You can now generate and distribute promo codes for your app or game to current and new users on Google Play.
Under the Promotions tab in the Google Play Developer Console, you can set up promo codes for your apps, games, and in-app products to distribute in your own marketing campaigns (up to 500 codes per app, per quarter):
- Go to your Google Play Developer Console, select your app.
- Select Promotions > Add new promotion.
- Follow the on-screen instructions (promotion name, start and end dates, promotion type, number of promo codes you want to create).
- Select Create, select the download link. Your codes will download to a CSV file. To share with users, you can print the codes or send a deep link allowing users to redeem the codes via email or a notification within your app.
