=head1 NAME

Paws::SQS - Perl Interface to AWS Amazon Simple Queue Service

=head1 SYNOPSIS

  use Paws;

  my $obj = Paws->service('SQS');
  my $res = $obj->Method(
    Arg1 => $val1,
    Arg2 => [ 'V1', 'V2' ],
    # if Arg3 is an object, the HashRef will be used as arguments to the constructor
    # of the arguments type
    Arg3 => { Att1 => 'Val1' },
    # if Arg4 is an array of objects, the HashRefs will be passed as arguments to
    # the constructor of the arguments type
    Arg4 => [ { Att1 => 'Val1'  }, { Att1 => 'Val2' } ],
  );

=head1 DESCRIPTION

Welcome to the I<Amazon Simple Queue Service API Reference>.

Amazon Simple Queue Service (Amazon SQS) is a reliable, highly-scalable
hosted queue for storing messages as they travel between applications
or microservices. Amazon SQS moves data between distributed application
components and helps you decouple these components.

Standard queues are available in all regions. FIFO queues are available
in US West (Oregon) and US East (Ohio).

You can use AWS SDKs to access Amazon SQS using your favorite
programming language. The SDKs perform tasks such as the following
automatically:

=head1 METHODS

=head2 AddPermission(Actions => ArrayRef[Str|Undef], AWSAccountIds => ArrayRef[Str|Undef], Label => Str, QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::AddPermission>

Returns: nothing

  Adds a permission to a queue for a specific principal. This allows
sharing access to the queue.

When you create a queue, you have full control access rights for the
queue. Only you, the owner of the queue, can grant or deny permissions
to the queue. For more information about these permissions, see Shared
Queues in the I<Amazon SQS Developer Guide>.

C<AddPermission> writes an Amazon-SQS-generated policy. If you want to
write your own policy, use C< SetQueueAttributes > to upload your
policy. For more information about writing your own policy, see Using
The Access Policy Language in the I<Amazon SQS Developer Guide>.

Some actions take lists of parameters. These lists are specified using
the C<param.n> notation. Values of C<n> are integers starting from 1.
For example, a parameter list with two elements looks like this:

C<&Attribute.1=this>

C<&Attribute.2=that>


=head2 ChangeMessageVisibility(QueueUrl => Str, ReceiptHandle => Str, VisibilityTimeout => Int)

Each argument is described in detail in: L<Paws::SQS::ChangeMessageVisibility>

Returns: nothing

  Changes the visibility timeout of a specified message in a queue to a
new value. The maximum allowed timeout value is 12 hours. Thus, you
can't extend the timeout of a message in an existing queue to more than
a total visibility timeout of 12 hours. For more information, see
Visibility Timeout in the I<Amazon SQS Developer Guide>.

For example, you have a message and with the default visibility timeout
of 5 minutes. After 3 minutes, you call C<ChangeMessageVisiblity> with
a timeout of 10 minutes. At that time, the timeout for the message is
extended by 10 minutes beyond the time of the
C<ChangeMessageVisibility> action. This results in a total visibility
timeout of 13 minutes. You can continue to call the
C<ChangeMessageVisibility> to extend the visibility timeout to a
maximum of 12 hours. If you try to extend the visibility timeout beyond
12 hours, your request is rejected.

A message is considered to be I<in flight> after it's received from a
queue by a consumer, but not yet deleted from the queue.

For standard queues, there can be a maximum of 120,000 inflight
messages per queue. If you reach this limit, Amazon SQS returns the
C<OverLimit> error message. To avoid reaching the limit, you should
delete messages from the queue after they're processed. You can also
increase the number of queues you use to process your messages.

For FIFO queues, there can be a maximum of 20,000 inflight messages per
queue. If you reach this limit, Amazon SQS returns no error messages.

If you attempt to set the C<VisibilityTimeout> to a value greater than
the maximum time left, Amazon SQS returns an error. Amazon SQS doesn't
automatically recalculate and increase the timeout to the maximum
remaining time.

