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

// Use the Chilkat Email API to create or load an email.
CkoEmail *email = [[CkoEmail alloc] init];
email.Subject = @"This is a test GMail email created using Chilkat.";
email.Charset = @"utf-8";
[email AddPlainTextAlternativeBody: @"This is a test"];
[email AddHtmlAlternativeBody: @"<html><body><p>This is a <b>test</b></body></html>"];

// We'll need to get the full MIME of the email encoded to a base64url string.
CkoStringBuilder *sbMime = [[CkoStringBuilder alloc] init];
[email GetMimeSb: sbMime];
[sbMime Encode: @"base64url" charset: @"utf-8"];

// The body of the HTTP request will be JSON..
CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json UpdateSb: @"message.raw" sb: sbMime];

// Upload the email to GMail as a draft.
CkoHttp *http = [[CkoHttp alloc] init];
http.AuthToken = @"GMAIL-ACCESS-TOKEN";

NSString *url = @"https://www.googleapis.com/gmail/v1/users/me/drafts";
CkoHttpResponse *resp = [[CkoHttpResponse alloc] init];
success = [http HttpJson: @"POST" url: url json: json contentType: @"application/json" response: resp];
if (success == NO) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

// A status code of 200 indicates success.
NSLog(@"%@%d",@"Response status code: ",[resp.StatusCode intValue]);
NSLog(@"%@",@"Response body:");
NSLog(@"%@",resp.BodyStr);

// The response body contains JSON.
// Use the online tool at Generate JSON Parsing Code
// to generate JSON parsing code.

// A sample successful JSON response:

// {
//  "id": "r-2607584557788895307",
//  "message": {
//   "id": "166f09932c662e93",

//   "labelIds": [
