Implement import

• Create a new importer class extending ABoardImportService

• Create a listener for event BoardImportGetAllowedEvent to enable your importer.

  You can read more about listeners on Nextcloud doc.

  Example:

class YourCustomImporterListener {
    public function handle(Event $event): void {
        if (!($event instanceof BoardImportGetAllowedEvent)) {
            return;
        }

        $event->getService()->addAllowedImportSystem([
            'name' => YourCustomImporterService::$name,
            'class' => YourCustomImporterService::class,
            'internalName' => 'YourCustomImporter'
        ]);
    }
}

• Register your listener on your Application class like this:

$dispatcher = $this->getContainer()->query(IEventDispatcher::class);
$dispatcher->registerEventListener(
    BoardImportGetAllowedEvent::class,
    YourCustomImporterListener::class
);

• Use the lib/Service/Importer/Systems/TrelloJsonService.php class as inspiration
