  // 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.
  const email = new 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.
  const sbMime = new StringBuilder();
  email.getMimeSb(sbMime);
  sbMime.encode('base64url', 'utf-8');

  // The body of the HTTP request will be JSON..
  const json = new JsonObject();
  json.updateSb('message.raw', sbMime);

  // Upload the email to GMail as a draft.
  const http = new Http();
  http.authToken = 'GMAIL-ACCESS-TOKEN';

  const url = 'https://www.googleapis.com/gmail/v1/users/me/drafts';
  const resp = new HttpResponse();
  try {
    await http.httpJsonAsync('POST', url, json, 'application/json', resp);
  } catch {
    console.log(http.lastErrorText);
    return;
  }

  // A status code of 200 indicates success.
  console.log(`Response status code: ${resp.statusCode}`);
  console.log('Response body:');
  console.log(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",
  //   "threadId": "166f09932c662e93",
  //   "labelIds": [
  //    "DRAFT"
  //   ]
  //  }
  // }
