Game Pass Subscription and Gift Cards

There is xbox live game pass gift cards same with xbox live gold gift cards. Currency gift cards can't really play for subscription payments.

Was it gift cards because thats the rewards I'm still waiting for

Different winner here. There were three prizes for me: game pass subscription, gift card, and Xbox gift card.

I've received the first two things. Still waiting on the Xbox gift card.

You cannot use your balance to pay for subscriptions

You are required to have a credit card on file to subscribe to services and a test charge will be made, and the $1 charged to your card.

If you wish to purchase Game Pass with a gift card you have to get Game Pass specific gift cards

If the gift card says Game Pass on it, then it will only be for Game Pass. It should state if it's for the console or PC. If it's a regular Xbox gift card that adds funds to your account, you can purchase Game Pass with it as long as you have enough to
cover the next payment since it starts a recurring subscription or you have a credit card or Paypal on file.

Actually you can use funds from a gift card to purchase subscriptions, you just need enough to cover the next payment or a cr we dit card/Paypal on file as well.

It would probably be better to use the Microsoft Rewards points on a game pass subscription instead of a gift card if you can though to make it easier to gift it to them.
