    // for sample code showing how to obtain a Wish access token for desktop apps.

    // This example assumes we previously obtained an OAuth2 access token for Wish.

    jsonToken = CkJsonObjectW_Create();
    success = CkJsonObjectW_LoadFile(jsonToken,L"qa_data/tokens/wish.json");

        return;
    }

    // The access token JSON looks something like this:

    // Note: In most OAuth2 implementations, the token endpoint is the same for both the
    // refresh request and the exchange-code-for-token request (which happens when getting
    // the OAuth2 token for the 1st time).   Wish uses a different URL for the refresh:
    CkOAuth2W_putTokenEndpoint(oauth2,L"https://merchant.wish.com/api/v3/oauth/refresh_token");

    // The following uncommon option was added in Chilkat v9.5.0.85
