question

Hello, everyone

I’m integrating non-recept payments into my game (with paypal) and i'm having an issue with the confirm payments. Specifically with the PayerID missing. I double checked my merchant ID within PayPal and in PlayFab and it seems to be correct.

The whole error message is this:

/Client/ConfirmPurchase: Failed by payment provider
ProviderErrorCode: 1
ProviderErrorMessage: Failure
ProviderErrorDetails: FinalizeTransaction failed, Ack=FailureExpress Checkout PayerID is missing.
The PayerID value is invalid.

ProviderOrderId:
UnityEngine.Debug:LogError(Object)
<>c:<confirmPurchase>b__2_1(PlayFabError) (at Assets/Scripts/PayPalController.cs:61)
PlayFab.Internal.PlayFabUnityHttp:OnResponse(String, CallRequestContainer) (at Assets/PlayFabSDK/Shared/Internal/PlayFabHttp/PlayFabUnityHttp.cs:260)
PlayFab.Internal.<Post>d__12:MoveNext() (at Assets/PlayFabSDK/Shared/Internal/PlayFabHttp/PlayFabUnityHttp.cs:190)
UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr) (at C:/buildslave/unity/build/Runtime/Export/Coroutines.cs:17)

I have a hunch it is due to the way my code is set up. I’m unsure where to put the ‘confirmPurchase(orderid)’ line. I know a paypal window is supposed to appear but i never see that it does. I believe my issue will be within either payForPurchase() or confirmPurchase().

PlayFabClientAPI.StartPurchase(new StartPurchaseRequest()
        {
            CatalogVersion = "IAP1_0",
            Items = new List<ItemPurchaseRequest>() 
            {
                new ItemPurchaseRequest() 
                {
                    ItemId = "One",
                    Quantity = 1,
                    Annotation = "Purchased via in-game store"
                }
            }
        }, result => {
            // Handle success
            Debug.Log(result);
            payForPurchase(result.OrderId);
        }, error => {
            // Handle error
            Debug.LogError(error.GenerateErrorReport());
        });
    }
 
    void payForPurchase(string orderId)
    {
        PlayFabClientAPI.PayForPurchase(new PayForPurchaseRequest() 
        {
            OrderId = orderId,
            ProviderName = "PayPal",
            Currency = "RM"
        }, result => {
            // Handle success
            Debug.Log("Pay for purchase was successful");
            confirmPurchase(orderId);
        }, error => {
            // Handle error
            Debug.LogError(error.GenerateErrorReport());
        });
    }
 
    void confirmPurchase(string orderId)
    {
        PlayFabClientAPI.ConfirmPurchase(new ConfirmPurchaseRequest() 
        {
            OrderId = orderId
        }, result => {
            //Handle success
            Debug.Log("Comfirm purchase was successful");
 
        }, error => {
            //Handle error
            Debug.LogError(error.GenerateErrorReport());
        });
    }

If anyone has a solution let me know. I feel like the answer is obvious, I'm just missing something here.
