**Important**  
End of support notice: On May 20,2026, Amazon will end support for Amazon IoT Events. After May 20,2026, you will no longer be able to access the Amazon IoT Events console or Amazon IoT Events resources. For more information, see [Amazon IoT Events end of support](https://docs.amazonaws.cn/iotevents/latest/developerguide/iotevents-end-of-support.html). 

Sends a set of messages to the Amazon IoT Events system. Each message payload is transformed into the input you specify (`"inputName"`) and ingested into any detectors that monitor that input. If multiple messages are sent, the order in which the messages are processed isn't guaranteed. To guarantee ordering, you must send messages one at a time and wait for a successful response.

The following limits apply: 
+ Maximum messages per batch: 10
+ Maximum message payload per batch: 1024 Bytes (1 KiB)
