CreateBotVersion

Creates a new version of the bot based on the $LATEST version. If the $LATEST version of this resource hasn't changed since you created the last version, Amazon Lex doesn't create a new version. It returns the last created version.

Note

You can update only the $LATEST version of the bot. You can't update the numbered versions that you create with the CreateBotVersion operation.

When you create the first version of a bot, Amazon Lex sets the version to 1. Subsequent versions increment by 1. For more information, see Versioning.

This operation requires permission for the lex:CreateBotVersion action.
