Sending messages in Amazon Chime SDK messaging

You use the SendChannelMessage API to send messages to a channel. For a channel associated with a channel flow, the processor assigns one of the following status values.

Message status Description

SENT

Message processed successfully.

PENDING

Ongoing processing.

FAILED

Processing failed because the processor Lambda function is unreachable.

DENIED

The message won't be sent.
Receiving intermediate status events

Websocket events are sent to a channel after they successfully establish a connection. For more information, refer to Using WebSockets to receive messages in Amazon Chime SDK messaging.

GetChannelMessageStatus API

This API provides an alternative way to retrieve message status if the event was not received due to a bad websocket connection. For more information, refer to the GetChannelMessageStatus API documentation.

Note

This API does not return statuses for denied messages, because we don't store them.