Unlike with a queue, when you change the visibility timeout for a
specific message the timeout value is applied immediately but isn't
saved in memory for that message. If you don't delete a message after
it is received, the visibility timeout for the message reverts to the
original timeout value (not to the value you set using the
C<ChangeMessageVisibility> action) the next time the message is
received.


=head2 ChangeMessageVisibilityBatch(Entries => ArrayRef[L<Paws::SQS::ChangeMessageVisibilityBatchRequestEntry>], QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::ChangeMessageVisibilityBatch>

Returns: a L<Paws::SQS::ChangeMessageVisibilityBatchResult> instance

  Changes the visibility timeout of multiple messages. This is a batch
version of C< ChangeMessageVisibility.> The result of the action on
each message is reported individually in the response. You can send up
to 10 C< ChangeMessageVisibility > requests with each
C<ChangeMessageVisibilityBatch> action.

Because the batch request can result in a combination of successful and
unsuccessful actions, you should check for batch errors even when the
call returns an HTTP status code of C<200>.

Some actions take lists of parameters. These lists are specified using
the C<param.n> notation. Values of C<n> are integers starting from 1.
For example, a parameter list with two elements looks like this:

C<&Attribute.1=this>

C<&Attribute.2=that>


=head2 CreateQueue(QueueName => Str, [Attributes => L<Paws::SQS::QueueAttributeMap>])

Each argument is described in detail in: L<Paws::SQS::CreateQueue>

Returns: a L<Paws::SQS::CreateQueueResult> instance

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

=over

=item *

If you don't specify the C<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 I<Amazon SQS
Developer Guide>.

=item *

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

=item *

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

=back

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 C< GetQueueUrl > action. C< GetQueueUrl >
requires only the C<QueueName> parameter. be aware of existing queue
names:

=over

=item *

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

=item *

If the queue name, attribute names, or attribute values don't match an
existing queue, C<CreateQueue> returns an error.

=back

Some actions take lists of parameters. These lists are specified using
the C<param.n> notation. Values of C<n> are integers starting from 1.
For example, a parameter list with two elements looks like this:

C<&Attribute.1=this>

C<&Attribute.2=that>


=head2 DeleteMessage(QueueUrl => Str, ReceiptHandle => Str)

Each argument is described in detail in: L<Paws::SQS::DeleteMessage>

Returns: nothing

  Deletes the specified message from the specified queue. You specify the
message by using the message's I<receipt handle> and not the
I<MessageId> you receive when you send the message. Even if the message
is locked by another reader due to the visibility timeout setting, it
is still deleted from the queue. If you leave a message in the queue
for longer than the queue's configured retention period, Amazon SQS
automatically deletes the message.

The receipt handle is associated with a specific instance of receiving
the message. If you receive a message more than once, the receipt
handle you get each time you receive the message is different. If you
don't provide the most recently received receipt handle for the message
when you use the C<DeleteMessage> action, the request succeeds, but the
message might not be deleted.

For standard queues, it is possible to receive a message even after you
delete it. This might happen on rare occasions if one of the servers
storing a copy of the message is unavailable when you send the request
to delete the message. The copy remains on the server and might be
returned to you on a subsequent receive request. You should ensure that
your application is idempotent, so that receiving a message more than
once does not cause issues.


=head2 DeleteMessageBatch(Entries => ArrayRef[L<Paws::SQS::DeleteMessageBatchRequestEntry>], QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::DeleteMessageBatch>

Returns: a L<Paws::SQS::DeleteMessageBatchResult> instance

  Deletes up to ten messages from the specified queue. This is a batch
version of C< DeleteMessage.> The result of the action on each message
is reported individually in the response.

Because the batch request can result in a combination of successful and
unsuccessful actions, you should check for batch errors even when the
call returns an HTTP status code of C<200>.

Some actions take lists of parameters. These lists are specified using
the C<param.n> notation. Values of C<n> are integers starting from 1.
For example, a parameter list with two elements looks like this:

C<&Attribute.1=this>

C<&Attribute.2=that>


=head2 DeleteQueue(QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::DeleteQueue>

Returns: nothing

  Deletes the queue specified by the C<QueueUrl>, even if the queue is
empty. If the specified queue doesn't exist, Amazon SQS returns a
successful response.

