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

loHttp = CreateObject('Chilkat.Http')

* Use your actual access token instead of 555555555555555555555555555555
loReq = CreateObject('Chilkat.HttpRequest')
loReq.AddParam("number","84933313xxx")

* Note: The WaTrend online documentation indicate a POST should be used.
* However, it seems you might actually need to send a GET request.
* It is unclear.  
* If a GET is neeed, you would just send to the URL w/ query params like this:
loSbUrl = CreateObject('Chilkat.StringBuilder')
loSbUrl.Append("https://app.watrend.com/api/send.php?")
loSbUrl.Append(loReq.GetUrlEncodedParams())
lcResponseBodyStr = loHttp.QuickGetStr(loSbUrl.GetAsString())
* The responseBodyStr contains the JSON response from the server..

loReq.HttpVerb = "POST"
loReq.ContentType = "application/x-www-form-urlencoded"

loResp = CreateObject('Chilkat.HttpResponse')
lnSuccess = loHttp.HttpReq("https://app.watrend.com/api/send.php",loReq,loResp)

    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loReq
    RELEASE loSbUrl
    RELEASE loResp
    CANCEL

loSbResponseBody = CreateObject('Chilkat.StringBuilder')

? "Response Status Code = " + STR(lnRespStatusCode)

    ? loResp.Header
    ? "Failed."
    RELEASE loHttp

    CANCEL

* Both success and failed responses use 200 status code.

* A success response contains this JSON in the response body:
* {"status":"success", ... }

* A failed response will contain something like this:
* {"status":"error","message":"License Invalidated"}
