purchase

purchase method of REST API is used to send the data about a user's game verified purchases. If the user has never logged the game in before, the new profile will be created for the user in Game of Whales.

Pay attention that by default Game of Whales doesn't make verification of purchases received through purchase method. All purchases (including refunds, restores, cheater's purchases) will increase the stats. So in order to have correct stats, a game developer should verify purchases on the game side and send the data only about legal purchases to Game of Whales system.
If it's needed to verify purchases on Game of Whales side, the special parameter verify should be set in purchase method or receipt method should be used. Game of Whales supports verification of purchases from Google Play, Apple App Store and Samsung Store only.
