providing free in-app purchases to select people

Question

I have an app that is being funded through a donation website that includes rewards. Some of the rewards I want to do is a free set of in-app purchases. Is this possible on google play? Can I manually do discount codes, or is there a systematic way to do it? Any other ideas?

Thanks!

Answer 1

The only thing I have found is to e-mail the APK for the game itself and manage the details in a database, and change the numbers. I'll mark this is the accepted answer, but if someone comes up with something else, I'll happily change it.

You can implement give-away coupons with redeemable codes for your in-app products using the new in-app promotions Play Store feature:

You can create up to 500 promo codes for a month and send them to your supporters.
