    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    // See Get Wish OAuth2 Access Token 
    // 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.

    let jsonToken = CkoJsonObject()
    var success: Bool = jsonToken.LoadFile("qa_data/tokens/wish.json")
    if success != true {
        print("Failed to load wish.json")
        return
    }

    // The access token JSON looks something like this:

    // {
    //   "message": "",
    //   "code": 0,
    //   "data": {
    //     "access_token": "15af1c191c1243b029bc1660b5c08ce7",

    // }

    let oauth2 = CkoOAuth2()

    // 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:
    oauth2.TokenEndpoint = "https://merchant.wish.com/api/v3/oauth/refresh_token"

    // The following uncommon option was added in Chilkat v9.5.0.85
    oauth2.UncommonOptions = "EXCHANGE_CODE_FOR_TOKEN_USING_GET"

    // Replace these with actual values.
    oauth2.ClientId = "WISH-CLIENT-ID"
    oauth2.ClientSecret = "WISH-CLIENT-SECRET"

    // Get the "refresh_token"
    oauth2.RefreshToken = jsonToken.StringOf("data.refresh_token")

    // Send the HTTP request to refresh the access token..
    success = oauth2.RefreshAccessToken()
    if success != true {
        print("\(oauth2.LastErrorText)")
        return
    }

    // Save the new JSON access token response to a file.
    // The access + refresh tokens contained in this JSON will be needed for the next refresh.
    let sbJson = CkoStringBuilder()
    sbJson.Append(oauth2.AccessTokenResponse)
    sbJson.WriteFile("qa_data/tokens/wish.json", charset: "utf-8", emitBom: false)

    print("OAuth2 token refreshed!")
    print("New Access Token = \(oauth2.AccessToken)")

}
