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). The default is 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). The default is 345,600 (4 days).

  • Policy - The queue's policy. A valid AWS policy. For more information about policy structure, see Overview of AWS 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). The default is 0 (zero).

  • RedrivePolicy - The string that includes the parameters for the dead-letter queue functionality of the source queue. For more information about the redrive policy and dead-letter queues, see Using Amazon SQS Dead-Letter Queues in the Amazon Simple Queue Service 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.

    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. Valid values: An integer from 0 to 43,200 (12 hours). The default is 30. For more information about the visibility timeout, see Visibility Timeout in the Amazon Simple Queue Service Developer Guide.

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). The default is 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?.

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

  • FifoQueue - Designates a queue as FIFO. Valid values: true, false. 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 Simple Queue Service Developer Guide.

  • ContentBasedDeduplication - Enables content-based deduplication. Valid values: true, false. For more information, see Exactly-Once Processing in the Amazon Simple Queue Service 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.

Any other valid special request parameters (such as the following) are ignored:

  • ApproximateNumberOfMessages

  • ApproximateNumberOfMessagesDelayed

  • ApproximateNumberOfMessagesNotVisible

  • CreatedTimestamp

  • LastModifiedTimestamp

  • QueueArn

Type: String to string map

Valid Keys: All | Policy | VisibilityTimeout | MaximumMessageSize | MessageRetentionPeriod | ApproximateNumberOfMessages | ApproximateNumberOfMessagesNotVisible | CreatedTimestamp | LastModifiedTimestamp | QueueArn | ApproximateNumberOfMessagesDelayed | DelaySeconds | ReceiveMessageWaitTimeSeconds | RedrivePolicy | FifoQueue | ContentBasedDeduplication | KmsMasterKeyId | KmsDataKeyReusePeriodSeconds

Required: No

QueueName

The name of the new queue. The following limits apply to this name:

  • 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 names are case-sensitive.

Type: String

Required: Yes

Response Elements

The following element is returned by the service.

QueueUrl

The URL of the created Amazon SQS queue.

Type: String

Errors

For information about the errors that are common to all actions, see Common Errors.

AWS.SimpleQueueService.QueueDeletedRecently

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

HTTP Status Code: 400

QueueAlreadyExists

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

HTTP Status Code: 400

Example

The following example query request creates a new queue named testQueue. How you structure the AUTHPARAMS depends on how you are signing your API request.
