Player card approval is url based or app based?


we are investigating the possibility to implement twitter player card on our product for video we provide to our client.
The videos all hosted to the same domain, but they will be posted on twitter using different twitter apps.
So, I’m wondering if I need to ask approval for each app of my clients, or I can ask approval just once for my domain where the video and player is hosted ?



The player cards are validated based on hosting domain.
