Get Supported Features

To ensure that your bot will work properly on the version of Messenger that the user has, you can call getSupportedFeatures() to get a list of features that are supported on the current client returned as an array of strings.

If a feature you depend on is not available, you can use this opportunity to fail gracefully with a message telling the user to upgrade.

<script>
      MessengerExtensions.getSupportedFeatures(function success(result) {
        var features = result.supported_features;
      }, function error(err) {

      });
</script>
