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

Chilkat.Http http = new Chilkat.Http();
bool success;

// Use your actual access token instead of 555555555555555555555555555555
Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.AddParam("number","84933313xxx");
req.AddParam("type","text");
req.AddParam("message","This is a test message");
req.AddParam("instance_id","609ACF283XXXX");
req.AddParam("access_token","555555555555555555555555555555");

// 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:
Chilkat.StringBuilder sbUrl = new Chilkat.StringBuilder();
sbUrl.Append("https://app.watrend.com/api/send.php?");
sbUrl.Append(req.GetUrlEncodedParams());
string responseBodyStr = http.QuickGetStr(sbUrl.GetAsString());
// The responseBodyStr contains the JSON response from the server..

// If a POST is needed, then it is sent like this:
Chilkat.HttpResponse resp = http.PostUrlEncoded("https://app.watrend.com/api/send.php",req);
if (http.LastMethodSuccess == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

Chilkat.StringBuilder sbResponseBody = new Chilkat.StringBuilder();
resp.GetBodySb(sbResponseBody);

int respStatusCode = resp.StatusCode;
Debug.WriteLine("Response Status Code = " + Convert.ToString(respStatusCode));
if (respStatusCode >= 400) {
    Debug.WriteLine("Response Header:");
    Debug.WriteLine(resp.Header);
    Debug.WriteLine("Failed.");

    return;
}

Debug.WriteLine(resp.BodyStr);

// 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"}

Chilkat.JsonObject jResp = new Chilkat.JsonObject();
jResp.LoadSb(sbResponseBody);

string status = jResp.StringOf("status");
Debug.WriteLine("status: " + status);
