Syntax

HRESULT XStoreGetUserPurchaseIdAsync(  
         const XStoreContextHandle storeContextHandle,  
         const char* serviceTicket,  
         const char* publisherUserId,  
         XAsyncBlock* async  
)

Parameters

storeContextHandle _In_
Type: XStoreContextHandle

The store context handle for the user returned by XStoreCreateContext.

serviceTicket _In_z_
Type: char*

The service ticket associated with the purchase.

publisherUserId _In_z_
Type: char*

A string containing the publisher user ID.

async _Inout_
Type: XAsyncBlock*

An XAsyncBlock defining the asynchronous work being done. The XAsyncBlock can be used to poll for the call's status and retrieve call results. See XAsyncBlock for more information.

Return value

Type: HRESULT

HRESULT success or error code.

Remarks

To retrieve the customer's purchase ID as well as the execution result of this function call XStoreGetUserPurchaseIdResult after calling this function. To retrieve the size of the customer's purchase ID call XStoreGetUSerPurchaseIdResultSize after calling this function. Knowing the result size will help you read the result more efficiently.

The following code snippet shows an example of retrieving a customer purchase ID.

void CALLBACK GetUserPurchaseIdCallback(XAsyncBlock* asyncBlock)
{
    size_t size;
    HRESULT hr = XStoreGetUserPurchaseIdResultSize(
        asyncBlock,
        &size);

    if (FAILED(hr))
    {
        printf("Failed retrieve the user purchase ID size: 0x%x\r\n", hr);
        return;
    }

    char* result = new char[size];
    hr = XStoreGetUserPurchaseIdResult(
        asyncBlock,
        size,
        result);

    if (FAILED(hr))
    {
        printf("Failed retrieve the user purchase ID result: 0x%x\r\n", hr);
        delete[] result;
        return;
    }

    printf("result: %s\r\n", result);

    delete[] result;
}

void GetUserPurchaseId(XStoreContextHandle storeContextHandle, XTaskQueueHandle taskQueueHandle, const char* serviceTicket, const char* publisherUserId)
{
    auto asyncBlock = std::make_unique<XAsyncBlock>();
    ZeroMemory(asyncBlock.get(), sizeof(*asyncBlock));
    asyncBlock->queue = taskQueueHandle;
    asyncBlock->context = taskQueueHandle;
    asyncBlock->callback = GetUserPurchaseIdCallback;

    HRESULT hr = XStoreGetUserPurchaseIdAsync(
        storeContextHandle,
        serviceTicket,
        publisherUserId,
        asyncBlock.get());

    if (FAILED(hr))
    {
        printf("Failed to get user purchase ID: 0x%x\r\n", hr);
        return;
    }

    // Wait a while for the callbacks to run
    Sleep(5000);
}
