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 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).
The following list shows the characters (in Unicode) that are allowed in your message, according to the W3C XML specification:
#x9
#xA
#xD
#x20
to #xD7FF
#xE000
to #xFFFD
#x10000
to #x10FFFF
For more information, see RFC1321. If you send any characters that aren't included in this list, your request is rejected.
If you don't specify the 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 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
