list_channel_messages

ChimeSDKMessaging.Client.list_channel_messages(**kwargs)

List all the messages in a channel. Returns a paginated list of ChannelMessages . By default, sorted by creation timestamp in descending order.

Note

Redacted messages appear in the results as empty, since they are only redacted, not deleted. Deleted messages do not appear in the results. This action always returns the latest version of an edited message.

Also, 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.
