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

-- Use your actual access token instead of 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:
local sbUrl = chilkat.StringBuilder.new()
sbUrl:append("https://app.watrend.com/api/send.php?")
sbUrl:append(req:get_url_encoded_params())
local responseBodyStr = http:quick_get_str(sbUrl:get_as_string())
-- The responseBodyStr contains the JSON response from the server..

req.http_verb = "POST"
req.content_type = "application/x-www-form-urlencoded"

local resp = chilkat.HttpResponse.new()
local success = http:http_req("https://app.watrend.com/api/send.php", req, resp)
if not success then
    print(http.last_error_text)
    return
end

local sbResponseBody = chilkat.StringBuilder.new()
resp:get_body_sb(sbResponseBody)

local respStatusCode = resp.status_code
print("Response Status Code = " .. respStatusCode)
if respStatusCode >= 400 then
    print("Response Header:")
    print(resp.header)
    print("Failed.")
    return
end

print(resp.body_str)

-- 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"}

local jResp = chilkat.JsonObject.new()
jResp:load_sb(sbResponseBody)

local status = jResp:string_of("status")
