* Demonstrates how to use Basic Authentication in a REST API call for Twilio.
* Sends an SMS text message..

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

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
loRest = CreateObject('Chilkat.Rest')

* Use Basic Authentication.
* Your Twilio Account SID is the username.
* Your Twilio Auth Token is the password.
lnSuccess = loRest.SetAuthBasic("TWILIO_ACCOUNT_SID","TWILIO_AUTH_TOKEN")

* Make the initial connection (without sending a request yet) to Twilio.
lnBTls = 1
lnPort = 443
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("api.twilio.com",lnPort,lnBTls,lnBAutoReconnect)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    CANCEL
ENDIF

* Provide the information for the SMS text message:
lnSuccess = loRest.AddQueryParam("To","+16518675309")
lnSuccess = loRest.AddQueryParam("From","+15005550006")
lnSuccess = loRest.AddQueryParam("Body","Hey Jenny! Good luck on the bar exam!")
lnSuccess = loRest.AddQueryParam("MediaUrl","http://farm2.static.flickr.com/1075/1404618563_3ed9a44a3a.jpg")

* Send the SMS text message.
* Your Twilio Account SID is part of the URI path:
lcResponseJson = loRest.FullRequestFormUrlEncoded("POST","/2010-04-01/Accounts/TWILIO_ACCOUNT_SID/Messages.json")
IF (loRest.LastMethodSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loRest
    CANCEL
ENDIF

* When successful, the response status code will equal 201.
IF (loRest.ResponseStatusCode <> 201) THEN
    * Examine the request/response to see what happened.
    ? "response status code = " + STR(loRest.ResponseStatusCode)
    ? "response status text = " + loRest.ResponseStatusText
    ? "response header: " + loRest.ResponseHeader
    ? "response body (if any): " + lcResponseJson
    ? "---"
    ? "LastRequestStartLine: " + loRest.LastRequestStartLine
    ? "LastRequestHeader: " + loRest.LastRequestHeader
    RELEASE loRest
    CANCEL
ENDIF

* The response is JSON.  We'll show how to get a few bits of information from it.
* A full sample JSON response is shown below..

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.EmitCompact = 0
lnSuccess = loJson.Load(lcResponseJson)

* First show the entire JSON.
? loJson.Emit()

* Now get some individual pieces of information:
? "sid: " + loJson.StringOf("sid")
? "body: " + loJson.StringOf("body")
? "media: " + loJson.StringOf("subresource_uris.media")

? "Success."

* Sample JSON response:
