/intents/{name}/versions

http://models.lex.{region}.amazonaws.com/intents/{name}/versions

Creates a new version of an intent based on the <code>$LATEST</code> version of the intent. If the <code>$LATEST</code> version of this intent hasn't changed since you last updated it, Amazon Lex doesn't create a new version. It returns the last version you created. <note> You can update only the <code>$LATEST</code> version of the intent. You can't update the numbered versions that you create with the <code>CreateIntentVersion</code> operation. </note> When you create a version of an intent, Amazon Lex sets the version to 1. Subsequent versions increment by 1. For more information, see <a>versioning-intro</a>. This operation requires permissions to perform the <code>lex:CreateIntentVersion</code> action.

Path Parameters

The name of the intent that you want to create a new version of. The name is case sensitive.

Body Params

checksumstring

Checksum of the <code>$LATEST</code> version of the intent that should be used to create the new version. If you specify a checksum and the <code>$LATEST</code> version of the intent has a different checksum, Amazon Lex returns a <code>PreconditionFailedException</code> exception and doesn't publish a new version. If you don't specify a checksum, Amazon Lex publishes the <code>$LATEST</code> version.
