Are there only credit rewards for certain achievements and purchases on the xbox store?

In order to receive credits, your purchases either have to be eligible for a specific offer on the site at the time, or you need at least 1 star level in order to receive VIP rebates. a

Achievements only earn credits if they are part of a specific offer which usually involves purchasing a game for a specific genre and then earning a certain number of achievements in that game.

All offers for earning credits are listed on the Missions page of the rewards site.

Hello DDXDB,

Since you are registered as a US Rewards member, only purchases made off the Xbox store in USD are eligible for Rewards. If you opt-out of the Rewards program, you delete this Rewards account, so all the Credits and Gems associated with the account will
be deleted. However, we will be able to recover any pending, un-deposited Credits to any new Rewards Account. Since achievements are saved to your Xbox profile and not a Rewards Account, they will not be deleted. Therefore, it would not be possible to repeat
these achievements for calculating gems.

For help with the Rewards program, it's best to post in the Xbox Rewards Questions forum, but no. Only purchases from the Xbox Store (and sometimes microsoftstore.com) are eligible for Rewards credits.

Microsoft Rewards or Xbox Rewards? The Microsoft Rewards program is separate from the Xbox Rewards program so Xbox Rewards support would not be able to assist if that's what you're referring to.

If you are referring to the Xbox Rewards program, there are generally no offers to receive credits just for achievements. In order to earn credits for achievements, they have to be part of a specific offer on the site at the time. Generally the offers involve
purchasing a specific game that is eligible for the offer and then earning a set number of achievements in that game.

You may also be confusing the previous MyAchievements program with earning credits for achievements. MyAchievements was the previous version of the VIP program which ended September 2014 when the program switched to the current star levels. With MyAchievements
your VIP rebates were based on gamerscore and the rebates were for purchases made in the store, not for earning achievements.

You'll want to post in the Xbox Rewards Questions forum in order for support to check your account. Keep in mind that in order to receive credits, your purchases either have to be eligible for a specific offer on the site at the time, or you need at least
1 star level in order to receive VIP rebates.

Achievements only earn credits if they are part of a specific offer (like the current Dr. Rewards offer). In order to receive credits, you have to first purchase a specific game that is eligible for the offer and then earn a certain number of credits in
that game.
