Example:

Creating a SimpleRestRequest object

/* Create a 'Telegram' request in REST Requests (sys_rest_requests) table
and the 'Send Message' method in REST Request Methods (sys_rest_request_method) table related with 'Telegram' request.
Also create 'chat_id' and 'text' Rest Request Method Param (sys_rest_request_method_param) related with 'Send Message' method
*/

const request = sws.restRequestV1('Telegram', 'Send Message');
request.setStringParameter('chat_id', '123456789');
request.setStringParameter('text', 'telegram');
const response = request.execute();

// OR

const request = sws.restRequestV1();
request.setRequestUrl('https://api.telegram.org/bot1860462740:AAHyP6BMH2Mh-cXezrTVu2sJUoNYvimMRMQ/sendMessage');
request.setQueryParameter('chat_id', '123456789');

const response = request.execute();

addFileContent(content, paramName, fileName)

The method prepares a file in binary format for sending it in a request.