Be careful with the C<DeleteQueue> action: When you delete a queue, any
messages in the queue are no longer available.

When you delete a queue, the deletion process takes up to 60 seconds.
Requests you send involving that queue during the 60 seconds might
succeed. For example, a C< SendMessage > request might succeed, but
after 60 seconds the queue and the message you sent no longer exist.

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


=head2 GetQueueAttributes(QueueUrl => Str, [AttributeNames => ArrayRef[Str|Undef]])

Each argument is described in detail in: L<Paws::SQS::GetQueueAttributes>

Returns: a L<Paws::SQS::GetQueueAttributesResult> instance

  Gets attributes for the specified queue.

To determine whether a queue is FIFO, you can check whether
C<QueueName> ends with the C<.fifo> suffix.

Some actions take lists of parameters. These lists are specified using
the C<param.n> notation. Values of C<n> are integers starting from 1.
For example, a parameter list with two elements looks like this:

C<&Attribute.1=this>

C<&Attribute.2=that>


=head2 GetQueueUrl(QueueName => Str, [QueueOwnerAWSAccountId => Str])

Each argument is described in detail in: L<Paws::SQS::GetQueueUrl>

Returns: a L<Paws::SQS::GetQueueUrlResult> instance

  Returns the URL of an existing queue. This action provides a simple way
to retrieve the URL of an Amazon SQS queue.

To access a queue that belongs to another AWS account, use the
C<QueueOwnerAWSAccountId> parameter to specify the account ID of the
queue's owner. The queue's owner must grant you permission to access
the queue. For more information about shared queue access, see C<
AddPermission > or see Shared Queues in the I<Amazon SQS Developer
Guide>.


=head2 ListDeadLetterSourceQueues(QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::ListDeadLetterSourceQueues>

Returns: a L<Paws::SQS::ListDeadLetterSourceQueuesResult> instance

  Returns a list of your queues that have the C<RedrivePolicy> queue
attribute configured with a dead letter queue.

For more information about using dead letter queues, see Using Amazon
SQS Dead Letter Queues in the I<Amazon SQS Developer Guide>.


=head2 ListQueues([QueueNamePrefix => Str])

Each argument is described in detail in: L<Paws::SQS::ListQueues>

Returns: a L<Paws::SQS::ListQueuesResult> instance

  Returns a list of your queues. The maximum number of queues that can be
returned is 1,000. If you specify a value for the optional
C<QueueNamePrefix> parameter, only queues with a name that begins with
the specified value are returned.


=head2 PurgeQueue(QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::PurgeQueue>

Returns: nothing

  Deletes the messages in a queue specified by the C<QueueURL> parameter.

When you use the C<PurgeQueue> action, you can't retrieve a message
deleted from a queue.

When you purge a queue, the message deletion process takes up to 60
seconds. All messages sent to the queue before calling the
C<PurgeQueue> action are deleted. Messages sent to the queue while it
is being purged might be deleted. While the queue is being purged,
messages sent to the queue before C<PurgeQueue> is called might be
received, but are deleted within the next minute.


=head2 ReceiveMessage(QueueUrl => Str, [AttributeNames => ArrayRef[Str|Undef], MaxNumberOfMessages => Int, MessageAttributeNames => ArrayRef[Str|Undef], ReceiveRequestAttemptId => Str, VisibilityTimeout => Int, WaitTimeSeconds => Int])

Each argument is described in detail in: L<Paws::SQS::ReceiveMessage>

Returns: a L<Paws::SQS::ReceiveMessageResult> instance

  Retrieves one or more messages (up to 10), from the specified queue.
Using the C<WaitTimeSeconds> parameter enables long-poll support. For
more information, see Amazon SQS Long Polling in the I<Amazon SQS
Developer Guide>.

Short poll is the default behavior where a weighted random set of
machines is sampled on a C<ReceiveMessage> call. Thus, only the
messages on the sampled machines are returned. If the number of
messages in the queue is small (fewer than 1,000), you most likely get
fewer messages than you requested per C<ReceiveMessage> call. If the
number of messages in the queue is extremely small, you might not
receive any messages in a particular C<ReceiveMessage> response. If
this happens, repeat the request.

