how to add button in notification

[duongsieu]

i add params buttuon in prepareParams but response from onesignal:

Client error: POST https://onesignal.com/api/v1/notifications resulted in a 400 Bad Request response:\n{"errors":["Invalid 'buttons' format!"]}\n

I have tried many different formats like string, array, json endcode array,... but it doesn't work. Can you help me format this so I can send it successfully, thanks

return OneSignal::sendNotificationToAll(
$message,
$url,
['abc' => 123, 'foo' => 'bar', 'event_performed' => true, 'amount' => 12.1],
[["id" => "id1", "text" => "first button", "icon" => "ic_menu_share"], ["id" => "id2", "text" => "second button", "icon" => "ic_menu_send"]],
$schedule = null,
$heading,
);

figured it out myself. FYI plugin is good but documentation is poor.
