2021/10/19 - Amazon Chime SDK Messaging - 13 new 5 updated api methods
Changes The Amazon Chime SDK now allows developers to execute business logic on in-flight messages before they are delivered to members of a messaging channel with channel flows.
Lists all channels associated with a specified channel flow. You can associate a channel flow with multiple channels, but you can only associate a channel with one channel flow. This is a developer API.

Deletes a channel flow, an irreversible process. This is a developer API.
Note
This API works only when the channel flow is not associated with any channel. To get a list of all channels that a channel flow is associated with, use the ListChannelsAssociatedWithChannelFlow API. Use the DisassociateChannelFlow API to disassociate a channel flow from all channels.

None
Gets message status for a specified messageId . Use this API to determine the intermediate status of messages going through channel flow processing. The API provides an alternative to retrieving message status if the event was not received because a client wasn't connected to a websocket.
Messages can have any one of these statuses.
SENT
Message processed successfully
PENDING
Ongoing processing
FAILED
Processing failed
DENIED
Messasge denied by the processor
Note
This API does not return statuses for denied messages, because we don't store them once the processor denies them.
Only the message sender can invoke this API.
The x-amz-chime-bearer request header is mandatory. Use the AppInstanceUserArn of the user that makes the API call as the value in the header

Creates a channel flow, a container for processors. Processors are AWS Lambda functions that perform actions on chat messages, such as stripping out profanity. You can associate channel flows with channels, and the processors in the channel flow then take action on all messages sent to that channel. This is a developer API.
Channel flows process the following items:
New and updated messages
Persistent and non-persistent messages
The Standard message type
Note
Channel flows don't process Control or System messages. For more information about the message types provided by Chime SDK Messaging, refer to Message types in the Amazon Chime developer guide .
