How to make a simple POST request from Node?

Question

Node.js

I'm trying to send a regular POST with Node/Express and I'm getting a response:
No 'Access-Control-Allow-Origin' header is present on the requested resource.

const https = require('https');
const options = {
  hostname: 'connect.stripe.com',
  port: 443,
  path: '/oauth/token',
  method: 'POST',
  headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}

const req = https.request(
  options, res => 
    res.on('data', d => 
      process.stdout.write(d))
)
req.write(data) // client_secret=stripe_sk&grant_type=authorization_code...
req.end()

Can any other headers interfere at the Express level?
From Postman, everything exchanges perfectly.

Please tell me where to dig?
