The following Unicode characters are allowed:. Any characters not included in this list will be rejected. For more information, see the W3C specification for characters. For information about the parameters that are common to all actions, see Common Parameters. The length of time, in seconds, for which to delay a specific message.
Messages with a positive DelaySeconds value become available for processing after the delay period is finished. If you don't specify a value, the default value for the queue applies. When you set FifoQueueyou can't set DelaySeconds per message. You can set this parameter only on a queue level.
Each message attribute consists of a NameTypeand Value. The token used for deduplication of sent messages. If a message with a particular MessageDeduplicationId is sent successfully, any messages sent with the same MessageDeduplicationId are accepted successfully but aren't delivered during the 5-minute deduplication interval.
If you don't provide a MessageDeduplicationId and the queue doesn't have ContentBasedDeduplication set, the action fails with an error. 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 blockchain api sendmessage one message with ContentBasedDeduplication enabled and then another message with a MessageDeduplicationId that is the same as the one generated for the first MessageDeduplicationIdthe two messages are treated as duplicates and only one copy of the message is delivered.
The MessageDeduplicationId is available to blockchain api sendmessage consumer of the message this can be useful for troubleshooting delivery issues. If a message is sent successfully but the acknowledgement is lost and the message is resent with the same MessageDeduplicationId after the deduplication interval, Amazon SQS can't detect duplicate messages.
Amazon SQS continues to blockchain api sendmessage track of blockchain api sendmessage message deduplication ID even after the message is received and deleted. The length of MessageDeduplicationId is characters. MessageDeduplicationId can contain alphanumeric characters a-zA-Z blockchain api sendmessage, and punctuation!
The tag that specifies that a message belongs to a specific message group. Messages that belong to the same message blockchain api sendmessage are processed in a FIFO manner however, messages in different message groups might be processed out of order.
To interleave multiple ordered streams within a single queue, use MessageGroupId values for example, session data for multiple users. In this scenario, multiple consumers can process the queue, but the session data of each user is processed in a FIFO fashion. You must associate a non-empty MessageGroupId with a message. If you don't provide a MessageGroupIdthe action fails. ReceiveMessage might return messages with multiple MessageGroupId values.
For each MessageGroupIdthe messages are sorted by time sent. The caller can't specify a MessageGroupId. The length of MessageGroupId is characters. You can't use it for Standard queues. You can use this attribute to verify that Amazon SQS received the message correctly. An attribute blockchain api sendmessage the MessageId of the message sent to the queue.
The length of Blockchain api sendmessage is bits. SequenceNumber continues to increase for a particular MessageGroupId. For information about the errors that are common to all actions, see Common Errors. The following example SendMessage request sends a message containing This is a test message to the queue. However, in this example only the message body is URL-encoded to make the example easier to read. The following example creates a message timer —applying a second initial visibility delay to a single message— by calling blockchain api sendmessage SendMessage action with the DelaySeconds parameter set to 45 seconds.
Note The MessageDeduplicationId is available to the consumer of the message this can be useful for troubleshooting delivery issues. The large, non-consecutive number that Amazon SQS assigns to each message.
