createQueue

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

• If you don't specify the FifoQueue attribute, Amazon SQS creates a standard queue.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.

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.
