While you are waiting for Facebook to approve your Facebook App, we also support polling for messages which will allow users to interact with your bot in the meantime.
To enable this, return to your bot's Admin Console on the Bot Libre website and go to the "Facebook" tab.
Click "Reply to messages (poll for messages)" and then "Save" to enable this feature. This does not require Facebook to approve your App.
You should disable this feature once your Facebook App has been approved, otherwise your bot will reply to messages twice.
