Description

IPurchaseCallback.OnConsumeSucceeded() in the In-app payment service supported by ONE store accepts the receipt for the purchased product and verifies it via the BACKND server.

  • BACKND verifies the validity of the receipt itself and the purchased productId.
  • You must be logged in to BACKND to use its verification function.

Example

Synchronous

    public void BuyButton(int i)
{
string productId = "gold";

// Payment logic
ProductType productType = ProductType.INAPP;
var purchaseFlowParams = new PurchaseFlowParams.Builder()
.SetProductId(productId) // Needs to be added
.SetProductType(productType) // Needs to be added
.SetDeveloperPayload("Enter any additional information if necessary") // Optional
.Build();
purchaseClient.Purchase(purchaseFlowParams);
}

public void OnPurchaseSucceeded(List<PurchaseData> purchases)
{
/*
Processing BACKND receipt verification
*/
for(int i = 0; i < purchases.Count; i++) {

BackendReturnObject validation = Backend.Receipt.IsValidateOneStorePurchase(purchases[i].ProductId, purchases[i].PurchaseToken, "receiptDescription");

// When receipt verification is successful
if (validation.IsSuccess()) {
Debug.Log($"ProcessPurchase: PASS. Product: {purchases[i].ProductId}");

if (purchases[i].ProductId == "gold") {
// Hand out Gold
}

} else {
Debug.Log($"ProcessPurchase: FAIL. Unrecognized product: {purchases[i].ProductId}");
}
}
}

Asynchronous
