bool success;

// Use the Chilkat Email API to create or load an email.
Chilkat.Email email = new Chilkat.Email();
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.
Chilkat.StringBuilder sbMime = new Chilkat.StringBuilder();
email.GetMimeSb(sbMime);
sbMime.Encode("base64url","utf-8");

// The body of the HTTP request will be JSON..
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.UpdateSb("message.raw",sbMime);

// Upload the email to GMail as a draft.
Chilkat.Http http = new Chilkat.Http();
http.AuthToken = "GMAIL-ACCESS-TOKEN";

string url = "https://www.googleapis.com/gmail/v1/users/me/drafts";
Chilkat.HttpResponse resp = http.PostJson3(url,"application/json",json);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

// A status code of 200 indicates success.
Debug.WriteLine("Response status code: " + Convert.ToString(resp.StatusCode));
Debug.WriteLine("Response body:");
Debug.WriteLine(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:

// {