For each message returned, the response includes the following:

=over

=item *

The message body.

=item *

An MD5 digest of the message body. For information about MD5, see
RFC1321.

=item *

The C<MessageId> you received when you sent the message to the queue.

=item *

The receipt handle.

=item *

The message attributes.

=item *

An MD5 digest of the message attributes.

=back

The receipt handle is the identifier you must provide when deleting the
message. For more information, see Queue and Message Identifiers in the
I<Amazon SQS Developer Guide>.

You can provide the C<VisibilityTimeout> parameter in your request. The
parameter is applied to the messages that Amazon SQS returns in the
response. If you don't include the parameter, the overall visibility
timeout for the queue is used for the returned messages. For more
information, see Visibility Timeout in the I<Amazon SQS Developer
Guide>.

A message that isn't deleted or a message whose visibility isn't
extended before the visibility timeout expires counts as a failed
receive. Depending on the configuration of the queue, the message might
be sent to the dead letter queue.

In the future, new attributes might be added. If you write code that
calls this action, we recommend that you structure your code so that it
can handle new attributes gracefully.


=head2 RemovePermission(Label => Str, QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::RemovePermission>

Returns: nothing

  Revokes any permissions in the queue policy that matches the specified
C<Label> parameter. Only the owner of the queue can remove permissions.


=head2 SendMessage(MessageBody => Str, QueueUrl => Str, [DelaySeconds => Int, MessageAttributes => L<Paws::SQS::MessageBodyAttributeMap>, MessageDeduplicationId => Str, MessageGroupId => Str])

Each argument is described in detail in: L<Paws::SQS::SendMessage>

Returns: a L<Paws::SQS::SendMessageResult> instance

  Delivers a message to the specified queue.

A message can include only XML, JSON, and unformatted text. The
following Unicode characters are allowed:

C<#x9> | C<#xA> | C<#xD> | C<#x20> to C<#xD7FF> | C<#xE000> to
C<#xFFFD> | C<#x10000> to C<#x10FFFF>

Any characters not included in this list will be rejected. For more
information, see the W3C specification for characters.


=head2 SendMessageBatch(Entries => ArrayRef[L<Paws::SQS::SendMessageBatchRequestEntry>], QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::SendMessageBatch>

Returns: a L<Paws::SQS::SendMessageBatchResult> instance

  Delivers up to ten messages to the specified queue. This is a batch
version of C< SendMessage.> For a FIFO queue, multiple messages within
a single batch are enqueued in the order they are sent.

The result of sending each message is reported individually in the
response. Because the batch request can result in a combination of
successful and unsuccessful actions, you should check for batch errors
even when the call returns an HTTP status code of C<200>.

The maximum allowed individual message size and the maximum total
payload size (the sum of the individual lengths of all of the batched
messages) are both 256 KB (262,144 bytes).

A message can include only XML, JSON, and unformatted text. The
following Unicode characters are allowed:

C<#x9> | C<#xA> | C<#xD> | C<#x20> to C<#xD7FF> | C<#xE000> to
C<#xFFFD> | C<#x10000> to C<#x10FFFF>

Any characters not included in this list will be rejected. For more
information, see the W3C specification for characters.

If you don't specify the C<DelaySeconds> parameter for an entry, Amazon
SQS uses the default value for the queue.

Some actions take lists of parameters. These lists are specified using
the C<param.n> notation. Values of C<n> are integers starting from 1.
For example, a parameter list with two elements looks like this:

C<&Attribute.1=this>

C<&Attribute.2=that>


=head2 SetQueueAttributes(Attributes => L<Paws::SQS::QueueAttributeMap>, QueueUrl => Str)

Each argument is described in detail in: L<Paws::SQS::SetQueueAttributes>

Returns: nothing

  Sets the value of one or more queue attributes. 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 C<MessageRetentionPeriod> attribute can take up to 15
minutes.

In the future, new attributes might be added. If you write code that
calls this action, we recommend that you structure your code so that it
can handle new attributes gracefully.
