How to send a POST request through Google Apps Script?

Question

Google Apps Script

I want to send a POST request to one senler mailing service with data inside and still need to pass the key I



wrote the following code below. In payload, I pass the necessary data for the service to add a subscriber to the chatbot. In the header I pass the access key.

function senler(){
var data = {
  'vk_group_id': 163864515,
  'v': 2,
  'vk_user_id': 132528477,
  'bot_id': 356810,
};
var options = {
  'method': 'post',
  'contentType': 'application/json',
  'payload': JSON.stringify(data),
  'headers': {'access_token': 'ee95------------------------------------------6'},
};
var response = UrlFetchApp.fetch('https://senler.ru/api/bots/addSubscriber', options);
Logger.log(response.getResponseCode());
}

I execute the code, it seems like 200 comes in response. But in fact nothing changes in the senler service, it turns out that I'm doing something wrong. Moreover, 200 comes even when I send a request without an access key, and this is clearly something wrong.



Tell me, please, what could be wrong and how to fix it? Thanks in advance!

UPD
Replaced the command in logger.log and now it is already clear that there is some kind of error

There was a solution, many thanks to Grigory Boev !
It was necessary to place the key in payload and remove "JSON.stringify"
Working code:

function senler(){
var data = {
  'access_token': 'ee---------------------------------------6',
  'vk_group_id': 1----------5,
  'v': 2,
  'vk_user_id': 1------------7,
//  'subscription_id': 0,
  'bot_id': 356810,
};
var options = {
  'method': 'post',
  'payload': data
};
var response = UrlFetchApp.fetch('https://senler.ru/api/bots/addSubscriber', options);
Logger.log(response.getResponseCode());
}
