Netflix normally payable with a card from India?

As is the case with Netflix, how and where can I redeem the card codes (I would set up an Acc tomorrow) and I can't pay with a credit card, etc. Cards, so the "gift cards" Acc on the PS4

The only option is to buy a Netflix gift card. With this code you can then use Netflix.

So buy normally and redeem on the site?

Yes exactly. For example at Amazon. https://www.amazon.de/...07HD1LS78/ e.g.

Thank you
