use GrapheneNodeClient\Connectors\ConnectorInterface;

class MyConnector implements ConnectorInterface 
{
    /**
    * platform name for witch connector is. steemit or golos.
    */
    public function getPlatform() {
     // TODO: Implement getPlatform() method.
    }
    
    /**
    * @param string $apiName calling api name - follow_api, database_api and ect.
    * @param array  $data    options and data for request
    * @param string $answerFormat
