UrlFetchApp Google Scripts VS Node Fetch - node.js

Question

I'm having some problems to do a simple POST request with UrlFetchApp on Google Scripts.
This code works fine on NodeJS with node-fetch lib.
const fetch = require('node-fetch');
const URL = "https://login.XXXXXXXXXXXXX.com.br/api/login"
fetch(URL, {
"body": "{'my_json_data': 'login data'}",
"method": "POST",
}).then(res => res.text())
.then(body => console.log(JSON.parse(body)));
The same request on a Google Scripts project using UrlFetchApp give me a 403 Forbidden HTTP error.
var url = 'https://login.XXXXXXXXX.com.br/api/login';
var data = {
'email':'EMAIL',
'password':'PASS'
}
var options = {
method: 'POST',
payload: JSON.stringify(data)
}
var response = UrlFetchApp.fetch(url, options);
Logger.log(response)
What am I missing here?
Edit: Already tried with payload.

I believe your goal as follows.
You want to convert the following Node.js script to Google Apps Script.
const fetch = require('node-fetch');
const URL = "https://login.XXXXXXXXXXXXX.com.br/api/login"
fetch(URL, {
"body": "{'my_json_data': 'login data'}",
"method": "POST",
}).then(res => res.text())
.then(body => console.log(JSON.parse(body)));
Modification points:
In your Node.js script, the data of "{'my_json_data': 'login data'}" is sent to data as text/plain. So in this case, when UrlFetchApp is used, the content type is required to be set. Because when the content type is not set, the data is sent as form-data.
When above points are reflected to your script, it becomes as follows.
Modified script:
From:
var options = {
method: 'POST',
payload: JSON.stringify(data)
}
To:
var options = {
method: 'POST',
payload: JSON.stringify(data),
contentType: "text/plain"
}
If contentType: "text/plain" occurs an error, please modify it to contentType: "text/plain;charset=UTF-8".
Although I'm not sure about the specification of your API, I thought that contentType: "application/json" might be able to be also used. But this is my guess.
