// 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.

CkoRest *rest = [[CkoRest alloc] init];

// Use Basic Authentication.
// Your Twilio Account SID is the username.
// Your Twilio Auth Token is the password.
BOOL success = [rest SetAuthBasic: @"TWILIO_ACCOUNT_SID" password: @"TWILIO_AUTH_TOKEN"];

// Make the initial connection (without sending a request yet) to Twilio.
BOOL bTls = YES;

BOOL bAutoReconnect = YES;

    NSLog(@"%@",rest.LastErrorText);
    return;

// Provide the information for the SMS text message:
success = [rest AddQueryParam: @"To" value: @"+16518675309"];
success = [rest AddQueryParam: @"From" value: @"+15005550006"];
success = [rest AddQueryParam: @"Body" value: @"Hey Jenny! Good luck on the bar exam!"];
success = [rest AddQueryParam: @"MediaUrl" value: @"http://farm2.static.flickr.com/1075/1404618563_3ed9a44a3a.jpg"];

// Send the SMS text message.
// Your Twilio Account SID is part of the URI path:
NSString *responseJson = [rest FullRequestFormUrlEncoded: @"POST" uriPath: @"/2010-04-01/Accounts/TWILIO_ACCOUNT_SID/Messages.json"];
if (rest.LastMethodSuccess != YES) {
    NSLog(@"%@",rest.LastErrorText);
    return;

// When successful, the response status code will equal 201.
if ([rest.ResponseStatusCode intValue] != 201) {
    // Examine the request/response to see what happened.
    NSLog(@"%@%d",@"response status code = ",[rest.ResponseStatusCode intValue]);

// 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..

CkoJsonObject *json = [[CkoJsonObject alloc] init];

// First show the entire JSON.

// Now get some individual pieces of information:
