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

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

    let jsonToken = CkoJsonObject()!
    var success: Bool = jsonToken.loadFile("qa_data/tokens/qb-access-token.json")
    if success != true {
        print("Failed to load qb-access-token.json")
        return
    }

    // The access token JSON looks something like this:

    // {
    //   "expires_in": 3600,
    //   "x_refresh_token_expires_in": 8726400,
    //   "refresh_token": "L011546037639r ... 3vR2DrbOmg0Sdagw",
    //   "access_token": "eyJlbmMiOiJBMTI4Q0 ... oETJEMbeggg",
    //   "token_type": "bearer"
    // }

    // This code sends the following request:

    // POST https://developer.api.intuit.com/v2/oauth2/tokens/revoke HTTP/1.1
    // Accept: application/json
    // Authorization: Basic UTM0dVB...wM1d2
    // Content-Type: application/json
    // 
    // {
    //     "token": "{bearerToken or refreshToken}"
    // }

    let http = CkoHttp()!
    http.setRequestHeader("Accept", value: "application/json")
    http.basicAuth = true
    http.login = "QUICKBOOKS-CLIENT-ID"
    http.password = "QUICKBOOKS-CLIENT-SECRET"

    let json = CkoJsonObject()!
    json.update("token", value: jsonToken.string(of: "access_token"))

    var url: String? = "https://developer.api.intuit.com/v2/oauth2/tokens/revoke"
    var resp: CkoHttpResponse? = http.postJson3(url, contentType: "application/json", json: json)
    if http.lastMethodSuccess != true {
        print("\(http.lastErrorText!)")
        return
    }

    print("Response status code = \(resp!.statusCode.intValue)")
