ListChannelMessages

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.

Important

This API is no longer supported and will not be updated. We recommend using the latest version, ListChannelMessages, in the Amazon Chime SDK.

Using the latest version requires migrating to a dedicated namespace. For more information, refer to Migrating from the Amazon Chime namespace in the Amazon Chime SDK Developer Guide.
