Hi there Doctordrip1346, my name is Gerardo, and I'm an Xbox player, just like you. I'll be happy to assist you with any questions or concerns you may have.

If you redeem an Xbox gift card on your Microsoft account, you will receive a balance that you can use to pay for the V-Bucks you want to purchase.

Once you have redeemed the gift card, you should go to the Microsoft Store to buy the V-Bucks. When you are about to make the payment, you will be asked how you want to pay, and you should choose the balance from your Microsoft account.

For example, if you want to buy 1000 V-Bucks, you should go to the following website:

https://www.xbox.com/games/store/fortnite-1000-v-bucks/c0f5ht9nv86p

Choose your Microsoft account balance as the payment method.

If you want to buy a different amount of V-Bucks and don't know how to find the purchase link, please let me know how many V-Bucks you want, and I can gladly search for the purchase link for you and share it with you.

I hope this helps and if you have further questions please let me know.

Kind regards,
Gerardo.

Hi, I redeemed a gift card through my microsoft account, and expected it to be available on the x-box (one of the devices attached to my account) but it's not available on the x-box. how can I make this available from the x-box?

From the X box website where you can purchase digital gift cards. Not from a 3rd party. From the x box website
