GetIntentVersions

Gets information about all of the versions of an intent.

The GetIntentVersions operation returns an IntentMetadata object for each version of an intent. For example, if an intent has three numbered versions, the GetIntentVersions operation returns four IntentMetadata objects in the response, one for each numbered version and one for the $LATEST version.

The GetIntentVersions operation always returns at least one version, the $LATEST version.

This operation requires permissions for the lex:GetIntentVersions action.
