FIFO queues supported (.fifo suffix); accepts tags inline | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_CreateQueue.html) | | `DeleteQueue` | ✅ Supported | | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_DeleteQueue.html) | | `GetQueueUrl` | ✅ Supported | | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_GetQueueUrl.html) | | `ListQueues` | ✅ Supported | Optional QueueNamePrefix filter | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_ListQueues.html) | | `GetQueueAttributes` | ✅ Supported | All standard attributes including CreatedTimestamp, LastModifiedTimestamp and ApproximateNumberOfMessagesDelayed; an unmodelled attribute name is rejected with InvalidAttributeName; All wildcard supported from any position in the list; ApproximateNumberOfMessages(NotVisible/Delayed) reflects the same counts a background sampler also publishes to CloudWatch every minute as ApproximateNumberOfMessagesVisible/NotVisible/Delayed, whether or not the queue has traffic | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_GetQueueAttributes.html) | | `SetQueueAttributes` | ✅ Supported | RedriveAllowPolicy accepted, validated, and round-tripped; the redrivePermission restriction itself is not enforced against StartMessageMoveTask or automatic DLQ redrive | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_SetQueueAttributes.html) | | `PurgeQueue` | ✅ Supported | Deletes all messages immediately | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_PurgeQueue.html) | | `ListQueueTags` | ✅ Supported | | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_ListQueueTags.html) | | `TagQueue` | ✅ Supported | Merges with existing tags | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_TagQueue.html) | | `UntagQueue` | ✅ Supported | | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_UntagQueue.html) | ### Message operations | Operation | Status | Notes | AWS Docs | | --- | --- | --- | --- | | `SendMessage` | ✅ Supported | DelaySeconds, MessageAttributes supported, with MD5OfMessageAttributes returned when attributes are present; records AWS/SQS CloudWatch metrics NumberOfMessagesSent and SentMessageSize, skipped for a FIFO content-based-deduplication resend since no new message is enqueued | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_SendMessage.html) | | `SendMessageBatch` | ✅ Supported | Up to 10 messages per batch, enforced — an empty batch, an oversized one or duplicate entry Ids are rejected whole; MD5OfMessageAttributes returned per entry; records NumberOfMessagesSent/SentMessageSize per successful entry | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_SendMessageBatch.html) | | `ReceiveMessage` | ✅ Supported | MaxNumberOfMessages, VisibilityTimeout, WaitTimeSeconds, queue default long polling, FIFO ReceiveRequestAttemptId with its 5-minute replay window; a FIFO batch drains one message group in sequence order before filling from other unblocked groups; the in-flight OverLimit quota is not enforced; records NumberOfMessagesReceived (non-empty) or NumberOfEmptyReceives (zero messages) once per call, after any long-poll retry settles | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_ReceiveMessage.html) | | `DeleteMessage` | ✅ Supported | Records NumberOfMessagesDeleted | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_DeleteMessage.html) | | `DeleteMessageBatch` | ✅ Supported | Up to 10 messages per batch, enforced — an empty batch, an oversized one or duplicate entry Ids are rejected whole; records NumberOfMessagesDeleted per successful entry | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_DeleteMessageBatch.html) | | `ChangeMessageVisibility` | ✅ Supported | Sets new visibility timeout on an in-flight message | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_ChangeMessageVisibility.html) | | `ChangeMessageVisibilityBatch` | ✅ Supported | Batch visibility timeout changes; up to 10 entries, enforced — an empty batch, an oversized one or duplicate entry Ids are rejected whole; per-entry success/failure response | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_ChangeMessageVisibilityBatch.html) | ### Permissions | Operation | Status | Notes | AWS Docs | | --- | --- | --- | --- | | `AddPermission` | ❌ Unsupported | stub; returns 501 | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_AddPermission.html) | | `RemovePermission` | ❌ Unsupported | stub; returns 501 | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_RemovePermission.html) | ### Dead-letter queues | Operation | Status | Notes | AWS Docs | | --- | --- | --- | --- | | `ListDeadLetterSourceQueues` | ✅ Supported | Lists queues that target a given DLQ | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_ListDeadLetterSourceQueues.html) | | `StartMessageMoveTask` | ✅ Supported | Redrives messages from a DLQ back to its source queue | [docs](https://docs.aws.amazon.com/AWSSimpleQueueService/latest/APIReference/API_StartMessageMoveTask.html) | ## Related - [SQS](/docs/services/sqs/index.md) — quick start, what works, and the differences from AWS - [All service pages](/docs/services/index.md)
