# Google Play Promo Code Reward

> Trial subscription offer on Google Play.

With WinWinKit you can reward users with a promo code giving them a free month or extended trial when starting a subscription via Google Play.

<Warning>
    Because Google Play does not provide API interface for creating and fetching promo codes, the promo codes need to be manually created and uploaded to WinWinKit with a .csv file.
</Warning>

## Examples

- Free Month: Reward with a free month of their active subscription for each invited user.
- Trial Period: Enable a trial period on a subscription that otherwise is not available.
