To let the connector work properly you should define an application name in `config/pumpio.config.php`: return [ 'pumpio' => [ 'application_name' => '', // Displays forwarded posts like "wall-to-wall" posts. 'wall-to-wall_share' => false, // Given in minutes 'poll_interval' => 5, ], ]; This name appears at pump.io and is important for not mirroring back posts that came from Friendica.
