How to download game from gift card

Hi,Christine ! I'm Luis, a fellow Xbox Gamer . Thanks for reaching us out here.

Go to microsoft.com/redeem, log into your Microsoft account, and enter the 25-character code provided

After that the game will be automatically added to your library

Back on your console:

Go to My games & apps > See all > Full library > All owned games, select the game title, then press Install all.

this is to a moderator/xbox staff member: (regarding xbox avatar store/marketplace)

instead of using a credit card as a payment option could i use an xbox gift card? say the gift card was $10.00. any time i bought an avatar prop the amount would be deducted from the $10.00, correct? once that amount is gone i'd get another gift card to
replace it? how do i know how much is left on the gift card?

Greetings Boydboyz,

Unfortunately, once a gift card is redeemed, it cannot be transferred over. However, you can gift purchases from that account over to yours using the gift card as the payment method.

To learn more about how to gift purchases, check out the following article here.

I have now found a way to buy games from microsoft by changing location and buying gift cards with my Thailand credit card. It works... GTA V is downloading as I write!

Hi! Backwards Compatible games can not be purchased using gift cards\account credit but, if you can get access to an Xbox 360, you can use the gift card to purchase it from the Xbox 360 then download it via Ready to Install on your Xbox One.

Hope that helps!
